The invention discloses a roof bed separation water and coal-measure gas collaborative draining method. A coal-rock bed profile structure comprises a vertical well, a horizontal well, a horizontal well horizontal section, a horizontal well vertical section, a horizontal well deflecting section, a sealing device, agoaf, a coal bed, a curving sinking zone, a working face, a hard rock stratum, a softrock stratum, bed separation space and an unmined area. The roof bed separation water and coal-measure gas collaborative draining method comprises the following steps of (1), an individually coal bedgas mining stage, (2), a water-draining and gas-mining synchronized stage, and (3), an individually roof bed separation water draining stage. According to the roof bed separation water and coal-measure gas collaborative draining method, coal-measure gas drainage and mining, coal production and mine well bed separation water hazard prevention and cure are combined, the gas content in the coal bed,the working face, the goaf and a roadway when coal is stoped is reduced,the harm of gas to coal mine safety production is reduced, under the effect of the coal mining, desorption and output of methane are improved, output of coal-measure gas is increased,and the bed separation water in the bed separation space in the roof of a coal mine goafcan be prevented and cured as well; and secondary roof bed separation water hazard accidents are prevented, and the roof bed separation water and coal-measure gas collaborative draining method has great economic and social benefits.
