开采引起的层间滑动与黄淮地区煤矿井筒破裂关系研究
ON THE RELATION BETWEEN INTERLAYER GLIDE CAUSED BY COAL EXTRACTION AND THE SHAFT RUPTURE OCCURRING IN COAL MINES IN HUANGHUAI AREA
【摘要】 在黄淮地区大量井筒调查资料的基础上,对该地区井筒破裂特征和井筒破裂机理存在的几种不同观点作了述评,研究了开采引起的层间滑动与井筒破裂的关系,提出了井筒破裂可行的治理方法和预防措施。
【Abstract】 Based on the investigation of a large number of coal mine shafts in Huanghuai areai a comprehensive analysis is made on the characteristics of those ruptured shafts in this area. A review is presented on several different opinions about the mechanism of shaft rupture. The relation between interlayer glide caused by coal extraction and the shaft rupture is studied. The method for reinforcement of ruptured shafts is put forward and some measures to prevent rupture of the shaft wall are proposed.
