Abstract: According to the characteristics of deep coal seam occurrence and large mining thickness in Jinshan coal mine,in order to ensure efficient production of coal mine safety,the permanent support of the mining roadway is mainly composed of bolt + anchor cable + mesh,the temporary support uses the ZLJ20 airborne temporary support.Thread steel resin bolts are used as support materials of the top and side roadways.17.8 mm×6 000 mm steel strand is selected for archer cable.4 mm diameter mesh reinforcement is selected for the top neting.The No.8 iron wire metal mesh is selected for the side netting.Based on the above support design,the design and installation technology of bolt,anchor cable and support net are studied and analyzed,which are of certain reference significance to ensure the safety and high efficiency of production.

Key words: Thick coal seam,Mining roadway,Support parameters,Support technology
