徐庄煤矿是1979年12月建成投产的老矿井,设计生产能力0.9Mt/a,经过技术改造,目前核定生产能力为1.8Mt/a。矿井自投产以来,对生产影响较大的水害为7号煤层顶板砂岩裂隙涌水。2010年全矿井正常涌水量为220m3/h,矿井设计正常排水能力为560m3/h,最大排水能力为1120m3/h。7199工作面位于矿井东九采区深部,开采深度为-582m,工作面储量104万t。工作面开采前,
Xuzhuang Coal Mine is an old mine completed and put into operation in December 1979 with a designed production capacity of 0.9Mt / a. After technological transformation, the current approved production capacity is 1.8Mt / a. Since the mine has been put into operation, the water damage that has a great impact on the production is the fissure water inflow on the top of No.7 coal seam sandstone. In 2010 the normal mine water inflow of 220m3 / h, mine drainage capacity of normal design of 560m3 / h, the maximum drainage capacity of 1120m3 / h. The 7199 face is located in the deep part of the Dongjiatou mining area with a mining depth of -582m and a working face reserve of 1.04 million tons. Face mining before,
