地面压裂弱化厚硬顶板防治冲击地压技术研究及应用
Application of ground fracturing weakening thick and hard roof in preventing rock burst
摘要
Abstract
In view of the problem of rock burst induced by high thick roof,it is difficult for conventional pressure relief meth-ods to achieve the goal of regional pressure relief to prevent rock burst.We put forward the method of preventing rock burst by presplitting roof in surface area,analyze the principle of pressure relief and anti-scour of presplitting roof,and design the scheme of surface fracturing and anti-scour in Mengcun coal mine.During the field test,the monitoring systems of ground microseism and underground microseism,geoacoustic and stress are installed,and the joint monitoring system of multi-field and multi-parameter such as"fracture field-vibration field-stress field"is constructed.The test results show that the surface fracturing can effectively promote the release of energy in the high stress concentration area of the fracturing area,and the effect of weakening the target strata is better.关键词
