摘要
老空水水害事故是煤矿主要水害事故。永煤公司所属部分矿井不同程度受老空水害影响,在严格执行“三专两探一撤”和老空水“四步工作法”等煤矿防治水工作要求基础上,结合矿井实际情况,针对沿空下山掘进巷道,研究应用无煤柱沿空掘巷追排水技术代替传统老空水防治技术,实现了老空水治理本质安全,有效保障了企业老空水害治理“零透水”目标,为类似条件矿井防治水工作提供了参考和借鉴。
The goaf water disaster accident is the main water disaster accident in coal mines,the influence factors of goaf water disaster in Yongcheng Coal Industry Company′s mines are relatively big,on the basis of implementing various laws and regulations,strictly carrying out such measures as"Three special,two exploration,one withdrawal"and"Four-step working method"of goaf water,etc.,at the same time,combined with the actual situation of the mine,in view of the gob-side entry driving down the mountain,the technology of water chasing and drainage along the gob without coal pillar is actively applied instead of the traditional technology of water prevention and control in gob-side entry driving,thus realizing the essential safety of water treatment in gob-side entry,the goal of"Zero Water Inrush"is effectively guaranteed.
