Control of heat hazards in deep tunnels is vital to underground safety production. Taking a 1010-m-deep coal mine as an example, this paper revealed the variation characteristics of geo-temperature along the depth direction in plain area and the variation characteristics of country rock temperature along the horizontal direction in deep tunnels and the thermodynamic characteristics of the deep space. Using theoretical analysis, numerical simulations, field tests, etc., a new method for calculating cooling loads of deep tunnels and working faces was studied, and heat release law and calculation method of hot water flowing in open canal were discussed. Based on local resource and meteorological conditions and the condition of limited water inflow, the authors designed and implemented the phase-Ⅰ project and phase-Ⅱ project of hazard control system in the 1010-m-deep tunnels. The results showed that the environmental control temperature dropped to 26 ∼ 29 °C, and the average relative humidity was reduced by 5%–15%, which met the comfort standards of underground workers. The failure rate of underground equipment was reduced by half, the investment and operation cost of the heat hazard control system were small, and good environmental and economic and social benefits were achieved.

控制深部隧道热危害对井下安全生产至关重要。以某1010米深煤矿为例，揭示了平原地区地温沿深度方向的变化特征、深部隧道围岩温度沿水平方向的变化特征以及地温热力学特征。深空。采用理论分析、数值模拟、现场试验等方法，研究了深部隧道和工作面冷负荷计算的新方法，探讨了明渠热水的放热规律和计算方法。根据当地资源和气象条件以及来水有限的情况，作者设计并实施了1010米深隧道危险源控制系统一期工程和二期工程。结果表明，环控温度降至26～29℃，平均相对湿度降低5%～15%，满足井下工作人员舒适度标准。井下设备故障率降低一半，热危害控制系统投资和运行费用小，取得了良好的环境和经济社会效益。
