probably one of the better videos explaining the drawbells (funnels) in the block caving

Excellent, instructive video. Thanks! 3 years on, I imagine technology and graphics have evolved. Best I've seen so far, though.

when drilling the lifters (bottom row of holes)are usually drilled out first to prevent the fines ( waste material from drilling) from blocking access to them, they are then fitted with "lifter tubes"so they are still accessible after the fines have piled up at the bottom.

thanks for the video! it was very well described and explained!

Beautiful work guud luck

WOW!! me hubiera gustado que tuviera algún tipo de sonido mientras estaba el video que alguien estuviera comentando.

Me gusta el video Entendí un poco de minería.

excelente, solo falto el audio y una persona expicando

Well done

Talk about double-handling!

is there a survey mining here?

its so giant and so slow process i just wonder why they just not digged fron the top and how it will not colapse after a timeall this mega cave will not last long stable

Split sets are illegal in Canada for use in the back...this must be a depiction of mining in other jurisdictions...where life is cheaper.

This Block Caving looks way too complicated - just cut the roof off the hill & open cast the seams...

10-15 years establishing the infrastructure,then draw the ore body until depleted or subsidence becomes an issue.
