Abstract

Disclosed are deep coal and terrestrial heat cooperation mining equipment and a method. The equipment comprises a terrestrial heat mining ground system, a terrestrial heat mining underground system, acoal mining system and a filling mining system. The method comprises the steps that a filling coal face is arranged according to a coal seam condition to form a mining system body and a filling system body; a goaf is filled with a heat absorbing, heat storage and normally paste-like filling material, heat mining pipes are laid in the heat absorbing and heat storage filling body, and a heat absorbing belt and a heat insulating belt are formed; and a cold fluid is injected from the ground into the working face for replacing the stored heat in the filling body to form a hot fluid, and the hot fluid is conveyed to the ground for power generation utilization. According to the deep coal and terrestrial heat cooperation mining equipment and the method, cooperation of deep filling and terrestrialheat mining is achieved, the temperature of the working face is decreased, and meanwhile, rationalization development and utilization of resources are enhanced.

Description

technical field [0001] The invention relates to a deep coal and geothermal cooperative mining equipment and method, and belongs to the technical field of deep coal resource filling and mining. Background technique [0002] At present, the mining of deep coal resources has become normalized, especially in the mining conditions of 1000-2000m deep coal resources. Under the mining environment of complex geological conditions, high ground stress, high and low temperature, high karst water pressure, high gas and high-strength disturbance, potential catastrophes The process is concentrated in the increase of rockburst frequency and intensity, strong mine pressure in stope, unpredictable surface subsidence, and strong mining activity disturbance. Deep resource mining and disaster prevention and control are facing severe challenges. [0003] Filling coal mining technology has significant technical advantages in rock movement control and potential disaster prevention and control, soli...
