Research on Heat Disaster Control for Deep Shaft in a Certain Metal Mine

以国内某铜矿深部矿井热害防治为研究实例,阐述了金属矿山高温矿井热源调查的主要内容,通过对矿井内高温环境主要参数的测定与分析,掌握矿井内存在高温现象的主要原因。根据对矿井通风系统调查的实际情况,采用Ventsim软件建立矿井通风系统三维仿真模型,对矿井通风系统进行风流模拟和热模拟,真实地反映井下通风和高温环境的现状。在此基础上,拟定了该矿山深井热害的治理方案,然后进一步使用Ventsim软件反复模拟与优化,确定最佳的实施方案。

Taking the research on heat disaster control for deep shaft in a certain metal mine as an example, the paper describes the main contents of heat source investigation of high temperature shaft of a metal mine, and the main causes of high temperature Phenomenon existed in shaft can be understood by measuring and analyzing the main parameters of high temperature environment in the shaft. According to the .actual situation of investigation of ventilation System, Ventsim software is used to establish the 3D simulation model for ventilation system, by which air flow simulation and thermal＇ simulation can be carried out for ventilat!on system, so as to truly reflect the present situation of the underground ventilation and high temperature environment. On the basis of which, the scheme of the mine heat disaster control can be proposed, and then Ventsim software can be used for repeated simulation and optimization, and finally the optimum implementation scheme will be finalized.
