福建邵武煤矿地下水系统分区的分析和研究

THE ANALYSIS AND STUDY OF THE DIVISION OF GROUNDWATER SYSTEM AS AN EXAMPLE OF SHAOWU COAL-MINE IN FUJIAN PROVINCE

位于闽北地区的邵武煤矿地质构造、水文地质条件复杂,因而矿井充水条件较为复杂。本文利用地下水动力系统的观点分析,在矿区已有地质、水文地质资料的基础上,概化了矿井水文地质边界,分析了整个矿区地下水补给、径流和排泄的关系,提出了三种不同的径流模式,并进而进行了矿区的地下水动力分区,将全矿区分为强交替区、中等交替区和迟缓交替区,并根据三个分区的不同径流特征,提出"分而治之"的矿井防治水措施。

Shaowu mining area is in the north of Fujian province. In the mining area, the hydrological geology conditions and the tectonics conditions are complicated, as the result： the mining conditions is complex. On the basis of the general geology of the mining area, this paper analyzes primary aquifers and the supply, runoff, drainage of all the mining area, then fix on the hydrological geology boundary, utilizing the analytic viewpoint of groundwater hydrodynamic system. Three kinds of runoff models are educed by the analysis of runoff conditions of surface water and groundwater. Based on the obtained result, we dividethe mining area into three hydrodynamic zones, such as strong alternation zone, middling alternation zone, tardive alternation zone. At last some prevention and cure measures are given on the basis of the different runoff models.
