煤矿排水对地面沉降的影响分析

Analysis of Mine Drainage on the Land Subsidence Impact

在煤矿开采引发的地面沉降的众多因素中,地下水的抽排通常是重要的因素之一。本文以贵州松河井田为例,在考虑抽排水的因素影响下通过数学模型预测沉降量,从而完善沉降预测结果。

Ground water pumping is one of the important factors to cause land subsidence by coal mining. Taking the Songhe mining area as an example, this paper improves the subsidence predictions in the circumstances of con- sidering drainage pumping and applying a mathematical model analysis.
