矿井漏风规律与防治技术研究

Study on Mine Air Leakage Law and Prevention and Control Technology

针对矿井漏风引发的通风系统可靠性低、自燃可能性提高等问题,对矿井漏风规律与防治技术进行研究。在对矿井漏风类型及漏风阻力定律进行研究的基础上,找到了矿井内部漏风和外部漏风的有效治理措施。并针对传统风门存在的问题,进行了改进设计。在张家沟煤矿现场应用表明,该措施保证了通风系统的可靠性,漏风量降低一半以上。

In order to solve low reliability of mine ventilation system and high spontaneous combustion possibility problem which caused by air leakage in mine, the law of air leakage and control technology in coal mine was studied. Based on the analysis of the mine air leakage type and mine air leakage resistance law, the internal air leakage and external air leakage of effective control measures were put forward. The air door their existing problems were improved Zhang Jiagou Mine site application showed that the technology ensured the reliability of the ventilation system, reduced more than half of the lower leakage air volum
