Characteristics Of Geothermal Field Of Deep Mine And Its Heat Damage Control In China

According to the geological tectonic conditions of Zhangshuanglou Coal Mine, The temperature field development law of heat damage is studied, the geothermal anomaly is analyzed and the microclimate characteristics of deep mine heat damage(DMHD) is summarized in the Mine, all of which based on the knowledge of Engineering Geology, Ventilation Security, Engineering Thermodynamics, Coal Mining. At the same time, the deep mine heat damage microclimate enthalpy humidity chart(i-d chart) and wet density map (d-ρ map) in summer days are depicted. The control strategy of microclimate characteristics of DMHD, which is the control system of DMHD, is proposed on the basis of the microclimate characteristics of DMHD and the hydrogeological conditions in Zhangshuanglou Coal Mine. The cold sources of DMHD control system are classified on the ground of the amount of mine swallet. Moreover, the control system is debugged, the operational data is analyzed, the running balance parameters are calculated and the control effect of working face and tunneling face are analysed. In sum, HEMS control system of DMHD obtained a significant effect in Zhangshuanglou Coal Mine.
