Abstract: The present invention discloses a multi-energy complementary system for a co-associated abandoned mine and a use method. The multi-energy complementary system for a co-associated abandoned mine includes a mining mechanism, a grouting mechanism and an energy mechanism. In the present invention, the mining of coal and uranium resources is realized through the mining mechanism, the subsidence and seepage reduction of the stratum is realized through the grouting mechanism, and the effective utilization of waste resources is realized through the energy mechanism. Finally, with the efficient cooperation of the three mechanisms, safe and efficient development and utilization of co-associated resources in the full life cycle are realized, and the purposes of green and efficient mining of coal and uranium resources and secondary development of a coal seam goaf are achieved, thereby facilitating the realization of dual-carbon goals and the development of low-carbon green energy.

Abstract: A gas-liquid spray dust settlement system for a fully mechanized mining face includes an atomization humidification subsystem, a boundary mist curtain subsystem, and a dust mist recycling subsystem that are all arranged outside the fully mechanized mining face, where the boundary mist curtain subsystem includes high-pressure blade nozzles mounted to hydraulic supports. The atomization humidification subsystem includes a spray dust settler mounted to a rocker arm of a coal cutter and configured to spray water mist completely covering the high-pressure blade nozzle. The dust mist recycling subsystem includes a wind-water linkage dust remover mounted to a semi-encircling support base, arranged under the spray dust settler, and configured to collect the water mist sprayed by the spray dust settler.
