我国冶金矿山矿床类型复杂,矿床开采方法多种多样。因此矿山压力表现形式,造成的危害及与其作斗争的方法也不相同。下面简要介绍一些研究地压的方法和防治措施。一、大面积地压活动及老采空区处理问题不少矿山经长期或大规模开采以后,形成大量的地下采空区未作处理;近年来一些采用留矿法开采急倾斜薄及中厚矿脉的矿山,一般都不留矿房间柱,并部分回收顶底柱。这样就进一步形成了走向长几百米、延
The types of metallurgical mine deposits in our country are complex, and the methods of deposit mining are varied. Therefore, the manifestations of the pressure on the mine, the hazards caused and the methods of fighting it are not the same. Here is a brief introduction to some of the methods of pressure and prevention and control measures. A large area of pressure activities and the old goaf processing problems Many mines after long-term or large-scale mining, the formation of a large number of underground goaf untreated; in recent years some of the use of retention mining method mining sharp and thin Mine veins, generally do not stay in the mining column, and part of the recovery top and bottom pillars. This further formed a few hundred meters in length, extended
