摘要
西南地区煤炭资源丰富,但水文地质条件复杂,岩溶发育,对煤矿开采构成极大威胁。本文选取四川省某煤矿作为研究对象,通过水文地质条件和涌水现状调查,结合地区降雨特点,预算了矿井丰、枯水季节的涌水量,分析矿区岩溶水分布特征和赋存形态,研究了煤矿开采对地区水资源以及对开采煤层上下伏含水层的影响,为煤矿的安全生产提供科学指导依据。
Southwest China is rich in coal resources,but complex hydrogeological conditions and karst development pose a great threat to coal mining.This paper selects a coal mine in Sichuan Province as the research object,through the investigation of hydrogeological conditions and water inflow status,combined with the characteristics of regional rainfall,estimates the water inflow of the mine in wet and dry seasons,analyzes the distribution characteristics and occurrence forms of karst water in the mining area,and studies the impact of coal mining on regional water resources and the upper and lower aquifers of the mining coal seam,so as to provide scientific guidance for the safe production of coal mine.
