煤矿采准巷道冲击地压机理初探

Preliminary Analysis of Mechanism of Pressure Bump in Developing Workings of CoaJ Mines

冲击地压是一种严重威胁矿井生产的灾害,大部分发生在采准巷道。本文从采煤方法、煤体应力分布,支护强度及采动影响等几方面,对发生机理进行探讨,并提出防治措施。

Pressure bump mostly occurring in developing workings is a hazard posing severe menace to mining operations. An analysis is made of the mechanism of such hazard from various aspects including mining methods, distribution of stress in coal mass, support intensity and mining disturbance . Precaution measures to combat the hazard are proposed .
