中文摘要：

随着开采深度的增加,新城金矿已经进入深部开采阶段,逐步面临高温热害问题。鉴于此,开展地下深部热环境分析,分析矿区主要热源及其形成机理,应用工程热力学手段量测不同开采深度下巷道风流温度、湿度以及风速等环境因素。采用深孔测量法测定不同深度的围岩温度,研究地温梯度变化规律。测试结果表明,巷道风温、水温均随着开采深度的增加而增大,主要生产中段相对湿度在80%RH以上,矿区恒温带温度为23℃,正常地温梯度为0.018℃/m,调热圈半径为17～18 m。该结果为有效控制井下作业场所的热环境状况以及热害防治研究提供了基础数据。

英文摘要：

With the increase of mining depth,Xincheng Gold Mine has entered the stage of deep mining,and is gradually facing with the problem of high temperature stress. In this regard,an analysis of deep underground thermal environment was conducted,the main heat sources and the formation mechanism in the mining area were analyzed,environmental factors such as air temperature,humidity and wind speed of different mining depths of roadways were measured by means of Engineering Thermodynamics. The temperature of surrounding rock in different depths was determined by Deep Hole Measurement Method and the variation regularity of geothermal gradient was studied. Test results show that the air temperature and water temperature of the roadways increase with the increasing of mining depth,the relative humidity of main mining levels are above 80% RH,the temperature of underground constant temperature zone in the mine area is 23 ℃,the normal geothermal gradient is0. 018 ℃ / m,and the radius of heat adjustment circle is 17 ～ 18 m,all these will provide basic data for the effective control of thermal environment conditions in underground workplaces and the prevention and treatment of thermal hazard.
