The Ordovician limestone aquifer under the steep coal seam mining safety evaluation research on prevention measures of water disaster

针对赵各庄矿井急倾斜煤层开采区域3839工作面发生的涌水情况,对区域涌水量的变化规律进行分析,确定了主要影响因素;对恢复开采的有利条件和不利条件进行了分析对比,提出了安全开采对策和防治水措施。

In view of the gushing water occuring in 3839 working face in Zhaogezhuang Mine steeply inclined coal seam mining area,the change law of regional water inflow is analyzed to determine the main factors. The favorable and unfavorable conditions of the restoration and exploitation are analyzed and compared,and the exploitation countermeasures and measures of water prevention and control are put forward.
