摘要:
河东煤田乡宁矿区是山西省主要的炼焦用煤产地之一，王家岭煤矿位于乡宁矿区南部，矿井初期设计生产能力为600万t/a，采用平硐开采，王家岭井田的奥陶系岩溶地下水水位标高在主采煤层2#煤和10#煤以上，属于奥灰水带压。本文通过对煤系地层含水层的补给来源，补给方式以及径流排泄关系分析，确定矿井水文地质特征，为矿井的防治水技术路线和防治水技术措施、防治水方案提供依据。
Xiangning mining area in the Hedong Coalfield is one of the main coking coal production areas in Shanxi. Wangjialing Coal Mine lies in the south part of Xiangning mining area with 6 million tons/year of the initial design production capacity and adit exploration. The water level of the Ordovician karst groundwater, lying in Wangjialing Coal, is above 2# coal an 10# of the main coal seam. Based on the analysis of relations among supply sources, supply ways and runoff discharge, it determines hydrology & geology characteristics of coal mine and provides evidence for technology and measures of water-proofing.
