The invention provides a pack roadway or chamber supporting method. The method includes: supporting a drilling chamber by means of sprayed concrete and anchor combined support or bolt-suspended net and sprayed concrete combined support; supporting an extracted ore transverse drift by means of bolt, anchor net and sprayed concrete combined support; using the sprayed concrete, bolt and metal net combined supporting as primary supporting, and supporting an extracted ore access top line by means of a moulded reinforced concrete support when deformation of surrounding rock reaches a certain stability degree. The pack roadway or chamber supporting method is applicable to excavating and supporting of pack or loose, soft and broken media similar to the pack in the roadway or chamber project. The problem that engineered supporting in the pack is quite difficult is solved by the method, a stope is effectively controlled and managed, stability of the pack is guaranteed, supporting efficiency is improved greatly, support cost is lowered, and extraction economic benefit is increased.
