利用天然环境同位素示踪法分析华丰煤矿四煤顶板出水水源

Applying the natural isotopic tracer to analyse the water source from the 4th coal roof of Huafeng Coal Mine

通过对华丰煤矿各含水层水样以及四煤顶板出水样的18O、D、3 H同位素值分析 ,指出该矿三采区上下部砾岩含水层连通性差 ,分别由不同水源补给 ;井下四煤顶板出水仍为砂岩水 ,并非注浆水下漏所致。

In this article,through the analysing information of δ 18 O?δD? 3H from the different aquifers and seepage water from coal roof in Huafeng Coal Mine ,the conclusion can be drawn: up and lower sections of conglomerate aquifer of the Tertiary system are not hydaulic connection, they have different origins ,the seepage water from the 4th coal roof is not the injecttion water but sandstone water.
