华北煤田突水潜在区域煤层开采综合防治水技术研究

Study on comprehensive water control technology of coal seam mining in potential areas of water inrush in North China Coalfield

华北煤田构造复杂,煤层底板破碎不完整,部分煤层奥灰突水系数均超过了0.06MPa/m,属于突水潜在区域,这部分煤层能否安全开采直接影响着矿井的生产衔接及未来矿井的发展。针对这些问题,提出了一套井上、下相结合的空间、立体综合防治水技术,并在峰峰矿区部分矿井成功应用,对于类似开采条件煤层的开采具有重要的参考价值和指导意义。

Geological structure in North China Coalfield is complex, with incomplete coal floor. Portions of coal seam water inrush coefficient over 0.06 MPa/m, it belongs to potential water hazard areas, this part of the coal seam can directly affects the safe mining of the mine production links and future development of the mine. So a set of three-dimensional integrated water control technology was put forward, this technology was suceessfuliy applied in FengFeng Mine, with important reference value and guiding significance for mines under similar condition.
