摘　　要：开展对热害矿井的治理,基础工作是对矿井巷道周围的温度分布进行掌握,其中又以围岩调热圈的研究最为重要。本文对井巷围岩调热圈及围岩在通风条件下的散热规律进行了分析,建立了相应的数学模型来推导调热圈半径和温度场;以三河尖矿的巷道围岩调热圈为具体实例,对影响围岩调热圈半径及边界大小的若干个物理参数进行了研究。结果表明:不同区域内的调热圈半径不同,其中其半径的形成与通风时间因素的影响最为密切。测试的结果对该高温深井进行通风量控制以及热害防治有指导意义。To carry out the management of the mine having heat damage,the basic work is to control the temperature distribution around the roadway and the study on temperature distribution of heat adjustment circle of wall rock in roadway is especially the most important part.In this paper,the heat adjustment circle of wall rock in roadway and heat dissipation law under ventilation condition are analyzed and the corresponding mathematical model is established to deduce the radius and temperature field of the heat adjustment circle.The heat adjustment circle of Sanhejian Mine is taken as the application example,thus some physical parameters affecting the radius and boundary of the heat adjustment circle are studied.The results of the test have a guiding significance in the ventilation control and prevention of heat damage of high temperature and deep well.
