摘要
通过对安家岭一号井综放工作面支架工作阻力、围岩应力、顶煤活动等的实测研究,得出了综放工作面矿压显现规律,为实现浅埋深特厚综放工作面安全高效回采提供了依据。
Underground pressure behavior rules were obtained by observation of working resistance of supports, stress of surrounding rock and movement of top coal in full-mechanized caving mining face in Anjialing 1 st Mine, which provided foundation of safe and high- effect mining for full-mechanized caving mining face in shallow buried and extremely thick coal seam.
