矿山循环风的成因与治理措施

Causes and control measures of mine circulating air

针对矿井循环风的问题,通过分析掘进风与矿井通风的关系,介绍不同情况下掘进通风的能量关系;部分通风循环风是由于通风机所在的巷道风量超过通风机的吸风量;掘进过程中巷道的出风口压力超过通风机进风口的压力就容易形成循环风,本文主要根据目前矿山开采过程中的循环风成因进行分析总结,通过模拟和计算对可控循环风的通风效果和稳定性等进行分析总结,并提出相应的治理措施。

Aiming at the problem of circulating air in mine,this paper introduces the energy relationship between tunneling air and mine ventilation by analyzing the relationship between tunneling air and mine ventilation.Pressure is easy to form circulating air.This paper mainly analyzes and summarizes the causes of circulating air in the mining process,analyzes and summarizes the ventilation effect and stability of controllable circulating air through simulation and calculation,and puts forward corresponding control measures.
