摘要
通过研究采区的开采深度、煤层顶板性质、煤岩冲击倾向性、地质构造和煤层厚度变化等冲击地压影响因素,应用综合指数法预测冲击地压危险性,进一步分析了在采动影响下的冲击危险性,并划分了5个冲击危险性较大的区域。根据应力在线监测和微震系统的实时监测和分析,预测结果比较符合现场实际。
With the study on mining depth,roof and floor strata properties of the seam, the coal and rock burst tendency,geological structure,thickness of coal seamand other rock burst influence factors of the mining block,the comprehensive index method was applied to predict the danger of rock burst.Further analysis of the risk under the influence of mining impacts, impact more dangerous,mark five impact high risk areas. Compare with stress on-line monitoring and real time monitoring of microseismic systems,the prediction results are consistent with the catual.
