| Abstract: | Testing the technology retaining a lane for next sublevel in the conveyor lane of "three soft" coal seam face, it proved in favor of the roof stabilization and retrieving material of next sublevel by adopting the combining supporting technology of bolt with cable, including mesh and beam, and artificial to construct coal wall, with some posts of I-steel and the double rank shoulder canopies towards front. It obtained obvious economic and social benefit. |
