摘　　要：根据三河尖煤矿水文地质及张庄断层的实际揭露情况,采用分析计算法分别对张庄断层的上下盘防隔水煤柱进行了计算,上盘煤柱按50 m留设,下盘按43. 8～75. 7 m留设,共计解放煤炭资源量96. 6万t,稳定了矿井生产接续,对类似条件的矿井具有一定的借鉴意义。Based on the hydrogeology of Sanhejian Coal Mine and the actual exposure of Zhangzhuang Fault, this paper calculated the water-proof coal pillars on the upper and lower walls of Zhangzhuang Fault by analytical calculation method. The coal pillars on the upper wall are set at 50 m and the coal pillars on the lower wall are set at 43. 8 ~ 75. 7 m. The total amount of liberated coal resources is 966,000 tons, which ensures the production connection of the mine. It has a certain reference significance for similar mines.
