【摘要】：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。
[Abstract]:In order to reduce the harm of deep well heat damage to downhole workers and orderly production, it is necessary to make clear the influence degree of deep well heat release on deep well heat damage. This paper puts forward the concept of thermal contribution rate of deep well mining, combining with literature investigation and engineering practice data, through seasonal variation of temperature and humidity in air flow, determines the self-compression heat transfer of deep well air caused by different temperature and humidity into air flow. Surrounding rock heat transfer, ore cooling and exothermic, ore oxidation exothermic, filling heat release, mechanical and electrical equipment exothermic, personnel heat source contribution rate change, as well as air wells, alleys. The thermal contribution rate and the thermal contribution density of the section in the working face are changed. The heat source heat release curve, the contribution rate of the heat source, the thermal contribution rate of the section and the heat contribution density of the section in different seasons are obtained to guide the treatment of heat damage.
