retreat / pillar robbing Explanation: Retreat mining is the removal of pillars in the underground mining technique known as room and pillar mining. - https://en.wikipedia.org/wiki/Retreat_mining -- Retreat mining - A system of robbing pillars in which the robbing line, or line through the faces of the pillars being extracted, retreats from the boundary toward the shaft or mine mouth. - https://www.dep.pa.gov/Business/Land/Mining/BureauofMineSafe... -------------------------------------------------- Note added at 54 mins (2023-04-19 19:42:39 GMT) -------------------------------------------------- This practice is known as “pillar robbing,” though to get away from the negative picture that this raises, it may be called “pulling” or “drawing” the pillars. Essentially the miners will start at the boundary and work back towards the shaft, removing coal from the pillars in a systematic pattern as they go. And if you pull out the supports that hold the roof up, then that roof will collapse into the opening beneath it. - http://theoildrum.com/node/6683 |
