About: coal mine roof fall afrter pillaring


Boy I sure remember those days!
I worked 20 years in the mine can remember roof bolts pinging taking weight then here it comes.
Best part towards the very end.
Why did it rumble for so long was that an earth quake
holy shit were they trapped?!! hey did they fucking get out without being pilled up by gravel?!!
What is the low frequency noise for muchof this? Was it falling in at our locations? Dang sure a dark that words can't describe.
0:04 look in the middle of the pillars. Wtf is that little beed of light???
Marikana Lonmin Mine is experiencing a fatal falls of ground on its shaft. every week Inspectors issues us with section 54's. poor supporting of ground, hurry production for bonus. Guys please jopa kalo standard kalo mine. Lonmin LIFE RULES Number 1 and 2
Red hat, green hat and then straight to pulling pillars at 21 in the 70's. I know the sound and expectations very well. We had a few that refused to drop until we were already all the way back to the belt entry and nothing but air was holding it all up. I'm talking football field lengths that blew doors open all the way to bottom (cage). Thanks for posting.
this is hilarious..  I watched this video and thought man that looks like the black king (mine I worked at a while back)  turns out it was the black king lol  I pulled that block and did not realize it.  That mine has really hard sandstone top,  when pillaring you may not have a good fall for weeks just little ones.. then it all comes in lol
Its been 16 years since I've worked underground and the sound of those timbers taking weight and a roof fall still clears the plaque out of my arteries...lol. Thanks for sharing.
Lmao....that was draw rock not a fall.. and the mine I work at it falls like volkswagons in front of my bolter an we just bolt threw it...
the good old days .bring back pillar extraction timber and we will see the real coal miners not some of the blow hards that work underground today. I love this love the noise the team work and the mateship .finding it in most modern underground mines these days is not going to happen well done boys
I miss things like this
you call that a roof fall! what a joke
That is so scary! I don't know how you guys do this as part of a normal day and keep your cool. Amazing!
