为了减小深井热害对井下工作人员及有序生产的危害，需要明确深井各热源放热量对深井的热害影响程度。借鉴经济学理论，提出深井采矿的热贡献率概念。结合文献调查与工程实践数据，通过入风流温湿度的季节性变化，确定不同温湿度入风流所引起深井空气自压缩传热、围岩传热、矿石冷却放热、矿石氧化放热、充填体放热、机电设备放热、人员放热热源贡献率的变化，以及入风井、平巷、工作面中的区段热贡献率及区段热贡献密度的变化。得出了不同季节的热源放热曲线以及热源贡献率、区段热贡献率、区段热贡献密度排序以指导热害治理。

In order to reduce the harm of heat damage to staff in deep mines and to keep the ordered production, it is necessary to determine the influence of different heat sources to heat damage in deep mine. By referencing from economic theory, the concept of thermal contribution rate in deep mine was proposed. Combining with the litera-tures investigation and engineering practical data, by means of the seasonal change in temperature and humidity of the initial airflow, the corresponding changes of thermal contribution rates from different heat sources, such as heat transfer of self-compression air, heat transfer of surrounding rock, heat release of ore cooling, heat release of ore oxidation, heat release of backfill, heat release of electrical and mechanical equipments, heat release of human body etc. , were calculated. The thermal contribution rate and contribution density of intake shaft, drift, working face in various sections of the mine were also achieved. The heat release curves of heat sources in different seasons and the sorting of thermal contribution rate, section thermal contribution rate and section contribution density were obtained, which can be used to guide the thermal damage control.
