A method for slope geological disaster treatment and mineral resource recovery includes the following steps: S: dividing a mountain top into a plurality of treatment sections and treatment segments; S, selecting an easy-to-slide area at the upper portion of a first treatment segment and blasting an easy-to-slide body to make the easy-to-slide body roll down to a bottom of the slope; S, forming a regular initial slope bench; S, mining coal at the coal seam in a grouped mining adit manner, and laying grouting pipelines in the primary mining adits; S, forming closed mining adits; S, excavating secondary mining adits at intervals of the primary mining adits in sequence; S, continuing mining in an adjacent second treatment segment in the same manner; and S, continuing mining the first treatment segment of the second treatment section in the same manner.

An underground mining method for unexploited coal in a boundary open-pit mine is provided. A shaft construction platform is arranged at one rock step to two rock steps above a coal seam. Intermediate bridges are built starting from a pit bottom. Mining area clay is laid on a working slope where no intermediate bridge is built and on a side slope with an outcrop of the coal seam as a sealing layer to seal the slopes. Auxiliary vertical shafts and main inclined shafts are dug. The pit bottom is dug downward to form a digging space on a side close to the working slope between two adjacent ones of the intermediate bridges, and clay is filled into the digging space to form an artificial water barrier layer. A roadway communicating the main inclined shafts and the auxiliary vertical shafts is constructed, and a coal seam stope face is arranged.
