摘要
冲击地压是世界范围内井工煤矿开采遇到的严重动力灾害,对煤矿安全高效开采构成严重威胁,我国是煤矿冲击地压最严重的国家之一,彬长矿区也是冲击地压在内多种灾害叠加区域.经过多年的探索和研究,我国在冲击地压理论及预防技术和装备方面取得了一定的研究成果,冲击地压得到了一定的控制,说明目前的防治措施具有一定有效性.但是,彬长矿区冲击地压事故仍时有发生,没有得到根本遏制.因此,开展煤柱回收工作面防冲技术研究及安全高效回采关键技术研究具有重要的现实意义.通过对下沟煤矿煤柱回收工作面进行简要分析,对防冲的治理工作提出一些看法.
Abstract
Rock burst is a serious dynamic disaster in the world,which threatens the safety and efficiency of coal mining.China is one of the countries with the most serious rock burst in coal mines.Binchang mining area is also a superposition ar-ea of various disasters including rock burst.After years of exploration and related research,some research results have been obtained in the theory of rock burst,prevention technology and equipment,and the disaster of rock burst has been controlled to a certain extent,which shows that the current prevention and control measures have a certain degree of effectiveness,but rock burst accidents still occur in Binchang mining area,and have not been fundamentally contained.Therefore,it is of great practical significance to study the anti-scour technology and the key technology of safe and efficient mining in coal pillar re-covery face.This paper briefly analyzes the coal pillar recovery face in Xiagou coal mine,and puts forward some views on the treatment of anti-scour.
