摘　　要：为探索深井矿山巷道围岩调热圈半径测定最优方法,确定试验区巷道围岩调热圈参数大小,以铜坑矿锌多金属矿体所在区域为研究背景,采用数值模拟法、公式法及现场实测法等3种方法分别开展深井矿山巷道围岩调热圈半径变化规律分析研究,研究结果表明:巷道围岩调热圈半径-温度变化规律为一阶指数函数模型;获取了各自条件下研究区域围岩调热圈半径、温度值,但公式法缺陷不能计算调热圈温度;综合对比分析各方法优缺点及结果,最终确定现场实测法最优,其次是数值模拟法,公式法最差,但其可以作为其它研究方法的参考,保证其它研究方法的正确实施。In order to explore the optimal determination meth- od for radius and parameters of heat-adjusting zone in sur- rounding rock at deep roadway, the zinc polymetallic ore ar- ea in Tongkeng mine was taken as the background. Then, the radius variation of heat-adjusting zone was analyzed by numerical simulation method, formula method and field measurement method. The conclusions were obtained as fol- lows. Firstly, the change rule between radius and tempera- tures conformed to the first-order index function model. Sec- ondly, the radius and temperatures of heat-adjusting zone in research area were obtained by each method, but the tern-perature can＇t be calculated due to limitation on formula method. Thirdly, through comprehensive comparison of three methods, the results showed that field measurement was the best, followed by numerical simulation method, and formula method was the worst. However, the date obtained from formula method could be used as a reference of other methods, which could ensure the correct implementation of others.
