Analysis of Resistance Measurement and Optimization Scheme of Ventilation System

本文以某矿作为研究对象,根据该矿的具体情况,制定了详细的通风阻力测定方案,对该矿的进、回风巷的通风阻力进行全面测定,并实测该矿的有效风量率为81%,低于相关规定的要求,根据该矿的实际情况制定了有效的优化方案。通过对该矿通风系统的优化,将该矿的有效漏风率提高至90%,并且降低了该矿的通风阻力值达300Pa,从而保障了该矿的通风系统的稳定性。

Taking a mine as the research object,according to the specific situation of the mine,this paper formulates a detailed ventilation resistance measurement scheme,and makes a comprehensive measurement of the ventilation resistance of the mine's entry and return air lanes.The effective air flow rate of the mine is 81%,which is lower than the requirements of relevant regulations.According to the actual situation of the mine,an effective optimization scheme has been worked out.By optimizing the ventilation system of the mine,the effective air leakage rate of the mine is increased to 90%,and the ventilation resistance value of the mine is reduced to 300Pa,thus ensuring the stability of the ventilation system of the mine.
