按炸药量计算压入式通风掘进工作面需风量的方法探讨

Discussion on required air volume calculated by explosive charge at driving face with forced-ventilation

针对现行按炸药量计算煤矿掘进工作面需风量的标准进行了分析研究,指出现执行计算标准存在的差别,提出符合现场实际的标准改进建议。在现场经实际应用,按新方法依据炸药量配备的风量可以满足掘进工作面风量的调配要求。

After the analysis on current standards about required air volume calculated by ex-plosive charge at driving face,it was found that the differences existed in the implementation.So the proposals for improvement were proposed to agree with the actual situation.The practice showed that the air volume input according to new method could meet the requirements of air vol-ume for driving face.
