摘要
根据大同煤田采空区积水的特点,分析以往地质资料,综合物探技术应用,施工地面、井下探放水孔排放积水等手段,采用立体综合方法对大同煤田防治水技术进行研究,有效地排放了采空区积水,保证了煤矿的安全生产。
Based on the goal water features in Datong coal field, the study analyzes in detail past geological data, application of integrated geophysical prospecting technique, and gas drainage on the surface and underground of construction site. A three-dimensional integrated approach is adopted to study the water control technology in Dataong coal field which could drain the goal water and guarantee the safety production in mines.
