我矿22121炮采工作面生产中出水为9 m3／h,下副巷曾和地方小煤矿打通,小煤矿可能的涌水为110m3／h(整个下副巷地质部门提供的最大涌水量为120m3／h)。 根据生产情况,决定在22121下副巷小煤矿的出水点处安装泵房。由于泵房标高远高于排水管出口的标高,水泵启动后,涌水会在自流状态下流向出水口。 排水参数:最大涌水量Qmax=120 m3／h;排水标高H=7.6m:排水线路全长L=1200m;出水点处泵房标高-168.8m;中部巷道仓凹处标高-258m;22泵房水仓入口标高-281m;高差水头H=116m。
I mine 22121 artillery mining face production effluent 9 m3 / h, the next lane has been opened up and local small coal mines, small coal mines may inflow of 110m3 / h (the entire lower lane geology department to provide the maximum inflow of 120m3 / h). According to the production situation, it was decided to install a pump house at the water exit point of the minor coal mine under 22,121. As the pump room mark is much higher than the height of the outlet of the drain, after the pump is started, the gushing water will flow to the outlet in a gravity flow state. Drainage parameters: Maximum water inflow Qmax = 120 m3 / h; Drainage elevation H = 7.6m: Drainage line length L = 1200m; Pumping point elevation of -168.8m; Water tank entrance elevation -281m; head height difference H = 116m.
