新田煤矿开采对黔西樱桃坪水库渗漏影响规律分析

以黔西北某拟建中型水利工程与附近煤矿相互关系为背景,在分析、评价拟建水库与煤矿的水文地质结构、岩体特征、相互关系的基础上,采用有限元理论的渗流模型,模拟了煤矿开采对水库渗漏的影响及不同退采距离下的水库渗漏情况,对其渗漏水量进行了模拟计算,分析了水库渗漏的相关影响因素及煤矿开采对水库渗漏影响的规律,为禁采区设置范围及副坝建造位置提供了依据。

Analysis of the Influence of Xintian Coal Mining on the Leakage of the Yingtaoping Reservoir in Qianxi

Based on the relationship between the northwest of Guizhou Province and medium-sized water conservancy pro-ject and a nearby coal mine ,this paper analyzed and evaluated the hydrogeological structure ,reservoir and coal rock mass characteristics ,on the basis of mutual relations ,and a seepage model based on finite element theory was developed to simulate the leakage of reservoir and different retreat mining distance effect on reservoir leakage coal mining ,the water leakage was simulated , and the influencing factors and regularity of coal mining on reservoir leakage were analyzed , which could provide basis for the ban area setting range and side dam construction .
