山西省阳坡泉煤矿水文地质特征及水压带开采技术研究

阳坡泉煤矿位于鄂尔多斯聚煤盆地东缘的河东煤田中段东边缘。通过对矿区钻井、测井资料、含水岩性组合及出露特征分析，主要含水层为奥陶系石灰岩岩溶裂隙含水层、碎屑岩裂隙含水层、松散岩类孔隙含水层。大气降水、地表水、含水层水、奥灰水是煤田的主要充水来源。根据突水系数法对矿井西翼盘区各主采煤层进行了带压开采安全性评价，10、11、13号煤层最大突水系数值分别为0014、0015、0027 MPa/m，在构造破坏地段工作面回采有可能发生突水。依据该矿井奥灰突水带压评价，提出了该矿井带压开采的路线和安全保障措施，加强导水构造和底板薄弱带的探查与治理，以保障矿井安全开采，同时希望能够为广大同行提供一定的借鉴。

Study on hydrogeological characteristics and mining technology of water pressure zone in Yangpoquan Coal Mine,Shanxi Province

Yangpoquan Coal Mine is located in the eastern margin of Hedong coalfield in the eastern margin of Ordos coal accumulation basin.Based on the analysis of drilling and logging data，water-bearing lithologic assemblage and outcropping characteristics in the mining area，the main aquifers are ordovician limestone karstic fractured aquifer，clastic fractured aquifer and loose rock pore aquifer.Atmospheric precipitation，surface water，aquifer water and Ordovician limestone water are the main sources of water filling in coal fields.According to the water inrush coefficient method，the safety evaluation of each main coal seam in the west wing of the mine was carried out.The maximum water inrush coefficient values of No.10，11 and 13 coal seams are respectively 0014，0015，0027 MPa/m.Water inrush is likely to occur in the mining face at the tectonic damage section.According to the pressure evaluation of ordovician limestone water inrush in the mine，the mining route and safety guarantee measures were put forward，and the exploration and treatment of water conducting structure and weak zone of floor plate were strengthened to guarantee the mine safety mining，at the same time，the author hope to provide a certain reference for the majority of peers.
