摘要
在中国经济发展的过程中,对开采煤矿所造成的影响也越来越重视,其中采空区水害问题作为在实际生产过程中重点考虑的问题之一。文章以对刘桥一矿为例,圈定采空区,并计算水位回升过程中矿井采空区积水体积以及分析在矿井闭坑后水位回升的时空过程。以此为矿界隔水煤柱的安全性评价提供可靠的依据,实现绿色闭坑以及保证周边矿井的安全生产。
In the process of China’s economic development,more and more attention has been paid to the impact of coal mining.Taking liuqiao no.1 mine as an example,this paper delineates the goaf,calculates the volume of water in the goaf during the rise of water level,and analyzes the temporal and spatial process of the rise of water level after mine closure.This provides a reliable basis for the safety evaluation of coal pillars separating water in the coal mine boundary to realize green pit closure and ensure the safety production of surrounding mines.
