摘要
近年来,我国冲击地压的研究与防治工作取得了突破性进展,目前已跻于世界先进水平。所取得的成果主要包括:深化煤岩冲击倾向的研究,锤击波速法测量支承压力,掌握地音与微震监测方法,监测系统的技术改造与国产化,研制成功智能便携式矿用地音仪,合理的开采技术措施受到高度重视,试验研究煤层卸载爆破方法,形成综合防治体系并取得了显著的效益。目前的工作与完全控制这一灾害还有相当的距离。今后必须加强防治、预测和机理研究工作。
In the recent years,a breakthrough has been made in research for prevention of rockburst in China,which has made China approach the world most advanced level.The main achievements are made:further investigation of rockburst liability;survey of abutment pressure by hammer wave speed method;master of acoustic emission and microseismic monitoring techniques;modification and domestic fabrication of monitor system.,development of portable intelligent acoustic emission monitor;adoption of rational mining techniques;disstressing of coal seam by blasting method;and establishment of a comprehensive prevention system with remarkable benefit.Currently,there is a long way to go for complete control of rockburst.It is necessary to promote prevention and prediction of rockburst and to pursue study of its mechanism.
