通过对淮北双龙矿业集团公司水文地质特征以及历年突水水源、突水规律的分析和研究,结合设计工作面具体地质特征,提出在向斜轴部开采煤层时,采用双机联运防治煤层顶板砂岩裂隙水,详细介绍了向斜轴部双机联运的采掘工艺,该方法在实践中能有效消除回采过程中的顶板水害,保障矿井安全生产。
Based on the hydrogeological characteristics of Huaibei Ssangyong Mining Company and the analysis and research of the water inrush and water inrush history over the years, combined with the specific geological characteristics of the designed working face, it is proposed that the double-unit operation should be adopted to prevent and control the coal seam roof sandstone Fissure water, and introduces the mining technology of twin-shaft interoperation of the inclined axis section in detail. This method can effectively eliminate the roof water damage during the recovery process and ensure the mine safety production.
