摘要
矿井通风难易程度采用矿井等积孔的大小进行评估,但不能准确反映其真实的难易程度。应以矿井总风量能否满足需要为前提,结合井下各用风区域的风量调配的难易,同时用等积孔衡量时,还需考虑瓦斯涌出量的大小、矿井开采强度、采煤方法等因素的影响,进行综合评算。
Mine ventilation Difficulty Level is assessed by the size of Mine pit equivalence hole, which can not accurately reflect the Difficulty Level. We should make whether the total amount of wind can meets the the mine＇s need as the premise, Combined the difficulty of the deployment of regional wind underground, at the same, when measured with the equivalence hole, we must consider the amount of gas emission, the mine mining strength, the mining method and so on, assess comprehensivly.
