摘要
本文在对何家堡煤业矿井地质情况和水文地质情况进行分析的基础上,采用突水系数法、安全水头值法2种方法对各可采煤层回采工作面底板奥灰水带压开采情况进行评价,以进行比较佐证结论,为矿井科学合理地进行生产布局提供了前提基础,从而保证整个矿井的安全高效生产。
Based on the analysis of the geological and hydrogeological conditions of Hejiabao coal mine,this paper adopts two methods of water inrush coefficient method and safe water head value method to evaluate the mining situation of Ordovician limestone water with pressure in the floor of the working face of each minable coal seam,so as to compare and prove the conclusion,which provides a prerequisite for the scientific and reasonable production layout of the mine,so then to ensure the mining safety and efficiency.
