摘要
通过对某钨矿展开调查,查找矿井主要热源,并分析热害对井下人员、安全生产的危害。结合该矿的热害原因、通风效率及矿山热害防治经验,综合考虑降温成本和实施难度,提出了优化通风系统、提高通风效率、增加作业面进风量的通风降温方案,应用矿井三维通风仿真系统模拟解算,可有效降低作业面温度,控制井下热害。
Through the investigation of a tungsten mine, the main heat source of the mine was found out, and the harm of heat damage to underground personnel and safe production was analyzed. Combined with thermal damage reasons of the mine, ventilation efficiency, and thermal pollution prevention and control experience in mines, considering the cooling cost and implementation difficulty, put forward the optimization of ventilation system, improve the efficienc＇y of ventilation, increase operation into the air ventilation and cooling scheme.Through the simulation and calculation of the 3d mine ventilation simulation system, the temperature of the working face can be effectively reduced and the underground heat damage can be controlled.
