摘　　要：为降低工作面水害威胁,实现安全高效回采,以陈四楼煤矿2803工作面底板水害为研究背景,对工作面地质构造、地层空间展布、水源补给等方面综合分析。在工作面与车场施工观测、疏放钻孔,并在区域整体底板改造工程实施疏堵结合方案。结果表明:工作面底板水位整体下降-173 m,疏降效果显著;煤层底板含水层注浆总量6222 t,改造加固效果较理想,工作面回采期间未出现出水现象,实现了安全带压开采,对于改进陈四楼煤矿底板水害防治技术手段具有重要意义。In order to reduce the threat of water damage in the working face and achieve safe and effi-cient mining,taking the floor water damage of 2803 working face in Chensilou Coal Mine as the research background,the geological structure,stratum spatial distribution and water supply of the working face are comprehensively analyzed.In the working face and the yard observation and drainage drilling holes are car-ried out,and the implementation of the combined scheme of dredging and plugging in the overall floor re-construction project in the region are carried out.The results show that the water level of the working face floor decreases by-173 m as a whole,and the effect of dredging is remarkable.The total amount of grout-ing in the aquifer of the coal seam floor is 6222 t.The effect of transformation and reinforcement is ideal.There is no water leakage during the mining period of the working face,and the safe mining with pressure is realized.It is of great significance to improve the technical means of floor water disaster prevention and con-trol in Chensilou Coal Mine.
