This is a real issue that causes real damages today, but it’s also an issue that a lot of people put a great deal of thought, effort, and ultimately resources into so that we can strike a balance between protection against damage to property and the environment and obtaining the resources that we all depend on.

Grady have you ever done a detailed video on how some of those VERY LARGE sink holes (the ones that eat houses) are filled in so structures can be rebuilt on the sink hole site??

Wouldn&#39;t a reasonably simple and Not TOOOOOO expensive solution be to fill the mine with random debris, dirt and rubble once you&#39;re done with that section of it?

i wonder if during backfilling room and pillar mines they take out the pillars as they are made of valuable minerals

Don&#39;t expect anyone who votes for reform to be able to think.

I live in Wharton NJ, the roads are still closed. All through my complex, which is less than a quarter mile from the holes, pipes for water and gas are bursting, and there&#39;s cracks in the walls.

Canadian Potash miner here. We still use Room and Pillar mining, but our neighboring and competing mine used Chevron mining. They overmined and caused a 40 year flood that eventually caused the loss of their mine

With as much as it comes up lately, it&#39;s starting to feel like you&#39;ve got a bone to pick with Pittsburgh.

Sadly one important question stays unanswered: Where do we get licensed copies of the HHRMM Software?

<a href="https://www.youtube.com/watch?v=RZg1zOKm5wk&amp;t=880">14:40</a> &quot;and now its a lot better&quot; the city where the mud-wizard clip happened, which was a recording of an anti-mining protest, is now square in the middle of a massive pitmine. For coal.
