极厚大矿床深井开采通风降温技术研究

摘要

For the selection of ventilation and cooling scheme in deep well,the surface climate has a decisive role. Based on three-dimensional ventilation simulation software Ventsim,and aimed at the main factors of the air temperature,the cooling wind speed,the artificial cooling capacity and so on,the simulation of ventilation and temperature reduction is carried out for Dataigou Iron Mine. Finally,the optimum scheme of ventilation and cooling in the year is obtained,which provides a scientific basis for the selection of the cooling process and the cooling scheme of mine ventilation. In the process of deep well mining,ar-tificial refrigeration has a pivotal influence on the safety production and economic benefit of the mine.%对于深井开采通风降温方案的选择,地表气候具有决定性的作用。基于三维通风仿真软件Ventsim,针对进风温度、降温风速、人工制冷量等主要因素,对大台沟铁矿深井开采进行了全面的通风降温热模拟,最终获得大台沟铁矿深井开采全年通风降温最优方案,为人工制冷工艺与矿山通风降温方案的选择提供了非常重要的科学依据。在深井开采过程中,人工制冷对矿山的安全生产与经济效益均具有非常重要的影响。
