韩家洼煤业22301综放工作面水灾害防治技术应用研究

Application of water disaster prevention technology in No.22301 Caving Face of Hanjiawa Mine

为进一步提高韩家洼煤业22301综放工作面的回采能力、矿井抗水灾能力,结合矿井生产环节、地面设施等现有条件,充分考虑矿井的管理水平和技术现状,设计制定了一系列防治水灾的安全技术措施。设计该井田主要使用瞬变电磁探测方法进行超前探水,工作面设置一个临时水仓,配备小水泵进行排水,并辅以定期开展观测、收集水文地质数据,绘制积水图等工作,防范水灾。

In order to further improve the recovery capacity and flood resistance in No.22301 Caving Face of Hanjiawa Mine, a series of safety technical measures for flood prevention and control were designed and formulated in combination with the existing conditions such as mine production links and ground facilities, and fully considering the management level and technical status of the mine. The mine field was designed to use transient electromagnetic detection method for advanced water exploration. A temporary water bin was set up in the working face, and small pumps were equipped for drainage. Besides, regular observation, collection of hydrogeological data and drawing of water accumulation map weree supplemented to prevent floods.
