DWX型悬浮式液压支柱一次采全高的应用与实践

Application and Practice of Full-seam Mining with DWX Suspended Hydraulic Prop

总结了刘河煤矿二2煤层采煤工作面一次采全高的经验,介绍了DWX35型悬浮式单体液压支柱的安全性能和技术特点,通过对比,指出了DZ型单体液压支柱的技术缺陷和存在的安全隐患,实现了采煤工作面的安全回采,提高了煤炭资源回收率,取得了明显的经济效益和社会效益。

The experience of full - seam mining of the coal face in No. 22 coal seam of Liuhe Coal Mine issummed up. The safe performance and technical characteristics of DWX35 type suspension single hydraulic prop are introduced. The technical defect and safe problems of DZ type single hydraulic prop are pointed out. The safe mining of coal faces is realized. The recovery rate of coal resource is raised. The obvious economic and social benefits are obtained.
