【摘要】：据实测,某金属矿井开采深度千米以下的-200m中段的气温高达33.950C,深井高温热害已严重制约了该矿的安全高效开采和深部资源开发。由于该矿所采取的一般通风方法降温效果有限,为改善井下作业环境,必须采取相应的人工制冷降温技术措施。本文分析了该矿井下主要热源及其危害,通过对热源散热量的理论计算,运用矿井空调技术,对以冷水、冰作为冷源的地面集中降温系统分别进行了设计,并对这二种冷媒集中制冷系统进行技术经济分析。以冰作为冷源在深矿井集中降温系统中,其技术经济优势比较明显,也是以后深矿井降温的一个发展方向。
[Abstract]:According to the actual measurement, the temperature in the middle section of -200m is as high as 33.950C in the mining depth of a metal mine. The high temperature thermal damage in deep well has seriously restricted the safe and efficient exploitation and deep resource development of the mine. Because of the limited cooling effect of the general ventilation method adopted in the mine, the underground working environment is improved. It is necessary to take corresponding technical measures of artificial cooling and cooling. This paper analyzes the main heat sources and their harm in the mine. Through the theoretical calculation of the heat dissipation from the heat sources and the use of air conditioning technology in the mine, cold water is applied to the mine. The surface centralized cooling system with ice as a cold source was designed respectively, and the two refrigerant centralized cooling systems were analyzed technologically and economically. Ice was used as the cold source in the deep mine centralized cooling system. Its technical and economic advantages are obvious, but also a development direction of deep mine cooling.
