摘　　要：地温场是矿井热环境的主要影响因素。采用热电偶地温监测技术,从垂直和水平两个方向进行地温监测,得到该矿垂直平均地温梯度为2.8℃/100 m,-480 m水平以上地温梯度为0.98℃/100 m,-480 m水平以下,地温梯度为5.08℃/100 m;水平地温梯度由南向北分为3个区域,分别为1.5,0.1和1.8℃/100 m,温度由南向北逐渐增高;调热圈厚度为20 m。利用VENTSIM软件建立了地温分布模型,得出该矿地温分布规律,为通风解算奠定了基础。Geothermal field is the main factors which influences the mine thermal environment. Vertical direction and horizontal direction ground temperature are monitored by the thermocouple tempera-ture monitoring technology,vertical direction geothermal gradient is 2.8 ℃/100 m,geothermal gradient is small above 480 m level,and the geothermal gradient is 0.98 ℃/100 m,while below 480 m level,the geothermal gradient is 5.08 ℃/100 m.The horizontal direction geothermal gradient is divided into three regions from south to north of the mining area,they are 1.5,0.1 and 1.8 ℃/100 m respectively and the temperature increased gradually from the south to the north,the thickness of the adjustable hot laps is 20 m.The ground temperature distribution model is established based on VENTSIMsoftware,so,it can lay the foundation for ventilation calculating.
