摘要
通过对滨湖煤矿16煤层水文地质条件、充水条件的分析,综合考虑开采对底板的破坏,隔水层的阻力及承压水等因素,利用安全隔水层厚度法、突水系数法和底板阻水厚度法,分别对掘进巷道和工作面回采受水威胁程度进行了评价。为以后的矿井防治水工作及确保16煤安全生产提供依据。
Through the analysis of the hydrogeological conditions and the water filling conditions of Binhu coal mine 16 coal, comprehensive consideration of mining floor damage, aquifer and confined water resistance and other factors, the use of safe aquifuge thickness method, water inrush coefficient and water blocking plate thickness method, the degree threatened by water during the mining is evaluated, which provide the basis for the 16 coal production safety.
