摘要
为总结我国西部地区保水采煤技术发展现状,基于最新文献分析,全面阐述了保水采煤的概念及其地质分区、采煤技术与工艺和环境效应等方面的进展。保水采煤是趋于研究地下水和生态环境阈限的采煤方法;导水裂隙带发育高度探测方法研究仍在进行,在地震勘探、钻探、模拟等方面均有发展;充填开采在顶、底板保护中应用广泛;尽管矿区地下水位变化剧烈,但区域地质环境尚未发生根本变化。保水采煤研究是我国干旱半干旱矿区煤炭开采与水资源保护的理论基础和依据。
To summarize water-preserved mining status quo in northwest China, on the basis of updated research paper analysis, fully expounded progress on aspects of water-preserved mining concept and its geological partitioning, mining technology, techniques and environmental effect. In water-preserved mining has tendency to study thresholds of groundwater and ecological environment; prospect- ing method for water conducted zone height is still going on; seismic prospecting, drilling and numerical simulation are all developing; stoping-and-filling method is widely applied on roof and floor preservation; although mining area groundwater level has violently var- ied, but fundamental changes of regional geological environment have not yet taken place. The water-preserved coal mining study is theoretical principle and basis for coal mining and water resource protection in the country＇ s arid and semi-arid mining areas.
