随着煤炭工业的飞速发展,矿井必然要逐年向深部延深,地温也必然随之上升。就九龙岗矿的实测资料表明,矿井每延深约110米地温要升高2℃,当然各地的地温随深度的递增情况是不尽相同的。需要指出,造成矿井高温的原因,不仅是由于矿井开采深,地温升高所致,而且,井下煤炭、岩石以及有机物质的氧化,坑木的腐烂,空气的下流受压,矿井的高温水,地面气温,机械及电气设备的放热,矿井照明,工人劳动等都对矿井空气有加温作用。尤其随着煤矿综合机械化的发展,大型机电设备的应用,采掘速
With the rapid development of the coal industry, the mine is bound to be deepened to the depth of the year, the ground temperature will inevitably rise. According to the measured data of Jiulonggang Mine, the ground temperature of about 110 meters for every extension of the mine is increased by 2 ℃. Of course, the ground temperature increases with depth as the situation is different. It should be pointed out that the reason for the high temperature in mines is not only due to the deep mining and the rise in ground temperature, but also the oxidation of underground coal, rock and organic matter, the decay of pits, the pressure of the air, the high temperature water , The surface temperature, the heat of mechanical and electrical equipment, mine lighting, workers’ labor and so on have a warming effect on the mine air. Especially with the development of comprehensive mechanization of coal mines, the application of large-scale mechanical and electrical equipment, mining speed
