【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。更多还原

【Abstract】 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.更多还原
