240805面是四采区8煤首采工作面,由于该采区8煤层顶板砂岩局部富水性相对较强,8煤顶板砂岩水将威胁该面的安全回采。通过对240805面地质、水文地质条件进行分析,提出工作面回采的水害防治措施。
240805 working face is the first face of the 8th coal seam of the fourth mine area, because the top sand rock of the 8th coal seams is rich of groundwater in some section, the sand rock water of the 8th coal seam will threat the face safe mining. By analyzing the hydrogeologic and geological conditions of 240805 face provides some preventive measures.
