柳塔煤矿水文地质条件勘查及水害应对

Hydrogeological condition exploration and water disaster response in Liuta Coal Mine

为了解决柳塔煤矿一盘区存在的水文地质问题,需进一步查明该古冲沟松散层的水文地质条件,以及1;号煤层房采采空区积水情况,决定在母花海子古冲沟和1;号煤层房采采空区进行水文地质勘探。选择以钻探为主,辅以工程测量、取芯、抽水试验及水样化验的补勘手段,对柳塔煤矿2;号煤层一盘区进行水文地质勘查,分析了2;号煤层一盘区的水文地质条件、充水因素等,并提出了2;号煤层一盘区防治水方面存在的问题和应对措施。得到的相关勘查结果可以为2;号煤层工作面防治水工作提供技术依据。

In order to solve the hydrogeological problems existing in the first panel area of Liuta Coal Mine, it is necessary to further identify the hydrogeological conditions of the loose layer of the ancient gully, as well as the water accumulation in the room pillar mining goaf of No.1;coal seam, and propose to carry out hydrogeological exploration in the Muhuahaizi ancient gully and the goaf of No.1;coal seam.Based on drilling, supplemented by engineering survey, coring, pumping test and water sample test, the hydrogeological exploration of panel 1 in No.2;coal seam of Liuta Coal Mine is carried out, the hydrogeological conditions and water filling factors of panel 1 in No.2;coal seam are analyzed, and the existing problems and countermeasures of water prevention and control in panel 1 of No.2;coal seam are put forward.The relevant exploration results can provide technical basis for water prevention and control of working face in No.2;coal seam.
