大阳煤矿水文地质条件分析

Analysis on Hydro-geological Condition in Dayang Mine

通过对大阳煤矿及周边水文地质基础资料及井上下水文观测数据的调查分析,结合回采工作面水文资料,系统地分析出矿井的充水因素及水文地质条件。采用大井法预测了采掘活动对含水层的影响,并对奥灰含水层进行了突水危险性评价,为矿井的防治水工作提供了有力保障,确保煤矿的安全生产。

By investigation and analysis of hydro-geological data and shaft up and down around, combining with the working face hydrological data, the systematic analysis of the mine water filling factors and hydrogeological conditions were conducted. Big well method was used to predict the impact of mining activities on the aquifer, and the ordovician limestone water inrush risk was evaluated, which provided the powerful safeguard for mine water prevention and control work, ensured the safety of mine production.
