“机动采掘系统”是指用于掘进煤层巷道和非长壁煤巷的设备,是美国和澳大利亚采矿工业在连续采煤机和作为主要支护手段用的锚杆机的基础上设计和开发出来的。这种系统由于支护稳定性好,把它作为巷道的主要支护方法,在英国已载入史册,可在英国各种开采深度的地质条件下开拓矩形的煤巷,还可用来掘进后退式工作面的顺槽。据预测,在1993至1994年间,英国煤矿215km的掘进计划中,将有80km巷道全部用锚杆支护,还有56km巷道用锚杆支护配 “Mobile Excavation System” refers to the equipment used to drive coal tunnels and non-longwall coal roadways and is designed and developed by the mining industry in the United States and Australia on the basis of continuous shearers and bolters used as primary support measures of. Because of its good supporting and stability, this system has been used as the main supporting method of roadways and has been put on record in the UK. It can open up rectangular coal roadways under the geological conditions of various mining depths in the United Kingdom and can also be used for driving backward Working surface of the groove. It is predicted that from 1993 to 1994, the British coal mine 215km excavation plan, there will be 80km roadway with bolt support, there are 56km roadway with bolt support
