在矿井通风工程中,空气密度是一个非常重要的参数,广泛应用于矿井通风阻力测定、自然风压计算、通风机性能测试等技术环节。但这个参数不能直接测量出来,通常都是利用精密气压计测试大气压力,利用干湿球温度计读取干球温度和湿球温度,然后人工经过两次查表求得密度值。手工查表不但费时费力,而且极易出错,尤其对上百条数据,这种方法显得力不从心。因此开发软件快速计算密度值有着一定的实用价值。井下湿空气地面大气在通风动力装置的作用下,沿着通风路线进入矿
In mine ventilation engineering, air density is a very important parameter and is widely used in mine ventilation resistance measurement, natural wind pressure calculation, fan performance testing and other technical aspects. However, this parameter can not be measured directly, usually using the precision barometer to test the atmospheric pressure. The dry and wet bulb thermometers are used to read the dry and wet bulb temperatures, and the density is obtained manually after two lookups. Manual look-up table not only time-consuming and laborious, but also extremely error-prone, especially for hundreds of data, this method seems powerless. Therefore, the development of software to quickly calculate the density value has a certain practical value. Downhole wet air ground air under the action of the ventilating power plant, along the ventilation route into the mine
