摘要
为了能更加科学而准确地评价矿井通风难易程度,分析了目前煤矿利用等积孔评价矿井通风难易程度失效的主要原因。结合缪尔格法评价矿井通风难易程度、通风系统风量与矿井通风阻力的关系,提出了准确划分现代矿井通风难易程度的新方法,并在不同类型矿井验证了新的评价方法的准确性和合理性。结果表明,新的矿井通风难易程度划分方法能更准确而合理地对矿井通风难易程度进行界定。
In order to evaluate the difficulty of mine ventilation more scientifically and accurately,the main reasons for the failure of the current coal mines to evaluate the difficulty of mine ventilation using isocratic holes are analyzed.Combining with the Muirger method to evaluate the difficulty of mine ventilation,the relationship between the air volume of the ventilation system and the resistance of mine ventilation,a new method for accurately dividing the difficulty of modern mine ventilation is proposed,and the accuracy of the new evaluation method are verified in different types of mines.The results show that the new method of dividing the difficulty of mine ventilation can more accurately and reasonably define the difficulty of mine ventilation.
