适应晋煤集团的 6.2 m 大采高液压支架开发

摘要

晋煤集团3#煤层厚度6m左右 ,赋存稳定 ,有利于大采高工作面布置.结合现有的大采高支架存在的问题和本地煤矿的实际情况 ,开发了6.2m大采高液压支架 ,提高了晋煤集团的煤机设计和制造水平.%The coal seam thickness of 3# coal mine of Jincheng Anthracite Mining Group has been found about 6 m ,conducive to the coalface layout .Combining with the actual situation of the existing large mining height supports and the local coal mine conditions , we research and develop 6 .2 m large mining height hydraulic support ,to improve the design and manufacturing level of coal machine of Jincheng Anthracite Mining Group .
