This invention belongs to the field of underground mining, specifically relating to a method for recovering high-grade residual ore under loose rock cover. The method includes the following steps: S1: Constructing a grouting tunnel in the upper middle section of the residual ore pile at the bottom of the stope, adjacent to the intact ore body of a collapsed stope. This grouting tunnel serves as the construction site for grouting in the collapsed area. This method for recovering high-grade residual ore under loose rock cover effectively addresses the technical problem of ore recovery being impossible due to the collapse of the upper rock mass by constructing a concrete-loose rock mass hybrid structure through grouting. Through theoretical calculations, the strength and thickness of the hybrid structure are ensured to impede rock flow, allowing the ore recovery process to break free from dependence on the stability of the rock mass itself. This enables direct recovery of high-grade ore under loose cover conditions, effectively addressing the recovery limitations faced by traditional methods in severely collapsed stopes.
