深埋侏罗系煤层顶板水探放技术实践——以呼吉尔特矿区葫芦素矿井为例

呼吉尔特矿区深埋侏罗系煤层顶板含水层主要为河流相沉积。虽然构造比较简单，主要充水含水层与上覆白垩系及松散沙层间水力联系较弱，但是含、隔水层空间组合及结构较为复杂，富水性极不均一。针对上述特点，采用沉积地质学的研究方法对典型矿井含水层空间展布规律开展了研究，对矿井主要充水的直罗组含水层进行了识别、定位与精细划分，圈定了河流沉积砂体富水条带，并通过井下探放水实践得以验证。 

Practice of exploration and discharge technology of roof water in deep Jurassic coal seam: with Hu Lusu coal mine in Hujiert mine area as example

The sedimentary type of roof aquifer of the deep Jurassic coal seam is mainly fluvial deposition in Hujiert mine area.Although the tectonic conditions are relatively simpleand the hydraulic connection betweenthe main water-bearing stratumwith the Cretaceous and unconsolidated layersaquifers is weak. Butthe space combination relations and structures of the aquifers and aquifugesarevery complex and the water yield propertyis very inhomogeneous. According to the above characteristics, Studied the spatial distribution of typical mineaquifer by the method of sedimentary geology. Identified, located and delimited the Zhiluo aquiferwhich is mainly filled with water in the mine, and delineated the water-rich zone of the sedimentary sand body and it was verified by the practice of underground exploration and drainage water.
