摘要
分析了南定地热田中温度在水平和垂直方向上的变化规律 ,探讨了温度场与构造和地下水的关系 ;利用数值法模拟了当煤矿降压排水为 1 5 4 0 0 m3 / d时地下水流场和地热田温度场的变化 .结果表明 ,南定地热田的形成与构造和地下水流场密切相关 ,地热能的传导方式以地下水对流为主 ,热传导为辅 ;地热田与南定煤矿位于同一水文地质单元 。
Temperature variation of Nanding geothermal field in both horizontal and vertical directions was analyzed. The relationship of temperature field as well as geological structure with ground water was discussed. The ground water flow net and temperature field under the condition of drainage being 15 400m 3/d were simulated using digital method. The result shows that the formation of Nanding geothermal field is closely related to geological structure and ground water flow net; The conduction way of geothermal energy is firstly the ground water convection, and then the thermal conduction. The geothermal field and Nanding coal field belong to the same hydrogeological unit.
