| 摘 要： | 煤层底板奥灰水是锦瑞煤业主要水害,为了探讨主采煤层奥灰水带压开采的突水危险性,在分析矿井水文地质条件的基础上,采用突水系数法,从大巷层位布置、工作面长度、底板有效隔水层厚度等几个方面,对矿井主采煤层奥灰水突水危险性进行评价,评价结果可为锦瑞煤业奥灰水带压开采提供技术支撑。

| Abstract: | The Ordovician limestone water in coal seam floor is the main water disaster in Jinrui Coal Industry,in order to discuss the risk of water inrush in the main mining seam under the pressure of Ordovician limestone water,based on the analysis of the hydrogeological conditions of the mine,the method of water inrush coefficient is used to evaluate the risk of water inrush in the main mining seam from the aspects of the arrangement of the main roadway,the length of the working face and the thickness of the effective aquiclude of the floor.The evaluation results can provide technical support for the mining of Ordovician limestone under water pressure in Jinrui Coal Industry. |
