傍河型矿床水文地质特征及矿井水资源化可行性分析——以鹤岗煤田峻德、兴安两矿为例

Analyses of hydrogeological characteristics of a mine along a river and feasibility of utilization of pit water resources——Exemplified by the mines Junde and Xing'an in the Hegang coalfield

本文以鹤岗煤田峻德、兴安两矿为例,作为典型的傍河型孔隙、裂隙充水矿床,对其矿床充水条件和充水来源组成进行了分析,确定鹤立河水侧向补给是矿井涌水的主要来源;通过多年矿井涌水量、补给组成及保障分析,得到其矿井涌水具备充足的补给来源、矿井水资源化具有较大可行性的结论,为此类矿床的研究提供了借鉴和参考。

This paper took the mine s Junde and Xing＇ an in the Hegang coalfield as a typical groundwater-filling mine along a river, and analyzed the groundwater filling conditions and the compositions of pit water sources in the two mines. The results indicate that the lateral recharge of the Heli River is the primary recharge source of pit water. By analyzing the indraft of pit water, compositions and guarantee of recharge, the paper comes to the conclusion that there are abundant recharge sources for pit water, and the utilization of mine water resources is of considerable feasibility. The results are used as the references for the feasibility analysis of utilization of pit water resources in similar mines.
