| 摘 要： | 济宁三号煤矿深部开采深度超过600 m时，开始出现了冲击地压事故，并且随着开采深度的持续增加，这种灾害越来越严重，往往导致重大的人员伤亡和财产损失。“煤—围岩”系统构造的复杂性、地质构造的不确定性等因素，使得冲击地压发生机理十分复杂、影响因素颇多。根据该矿的地质条件，系统研究了地质构造诱发冲击地压的机理，分析了“断层蠕动”效应及褶皱受力状态，认为煤层的开采深度对冲击地压的发生起主导影响；同时，也分析了最大主应力及工作面回采时次生应力的变化情况，为冲击地压重点区域的监测提供数据支持。利用微震监测系统与Surfer软件对冲击地压的重点发生区域进行预测，预测结果能清晰地阐述该矿冲击地压的发生规律，为冲击地压灾害的防治提供了依据和理论指导。

| Abstract: | When the deep mining depth of Jining No.3 Coal Mine was exceeded 600 m，rock burst accidents began to occur，and with the continuous increase of mining depth，this kind of disaster became more and more serious，causing heavy casualties and property losses.Due to the complexity of the "coal surrounding rock" system，the uncertainty of geological structure and other factors，the occurrence mechanism of rock burst was very complicated and there were many influencing factors.According to the geological conditions of Jining No.3 Coal Mine，the authors systematically studied the mechanism of geological structure inducing rock burst，
analyzed the "fault creep" effect and the stress state of folds；and it was believed that the mining depth of the coal seam had a dominant influence on the occurrence of rock burst.Meanwhile，the main stress and the change of secondary stress during mining at the working face were also analysed，which can provide data support for monitoring key areas of rock burst monitoring.The microseismic monitoring system and surfer software were used to predict the key areas of rock burst，the prediction results can clearly explain the occurrence law of rock burst in the mine，and provide the basis and theoretical guidance for the prevention and control of rock burst disaster. |
