基于陇东煤田厚黄土层下千米深井热害环境地质特点,分析了陇东煤田热害受围岩散热、空气自压缩升温、顶板承压裂隙水散热、全煤巷开采生产过程产热的典型特征,创新性地提出了热害防治及资源化利用技术模式:HEMS降温技术模式、瓦斯发电及热电冷联供系统降温模式、地面埋管式井下集中制冷降温模式、矿井人工制冰降温技术模式、蒸发冷却深井降温模式及地层储冷技术。
Based on the geological characteristics of the thermal damage environment in the deep-loess layer of the east Longdong coalfield, the thermal damage of the Longdong coalfield was analyzed by heat dissipation of the surrounding rock, air self-compression, roof fissure fissure water heat dissipation and coal seam mining production process. Typical characteristics, innovatively put forward the technical mode of thermal pollution prevention and control and resource utilization: HEMS cooling technology mode, gas generation and thermoelectric cooling system cooling mode, underground buried pipe cooling centralized cooling mode, mine artificial ice cooling technology Mode, evaporative cooling deep well cooling mode and stratum cooling technology.
