某铜矿首采区水文地质特征及涌水量预测

Hydrogeological characteristics and water yield prediction of certain first copper mining area

首采区即为某矿山的一期采选工程。本文对某铜矿矿区的地质构造进行了分析,绘制裂隙玫瑰花图,进而更直观地了解矿区裂隙构造发育情况。通过现场详细调查及搜集分析区内及平硐YD1的水文地质、工程地质与静止(混合)水位观测钻孔资料,对首采区的水文地质特征有了明确的认识。依据矿床充水因素,按地下水和大气降水两部分进行涌水量预测,其中地下水部分利用大井法和比拟法预测,最后预测了首采区总涌水量和最大涌水量,可为矿山设计部门制定一系列排水措施提供可靠依据。

The first mining area is the mining engineering phase 1 of certain mine. Through analyzing the mine geological structure and drawing the rose diagram of the fissures,the development of more fracture structures in the mining area are intuitively understand. Based on the details investigation and the collecting and analyzing data of the adit YD1,hydrogeology,engineering geology and static（ mixed） water level observation,the hydrogeological characteristics of the first mining area are clearly understood. The first mining area is divided into the two parts of the groundwater inflow and the precipitation to forecast the water yield based on the factors of the deposit,and the big-well and the hydrgeological analogy methods are used to predict the groundwater. Finally, the total water amount and the maximum discharge are forecasted,which could provide the reliable basis for the mine design department to develop a series of draining measures.
