Influence of mine shallow roadway on airflow temperature

With the increase of the depth of mining, the working environment of deep well is worse; in order to improve the working environment of deep mine, on the basis of a lot of practice, the idea of adjusting the temperature of the air flow in the mine was put forward. Take Jiaodong area as an example, on the basis of the model of surface temperature variation, the influence of surface temperature on the temperature of the mine has been established, obtaining the influence of surface temperature on the shallow layer of the mine area. In assumption of the roadway, the heat exchange process of the surrounding rock and the air flow in the shallow layer of the different seasons was analyzed, a model of the relationship between the geometry size of the roadway and the air temperature change was established, in order to control the temperature of the mine into the air temperature by using the shallow tunnel temperature effect and then to improve the working environment of the mine working environment to lay a theoretical foundation.
