摘要
根据兴隆庄煤矿地质采矿条件,结合松散含水层赋存特征,分析了四采区4303综放工作面第四系松散含水层出水的原因,探讨了防治三含水的技术途径和留设防砂煤柱的合理尺寸。
Based on the geological and mining conditions and occurrence characteristics of loose aquifer of Xinglongzhuang Colliery, water bursting cause of 4303 full-mechanized caving mining face under loose aquifer was analyzed, the prevention measures of the 3rd aquifer and reasonable dimension of coal pillar for sand proof were discussed in this paper.
