Abstract:In order to speed up the preparation schedule of coal roadway tunneling in Huainan mining area under normal production sequence,the transportation roadway of 1541 (1) working face,a gob side entry driving working face,was taken as the research object.The support design was optimized according to the construction experience,roadway geological conditions and theoretical calculation of bolt mesh (cable) support,increasing the spacing from 0.9m to 1.2m in the roadway roof.Practice showed the roadway satisfied ventilation,material transporting and working face installation of working face during tunneling,achieving favorable effect of cost decreasing and benefit increasing on the premise of safe production.
