摘要
用地质动力区划方法查明大兴矿井田各级活动断裂,结合应用井下采场地应力测试数据,通过岩体应力计算,对大兴矿井田进行构造应力区划分,查明大兴矿北部采区位于构造高应力区域内,这一区域为煤与瓦斯突出最危险区域。
The geo-dynamic division method is used to identify active faults at various levels in the Daxing mine field. Divides tectonic stress zone of the Daxing mine field using geo-dynamic division method combined with the application of underground mining site stress measurement data, and the rock mass stress calculation. The north mine field of Daxing mine is identified as high structural stress area and the most dangerous area for coal and gas outburst.
