肥城煤田影响矿井突水的地质构造分析与预测

Analysis of Geology Tectonic Influencing Water Bursting and Prediction in Feicheng Coalfield

肥城矿区自1965年开采下组煤以来,曾先后发生过150余次出水。这些出水几乎全与地质构造有关。总结分析了影响矿井出水的地质构造特征、出水机理以及发育规律。对利用突水构造发育规律、含水层错动对接关系等宏观现象和构造面力学性质等微观现象预测预报矿井水害,提出了见解。

150 times of water bursting had happened since the lower coal seam was mined in 1965. They were all related to geology tectonic. The geology tectonic characteristics, water bursting mechanism and growth rule influencing water bursting were analyzed and summarized in this paper. It was put forward that applying macroscopic phenomena such as bursting tectonic and growth rule, aquifer faulting and connecting relationship and microscopic phenomenon such as mechanic property of tectonic level to forecasting mine flood.
