在毛主席无产阶级革命路线指引下,我国煤炭工业飞速发展,矿井不断向深部延伸,因此,地温随之上升,这必将导致深部开采时,采掘工作面气温较高,气象条件不良。因此,在矿井深水平未投产之前,有必要预先计算出深水平采掘工作面的空气温度,以选择合理的空调措施,保证深部开采的正常进行。为此,需要对深部矿井风流热力状况进行汁算。根据几年来对淮南九龙岗 Guided by Chairman Mao’s proletarian revolutionary line, the coal industry in our country is developing rapidly and the mine extends to the deep. As a result, the ground temperature rises, which will inevitably lead to the deep mining and the high temperature of the mining face and poor weather conditions. Therefore, it is necessary to calculate the air temperature of the deep horizontal mining face before the deep mine is put into operation, so as to select reasonable air-conditioning measures and ensure the normal operation of deep mining. To do this, we need to calculate the thermal status of the wind flow in deep mines. According to several years of Huainan Jiulonggang
