为确工作面回采安全，采用综合物探、钻探方式对顶板裂隙水以及 2# 煤层采空区积水情况进行探测、疏排；通过本煤层瓦斯抽采钻孔对煤体内积水以及潜在的隐伏地质构造积水进行疏排；通过封堵地面导水裂隙封堵从而避免地面水渗入到井下回采空间。现场应用后，采面回采期间涌水量控制在 3.6m3/h 以内，涌出量较小，不会给煤炭正常回采带来不利影响。“,”in order to ensure the mining safety of the working face, the comprehensive geophysical exploration and drilling methods are used to detect and drain the roof fissure water and the accumulated water in the gob of 2# coal seam；Through the gas drainage borehole in this coal seam, the accumulated water in the coal body and the potential hidden geological structure is drained；By plugging the surface water flowing fissures, the surface water can be prevented from seeping into the underground mining space. After the field application, the water inflow is controlled within 3.6m3/h during the mining period, and the emission is small, which will not bring adverse effects to the normal coal mining.
