摘　　要：为了全面掌握目前我国冲击地压的发生情况和防治现状,统计分析了近年来我国冲击地压发生的区域、条件、特点以及防治手段和效果。分析结果表明:随着我国煤矿采深的日益加大,冲击地压灾害将越来越严重;坚硬厚层顶板条件和断层、褶曲等构造是冲击地压发生的主要地质因素;开采形成的煤柱应力集中和动载是冲击地压发生的主要开采技术因素。针对目前研究中存在的问题,建议采用物探方法量化地质构造因素的影响并考虑深部条件下瓦斯对冲击地压的影响;研究对冲击地压监测多源数据的综合处理方法;重视对防冲开采设计方法和巷道防冲能力的研究。In order to analyze the occurred situations and the prevention and control status of the mine strata pressure bumping in China,the paper had the statistics on the occurred areas,conditions,features of the mine strata pressure bumping in China as well as the prevention and control means and effect.The paper held that with the mining depth is getting deep and deep in China,the mine pressure bumping disaster would be more and more serious.The hard thick roof condition,the fault and fold and other structures would be the main geological factors to the mine pressure bumping occurred.The coal pillar stress concentrated and dynamic load caused by the coal mining operation would be the main mining technical factors to the mine pressure bumping occurred.The paper proposed that the physical exploration method could be applied to quantify the influences of the geological structure factors.In consideration of the mine gas affected to the mine strata pressure bumping under the deep mine condition,the paper had a study on the comprehensive processing method of the multi source data for the monitoring and measuring of the mine strata pressure bumping and a study on the mine pressure bumping prevention and mining design method and the mine roadway pressure bumping capacity.
