煤矿安全规程(以下简称“规程”)109条规定:矿井所需风量可按相对瓦斯涌出量计算。对于低沼气矿井(相对沼气涌出量为10米~3及其以下的矿井),日产一吨煤所需风量为1.00～1.25米~3/分。采区和工作面所需风量也是按这一原则计算的。但是,这种计算方法存在着一个明显的问题,即风量与产量的一次方成正比,产量增加一倍时风量电要增加一倍。炮采工作面的产量不大,这种计算方法具有一定的综合代表性,是可行的,也是合理的。而综采工作而,一般产量很大,这种计算配风量的办法就有问题了。比如,徐州夹河矿2409综采工作面,平均日
Coal Mine Safety Regulations (hereinafter referred to as the “Regulations”) 109 provides that the required air volume of mine can be calculated according to the relative gas emission. For low biogas mines (with a relative biogas output of 10 to 3 m and below), the required air volume per tonne of coal per day is 1.00 to 1.25 m 3 / min. The amount of air required for the area and face is also calculated on this principle. However, there is an obvious problem with this method of calculation, that is, the air volume is proportional to the first-order output and the air volume is doubled when the output is doubled. Production of artillery mining face is not large, this method of calculation has a certain degree of comprehensive representation, it is feasible and reasonable. The fully mechanized mining work, the general production is very large, this method of calculating the amount of air with a problem. For example, 2409 fully mechanized coal face in Xuzhou Jiahe Mine, the average day
