Something happened at a trucking company that was trying to transport my tractor. The kid loaded on a backhoe loader forwards under the trailer because he was on a time crunch. because of this, while he was unloading it, it went sideways off the trailer because it had no weight on the front tires. He also loaded and unloaded it... Always safety first, and let the customer do the loading. Not worth dying for 20 minutes of time savings.

These companies don’t care about people. $$$$$$ is all that matters

any thing you can imagine, some company already has a patent on it and is operating it right now, my dad worked in all types of industry and I've seen some crazy machinery, that you would never think could actually work, men have imagined and built alot of incredible machines.

Long wall mining has been around since the 70’s. I actually design these long wall shearers. Been doing it for almost 12 years now. This animation is an oversimplification. I’ve been underground in a long wall mine. It’s quite the experience. It’s impressive what these machines can do. In fact we have some in China that cut almost 30ft high coal seams. (8m)

@@stevevb988 animation does not show how the material is extracted. Please explain.

@@joeskis Mining Engineering student here. Coal broken up by the shearer falls down and out onto a moving chain (the bending black lines in the animation). The chain drags it out to a feeder, which channels the coal onto a conveyor belt that carries it out of the mine for processing.

@@stevevb988 I work in a steel forge making these bars for the conveyors and the teethed sections that the cutters sit on. JOY Mining if you`ve heard of them.

This should be in Minecraft, it’s faster than a diamond pick.

Right? We're in the dark zone.

Glad you are out of the Big Machine. Everyone deserves to have their life preserved by the company they keep afloat. It should be common sense to protect the people that support your operations.

I worked at the Marfork plant , Massey had labor standards of 1910 , I was glad to leave there

you would think that after so many mining accidents throughout history that these companies would take it more seriously.

@@pleep1887 You are forgetting the almighty dollar my friend. In a board and pillar mine here in Australia our manager, a Scottish fellow, wanted a Deputy to "rob" stook "X" in an extraction panel. In an extraction panel all the big blocks (pillars) get trimmed down from 45m x 45m down to about 12m x 12m from memory as the mining process retreats back out of the panel, leaving the roof to fall in at a sort of controlled rate, hopefully not over running the mobile roof supports and crew. All this gets done to an extraction plan, formulated with the geology and stresses involved to prevent this happening. Which pillars you cut, from what direction, angle etc Stook X is an end pillar critical to that plan and the manager wanted the crew to trim or rob it of supporting coal, all for the sake of production quotas and his job or bonus probably. Risking the crews lives, the bastard!

I worked in both UK and Australian coal mines, in NSW Australia, the Caol Mines Regulation Act required an automatic methane detector on the last roof support on the return air side of the face, WHICH, when it detects Methane in the general body of the air, when that level of methane reaches one and one quarter percent to trip power off the face to all electrical equipment. As the face electrician, I used to "bend the rules" occasionally, BUT if the detector failed to work, that was it I'd shut off power, now way would we cut coal without the detector working, just not worth the risk.

I dont even know why I'm here.

Why would a supervisor have to tell you how to take a dump?

@@actsismmljcorrectlyobeyed6190 Taking a dump won't kill you. None functioning safety equipment will kill you. Is that hard for you to understand?

@@Thomas-cu5hp Its way over your head. You don't get it.

Yup...I wrote up lots of safety deficiencies...nothing ever got fixed because it was too expensive or the crushing plant would need to be shut down to correct it. Couldn't even get enough maintenance men because half the county is on meth, pills, or dope.

The old way, you just push all your downtime to the start or the end of shift and call it "scheduled maintence". Luckily in my time mining there has been a strong shift away from this kind of reporting.

Frank Galvin Thought it was for want of a nail

The water sprayers may have extinguished the ignition source, however the methane explosion is what liberated the coal dust, not the cutting head. Otherwise, the explosion would have only traveled down the return air as this is where coal dust from the face travels.

Float dust. Float dust is released every time a Shield moves, and methane is mixed into it as they're mining. Power plants pulverize coal into dust to burn it..the Shield also pulverize coal and drop it onto the Longwall walkway.

The sprays on the machine are designed to keep the dust down yes, BUT, they won't stop a dust ignition/propagation, thats the job of the stone dust, (rock dust) barriers in the two gate roads, sometimes water barriers, the force of a methane ignition will knock the barriers down or rupture the water barriers which then kill the explosion at that point, preventing the dust explosion fron propagating throught the mines workings, they won't save those men inbye of the barriers though.

There are bachelor's, master's, and Ph.D programs in Occupational Safety and Health, toxicology, industrial hygiene, and safety engineering. You should explore these. There are people who specialize in accident investigation to determine root causes - and, hopefully, prevent their recurrence.

Depends on the accident investigation. Junior guys who tend to be scapegoats when the real guilt lies higher should probably always plead the Fifth unless they have a competent lawyer representing them who recommends otherwise.

@@kirstinmorrell No competent lawyer would ever recommend their client do anything but plead the fifth.

Unless the company was violating mine safety laws. When that happens mine owners go to jail.

well they were and none went to jail

I think the mine owners and the senior folks responsible for ensuring the place is safe and in working condition ought to be at risk of being held to account. These guys treat workers like chattel - as long as they coal keeps coming out of the ground, they can sit in their plush, if tacky, offices a hundred miles away and count their money, safety issues and working conditions be damned. That mentality usually ends up being the actual cause, anyway. Super convenient to just stop at the engineering analysis and say "oh! everyone... make sure you're keeping the sprayers working to keep things cool," without ever stopping to ask why non-functional sprayers were ever considered acceptable by leadership to begin with.

​@Eugene B Lol, best reply I've read for a while!

Per Wikipedia: The Upper Big Branch Mine disaster occurred on April 5, 2010 roughly 1,000 feet underground in Raleigh County, West Virginia at Massey Energy's Upper Big Branch coal mine located in Montcoal. Twenty-nine out of thirty-one miners at the site were killed. The coal dust explosion occurred at 3:27 pm.

@@damnits2200 There were a few other things that happened that year too. I was going through the deep dark parts of youtube, and there were more disasters in 2010 as well.

tungsten..didn't you see the death toll?

Too much force and impractical since it must be ventilated.

Not sure if you watched the video but the methane explosion happened due to dry conditions at the face and after the initial methane explosion it was coal dust blowing up.

@@Mic_Glowalso, a lack of rock dust!

@@scarface9617 yes lack of rock dust is a very good point that with sprays not working and poor ventiltion spells disaster

@@navyseal7036 yessir! I always did put my dust on a lil'thick! I can understand the sprayers (tips) getting clogged up here and there.. but there is just no excuse for the ventilation being bad. But.. it's to late.. once something like this happens buddy!(🤝)

Pure management fault. Shortcuts were ordered to make money. Managers should have gone to prison for life.

I'm an underground coal miner. It's rough work. But it's a lot like being in the army. The men you work with become your brothers. You love them. they are your family. We protect one another and when something like this happens We all die together. It's a bit more comforting.

Can't get it to wet, you will be in a foot of mud working all day!

It would be hard to use the 5th, mines run on paperwork, ie as an electrician, I had to perform Planned Maintenance, , that was daily inspections of electrical equipment in my panel, weekly examinations, Monthly, three monthly and annual. Each had it's limitations, daily was visual inspections all the way up to Annual, which meant a full external and internal inspection of my equipment, then dated and signed to be filed away. Each shift, my daily end of shift reports had to be initialed by my engineer, Under Manager and Manager, so any defects noted by everyone who needed to know and filed away.

@@yauwohn If you really ever worked underground you know better!

Each mine operator has to submit a ventilation plan to MSHA before they can produce coal at the mine. Throughout the life of the mine, changes must be made to that plan as the mine develops. A short time before this explosion, the operator had submitted changes to the ventilation plan that would have addressed the problem of the methane seeping out from behind the shields. MSHA rejected this plan thinking that they knew better. There are some folks at MSHA who are also liable for these miner’s death. You’ll never hear about that.

Don't you guys have a union, I'm an electrician, before I got in the union, my bosses made us work on stuff hot all the time, getting shocked was a weekly event, sometimes many times a day, I'm lucky I lived through the first 15 years of being an electrician, then I got in the union, and never had to work on anything hot again, the owners never asked us to work hot because they knew it was wrong, and the union would come after them if they tried, I would think if you see unsafe working conditions, your union would back you up for reporting them?

Only at certain percentages of methane, 5-15%. Most countries require power be removed at 1 1/4 percent, and all men withdrawn to safety at around 2% methane.

Yup, from pickaxes to machines. Job pays well too, but it is risky business.

26 miners died. A tad short of 299.

You need to get your facts straight. All of what your saying is not true

@@JasonTate86 ...Sorry mate,but you are also wrong,or,you haven't explained how Bord and Pillar,[ or Room and pillar..same thing!],extract all the coal!! ..the purpose of Bord and Pillar is exactly as it says!...you take out the roadways and Intersections..["Stentons" here in Northumberland UK],and you LEAVE in the Pillars!...this is called "Partial Extraction"..as opposed to Longwall mining which is "Total Extraction"..and the pillars which are left in,support the strata and Property or land on the surface. We were mining Bord and Pillar by hand,in the UK,long before your Country was even inhabited by the Goldrush generation! I know nothing of what happened in Utah,but Subsidence is Subsidence all the world over,and although Rules and Regulations were introduced by the British Government in 1947,and 1954,in the Coalmining Industry,Officials underground still gave the miners orders to mine past Boundaries set by the Mine Surveyors...and actually mined under property...a lot of which was never recorded..I know personally,because I had to follow orders,as did all the other Miners at the pit where I worked....or I should have said... ONE of the pits where I worked![over a period of thirty years,from 1959 - on!... with 7 years as a Mine Deputy/Overman].. The only way you could turn Partial extraction [Bord and Pillar] into TOTAL extraction,would be to set up small Retreater faces,usually 60 yards in length.Our Pillars were 60 yards by 60 yards square..as depicted in this Animation. The only thing that puzzles me here is the plan is ALL Bord and Pillar...and I am wondering where the Longwall Face is among all this!! methinks somebody cocked up somewhere!

Actually, Don Blankenship ran for the Senate and lost. His history demonstrates his appropriateness as a staunch Trumpist - a complete disregard for workers in exchange for maximizing profits. As a soulless crook who actually once said conserving gasoline in the 70's was tantamount to the introduction of "communism", he would have made a perfect addition to the current administration. I'm actually surprised he hasn't been nominated for something.

whiteknightcat You are correct, not sure how I messed that up. I had to suffer through all his SENATE mailing and commercials.

10 miles is too close, that's fucking freaky.

It's geology it's high quality anthracite and cokeing coal in deep mines prone to firedamp methane etc, it was needed in the steel industry along with the ore and copious supplies of water all found in the area .

Peg James,I don't know how old you are,but great of you to highlight how much suffering there was in the Mining Industry,just to make Coal-owners Richer and Fatter.I watched the BBC News coverage, on old Black and White Television,in 1966,the day that the Aberfan disaster had happened,after my just finishing a hard shift down a wet,rough,dangerous hell-hole,Called Choppington B Pit..[the "High Pit"],I was 22 years old,and coal cutting and hand-filling on a coalface where the roof used to lower with extreme pressure,as every minute passed..roof falls were frequent..men killed and injured frequently,yet even in the 1960's, the National Coal Board took no action to prevent these dangers to the workforce....it was sometimes difficult to even claim any compensation..to my mind ,any loss of life is a disaster,even one person,...but the NCB,in it's wisdom,defined a Disaster,as the loss of "FIVE OR MORE LIVES"...and I say..try telling ONE Widow and her Children,that their loved one isn't coming home from the pit,but it isn't a Disaster.......

@@highpitwilma what got me was the NCB refusing to accept full responsibility financially, and 150,000 pounds was used from the disaster fund to remove what remained of the spoil heap,and it was not until the 1990s did the high court rule it be repaid By the way I remember dependant on what day it was meant the ebbw was black from the collery , red from the steel works or a brown sludge colour,and every spare bit of ground had a waste tip on it but lots of places for us 10 year olds to have a big adventure playground. I was 10 when aberfan occured.

I have the same question.

I'd bet money it was so they could get the last bit out. And I'd bet they were hitting a lot of rock so there wasn't any coal left after the pass. Everything about their operation says fast, no downtime, no coal left behind.

@@EightiesTV I'd say the bits scraping.. the rock.. is where the spark come from!

No. This was always a long wall mine

No it was a longwall mine but but due to your 40 foot cuts in the conventional cm process you cut crosscuts shorter to have more places to move si you can keep moving without stopping.

Because at the time nothing like this had ever happened. If it's not ESSENTIAL then we keep working. At the time this was a Massey Mine. They take their time fixing things and when the miner is down they lose MILLIONS of dollars. So they kept running it, the Methane built up behind the miner and then the mine exploded and the belt line caught fire, then it collapsed.

Don the Con saved a penny at the risk of miner's lives,I believe the lack of wanting to use the correct amount of rock dust properly required ,safety rules that were hard to follow as I believe the Con required hourly production reports & down time making the miners feel in a state of constant rushing/hurrying for fear of their jobs & everyone knows the least productive can & will be laid off/fired for no reason & I'm pretty sure this was non-union,so to answer your question I would say out of Don the Con Blankenshit's greed a lack of rockdust cost 29 lives & families lives to be ruined & changed forever due to no fault of the miners! Con more than likely fought the families as much as possible to keep from paying them benefits for their loss of a loved 1 & to make it worse fought it in court to blame it on a "coal miner's negligence" which is not true because the 1st thing they think of when riding the belt/car down that deep dark hole is putting in their shift to provide for their family & than return home safely to that home & family waiting for him/her!

@@kaymadden9669 So this is the famous Blankenshit's Disaster. Didn't know, they seem to try to keep his name out of it in the report and didn't even mention any fatalities. I'm sure he's a powerful asshole in the area and has to be protected ya know. So sad that they put production over lives, but that is what they call MBO. Management By Objective, is a corporate management tool. It was used by McNamara in Vietnam. In that version it was body count. Here it was production by tons per day or per shift no doubt. MBO creates a focus on production without looking at the big picture and can be the road to hell imho.
