摘要
通过对刀柱复采工作面地表地形、地物,在回采过程中的移动、变形、塌陷的实测,分析总结了刀柱复采工作面地表地形地物在不同跨煤柱地质条件下的移动、变形、塌陷规律,以便工作面开采时留设合理的保安煤柱,促进工作面的安全高效生产。
The paper analyzed and concluded surface movement,deformation and subsidence rule under different pillar conditions by the observation of surface movement,deformation and subsidence of wedge-pillar secondary mining face.Results might provide reference for rational coal-pillar designing and mining with safety and high efficiency.
