摘要
Abstract
Goaf roadway drivage mining, surrounding rock broken, so need to take the former steel in tunneling working face, and then to charge and blasting work, after conifrmed safe, laid landing net, will use hydraulic prop with long wood top jacking, and then move the ground beam before, put a tent to beam, the coal (bottles) and then planted tent leg, as a roadway drivage cycle.At the same time, developed a goaf mining are broken surrounding rock tunneling advance supporting device, ensure the integrity of the main roof during the blasting excavation tunneling faces, shortens the time of mining roadway drivage of mined-out area.关键词
