固隆煤业1309进风顺槽掘进工作面通风设计

Ventilation design of 1309 intake crossheading heading face in Gulong Coal Industry

为解决大断面煤巷快速掘进的通风难题,本文以固隆煤业1309进风顺槽掘进工作面为研究对象,对掘进巷道的通风量进行分析计算,并据此对局部通风机进行选型。实践表明,经过科学的风量计算、合理的风机选型和严格管理,保障了固隆煤业1309进风顺槽掘进工作面的通风安全,巷道在掘进期间未发生通风事故,未出现瓦斯超限,为安全高效掘进提供了保障。

In order to solve the ventilation problem of rapid excavation of large cross-section coal roadway,this paper takes the 1309 intake crossheading excavation face of Gulong Coal Industry as the research object,analyzes and calculates the ventilation volume of the excavation roadway,and selects the local ventilator accordingly.The practice shows that through scientific air volume calculation,reasonable fan selection and strict management,the ventilation safety of 1309 intake crossheading heading face in Gulong Coal Industry has been guaranteed is realized.There is no ventilation accident and gas overrun in the roadway during tunneling,which provides a guarantee for safe and efficient tunneling.
