摘要
为了科学准确地评价基建矿井的通风难易程度,本文在通过对煤矿生产矿井通风难易程度常用的等积孔分析,并借鉴其评价方法,结合矿井基本建设的通风特点,把矿井总风量划分为2个等级,以反映不同矿井的通风难易程度。可以有效地解决了评价现阶段矿井开拓的通风难易程度评估的难题。
In order to accurately evaluation the developing coal mine of ventilation difficulty degree,Based on Characteristic of the developing coal mine of ventilation,divided into two grades with the new method.Each grade could reset the size of the equivalent orifice in order to reflect the ventilation difficulty degree.The results showed that the new standard could be effective to solve the evaluation on difficult problems for the ventilation of developing coal mine with high ventilation volume at present.
