俄霍布拉克井田水文地质条件复杂。流经井田的水源为北部天山雪溶水及大气降水,第四系是主要的含水层,但导水通道及其补给和排泄条件不清;由于井田的地形复杂,井田内有多条古冲沟。虽然通过物探方法基本查清第四系强含水层的分布情况,但具体导水通道位置不清。矿井东翼最上部第一个综采面1106面推进到Ⅳ-Ⅴ勘探线之间时,发生突水事故。经过分析决定井上、下分别实施防治水方案,通过地面进行电法勘探探查含水层,井下采用电法勘探查明含水层区域,拟在上游采用疏水截流的方法(施工放水巷)。经过在放水巷中对第四系进行打钻放水,1106工作面总涌水量减小到180 m3/h,基本对矿井东翼第四系径流水起到疏水截流的效果,保障了矿井的安全生产。
Russia Hobhula wellfield hydrogeological conditions are complex. The water flowing through the mine field is snow-melting water and atmospheric precipitation in the northern Tianshan Mountains. The Quaternary is the main aquifer, but the water-conducting channels and their supply and discharge conditions are unclear. Due to the complicated topography of the minefield, ditch. Although the distribution of Quaternary aquifer is basically ascertained through geophysical methods, the location of specific aqueduct is unclear. The water inrush occurred when the 1106 face of the first fully mechanized mining face in the uppermost part of the east wing of the mine progressed to the IV-V exploration line. After analysis, it is decided that the water prevention and control scheme should be implemented in the well and the ground respectively. The aquifer should be probed by electrical prospecting through the ground and the aquifer area should be identified by electrical prospecting in the well. The method of water diversion and closure should be adopted in the upstream. After quarrying and draining the quaternary system in the drainage lane, the total water inflow in 1106 face is reduced to 180 m3 / h, which basically plays the role of drainage and closure to the Quaternary runoff in the eastern wing of the mine, thus ensuring the safety of the mine produce.
