摘要: 煤层底板突水是一种复杂的地质及采动影响现象,是煤层下覆承压水冲破底板隔水层的阻隔,以突发、缓发或滞发的形式进入采空区或工作面,造成矿井涌水量增加甚至淹没矿井的自然灾害,因此研究底板突水的预测方法与防治措施十分必要。根据淮北矿业集团公司朱庄煤矿六煤层的埋藏特征,通过大量的现场实测和理论分析,提出了承压水体上开采底板突水的预测方法和防治措施,确定了朱庄煤矿防治水方案,保证了六煤层承压水体上安全开采。

Abstract: Water in-rush of coal floor is a complex geological and mining-affected phenomenon,which refers to the natural disaster that the confined water under the coal seam breaks through the blockage of the floor isolation and comes into the mined-out area of working face in a rush,relax or delayed manner,leading to the increase of water inflow or even submerge the mine.Therefore,it is very necessary to study the forecast method of floor water in-rush and its prevention and control measures.In light of the occurrence characteristics of No.6 coal seam in Zhuzhuang Coal Mine of Huaibei Mining Group,and based on large amount of site measurement and theoretical analysis,the forecast method of water in-rush of floor in mining over confined water body and its prevention and control measures were proposed,and the water prevention and control plan was determined,ensuring the safe mining of No.6 coal seam over confined water body.
