摘　　要：榆神府矿区是我国煤炭资源主要产区之一,为了实现该区煤炭资源绿色化开采,保护当地生态环境,要求必须采取保水采煤技术。查阅了近年来公开发表的关于保水采煤技术的文献资料,归纳总结了保水采煤技术理论发展现状和工程实践现状,并据此指出了该领域的发展趋势。研究结果表明,实现保水采煤核心是要准确预测导水断裂带的发育高度;根据主采煤层覆岩水文地质条件和岩层物理力学性质,确定煤层、主关键层与含水层三者之间的空间位置关系,精确预测导水断裂带高度和研究地下水转移储存条件,是保水采煤的发展趋势。To realize the green mining of Yushenfu Mining Area, one of the major coal resources in China, and protect the local ecological environment, it is required to adopt the technology of water-retaining and mining. Based on the overviews of the recent achievement and the latest development of coal mining under water-preserving, we sum up the theoretical development of water-preserved mining technology and the current situation of engineering practice. In addition, the development trend in this field is pointed out. The results show that the core of water preserved mining is to accurately predict the development height of water flowing fractured zone. According to the hydro-geological conditions and the physical and mechanical properties of the strata in the main coal seam, the spatial relationship between the coal seam, the primary key layer and the aquifer is determined. It is the development trend of water preserved mining to accurately predict the height of water flowing fractured zone and to study the storage condition of groundwater transfer.
