Abstract:
This paper described the characteristics of environmental geology in Longdong 1 000 m deep mine under the thick loess layer and analyzed the thermal damage characteristics by surrounding rock, heat production from the compressed air, the roof pressure fissure water cooling, heat production in full coal roadway mining, proposed the innovation technology of thermal damage control and resource utilization:the HEMS cooling technology model, gas power generation and CCHP system cooling model, underground centralized cooling model by ground buried pipe type, the artificial ice cooling technology model in mine, evaporative cooling and storage technology model.
