%X The bolting support principle is introduced to support roadways in extremely soft seam of coal mine with complex roof. The maintenance of surround rocks is controlled by reinforcing complex roof and two side walls. With an engineering example, a new kind of successful supporting technology is introduced. The roof is reinforced using full column resin bonded high strength bolts and pre stressed anchor ware, and two side walls are strengthened using high water coagulative material grouting.
