摘要
鉴于鑫源煤矿的冲击地压威胁,需要在严格落实各项冲击地压防治措施及各项管理规定的基础上,进行工作面回采作业活动。本文采用综合指数法对冲击危险性进行评价,首先对地质因素影响下的冲击危险性进行分析预测,再对开采因素影响下的冲击危险性进行分析预测,综合考虑两种因素影响下的危险性可以得到,当前采掘范围内整体为无冲击危险。并且,对于应力异常、孤岛工作面等特殊区域,必须进行冲击地压的监测,并根据监测结果及现场情况采取积极主动的卸压措施。
Based on the threat of rock burst in Xinyuan Mine,it is necessary to strictly implement the prevention and control measures of rock burst and various management regulations,and then the mining operation can be carried out.In this paper,the comprehensive index method was used to evaluate the impact risk.Firstly,the impact risk under the influence of geological factors was analyzed and predicted,and then the impact risk under the influence of mining factors was analyzed and predicted.Comprehensively considering the risk under the influence of two factors,there was no impact risk in the current mining scope.In addition,for the special areas such as abnormal stress and isolated island working face,it was necessary to monitor the rock burst,and take active measures to relieve the pressure according to the monitoring results and site conditions.
