保水采煤技术的现状

The current situation of coal mining with water protection technology

叙述了保水采煤技术的意义,分析了浅埋煤层开采岩层控制理论,根据工作面实际情况,分别对矸石充填法、膏体充填法、高水及超高水充填法进行了研究,目前保水采煤的理论与技术得到了较好的发展和应用。

The significance of coal mining with water protection technology is described,and the control theory of shallow buried coal seam mining strata is analyzed.Based upon the actual situation of working faces,the gangue filling method,paste filling method,high water and ultra-high water filling method are separately studied,thereby the currently theory and technology of coal mining with water protection have been well developed and applied.
