摘要: 为了能够准确掌握矿井巷道在一个完整通风周期内的围岩的温度变化情况并以此为基础对其进行经济性评价研究;首先以傅里叶导热定律为基础,采用Abaqus软件建立数值模型并利用有限元方法对巷道围岩与空气热交换过程以及巷道内部的围岩温度分布进行了求解研究,获得了巷道围岩对冷、热量的存储量大小及存储规律;之后利用等效空调方法对巷道围岩调热能力进行了经济性评价。结果表明:矿井围岩调热圈具有较大的经济优势,未来可以进一步尝试进行工程实践。Abstract: In order to accurately grasp the temperature change of surrounding rock in a full cycle of ventilation in the mine tunnel and do economic evaluation studies on it on this basis, in this paper, based on Fourier heat conduction law, the numerical model was established by Abaqus software and the finite element method was used to study the process of surrounding rock and air heat exchange and the temperature distribution of surrounding rock in the tunnel, the amount of cold and heat storage and the storage law of the surrounding rock of roadway were obtained. After that, the economical evaluation of the heat transfer capability of surrounding rock was carried out by using the equivalent air conditioning method. The results show that the surrounding rock of the mine has great economic advantages, and can further try to carry out the engineering practice in the future.
