Coal and symbiotic sandstone type uranium mine coordinated mining method based on key layer protection

The invention discloses a coal and symbiotic sandstone type uranium mine coordinated mining method based on key layer protection. The method comprises the following steps of drilling from the ground to a coal occurrence stratum in a coal-uranium symbiotic area to obtain geological information; determining a structural key layer and a water-resisting layer in a rock stratum structure according to the geological information; arranging a plurality of short-wall coal mining working faces in a coal mining area at intervals, wherein the plurality of short-wall coal mining working faces advance simultaneously to form a plurality of working face interval strips for coordinated mining; cutting off a roof at the rears and two sides of the short-wall coal mining working faces; drilling holes in a portion, above a goaf filling body, of a roof rock stratum from the working faces and a reserved roadway, and respectively grouting and filling fracture groups which are in communication with each other and roof separation frac
