摘要
岱河煤矿是衰老矿井,由于受采场限制,常常出现没有时间装面的情况。为此,采取掘进装面一次成巷技术,不仅缓解了采掘接替,还大大降低了因装面出现的冒顶事故,避免了回收工字钢等工序,减少了因装面、运工字钢等出现的工伤事故。取得了显著经济效益,可加以推广。
As Daihe Coal Mine stope and often face a lack of time for the equipment. To this end, take a roadway surface excavation equipment, not only ease the mining succeed, but also greatly reduced as a result of a cave equipped with surface to avoid the I - recovery processes to reduce surface as a result of equipment, such as the I - beam transport accidents. Achieved remarkable economic results can be replicated. Key words a roadway surface coal mine drilling equipment.
