摘要
针对煤矿开采导致矿区水资源破坏的严重问题,开采深度逐渐增大,其底板灰岩承压水一直是困扰煤矿安全生产的一个重大隐患.基于承压矿井地形地貌、水系统环境、地质结构类型、覆岩层结构组成及煤层赋存条件.以"三等效"保水开采理论,化矿井水害防治为矿井保水开采为切入点,将矿井浅表水、顶板水及底板水进行整体统筹考虑,紧紧围绕"浅表水保质保量、顶板水资源化利用、底板水原位保护"这条主线.形成可复制可推广的承压矿井保水开采模式系统,形成一套适合类似矿井的"安全、高效、经济、与生态环境相协调"的保水开采技术体系,实现矿井安全开采和保水开采双重目标,打造承压灰岩水矿井绿色开采(保水开采)工程示范基地,为我国矿井保水开采提供可行性指导.
Abstract
In view of the serious problem of water resources destruction caused by coal mining,the mining depth increases gradually,the floor limestone confined water has been a major hidden danger to the safety of coal mining.Based on the topography and geomorphology of confined mine,water system environment,geological structure type,overlying strata structure composition and coal seam occurrence conditions,"three equivalent"water-retaining mining,water disaster prevention and control was taken as the cut-in point of water-retaining mining,the shallow surface water,roof water and floor water were considered as a whole,tightly around the"shallow water quality and quantity,roof water resources utilization,floor water in situ protection"this main line.To form a water-conserving mining model system that can be replicated and popularized,and to form a set of water-conserving mining technology system suitable for similar mines,which is"safe,efficient,economical and in harmony with the ecological environment",to realize the double goals of safe mining and water-preserved mining,to build the green mining(water-preserved mining)project demonstration base of confined limestone water mine,and to provide feasible guidance for water-preserved mining in China.
