矿山井筒涌水量分段预计初探

Segment Is Expected To Mine Shaft Water Inflow Of

目前水文地质试验很难做到分层分段抽水,较多的是将含水层划分为若干含水层组进行混合抽水试验,并计算水文地质参数。因此,应用解析法计算井筒穿越各段涌水量存在一些困难。宁夏煤炭勘察工程公司在银星二号煤矿主斜井、副斜井及回风斜井井筒涌水量计算过程中,试探性地采用考虑含水层岩性粒级、含水层厚度及有效水头高度3个因素的加权平均法,计算得到了银星二号煤矿主斜井、副斜井及回风斜井分段涌水量预计值。

The layered hydrogeologieal test is very difficult to sub-pumping, the aquifer is more divided into groups of mixed aquifer pumping test, and calculate the hydro-geological parameters, therefore, application of analytical method to calculate cross sections of the wetlbore discharge, there are some ditlqculties. Ningxia coal exploration and engineering companies in the Silver Star II mine main shaft, Vice Inchned Shaft Shaft and return air discharge calculation process, the tentative use of grain size into account aquifer lithology, aquifer thickness and effective head height of three factor of the weighted average, calculated the Silver Star II mine main shaft, and the return air shaft, vice inclined discharge section predicted.
