预防风流逆转 避免突出事故扩大化

Preventing Airflow Reversal and Avoiding Outburst Accident Expansion

煤与瓦斯突出是煤矿安全生产的重大威胁之一,众多研究工作者和企业管理人员做了大量的研究与实践工作,取得了显著的成果。但想要完全防止事故的发生,在现有的技术条件下是不容易做到的,如果通过一定的技术手段,可以人为地控制灾害的影响范围,使事故损失尽量减小,对企业和个人都有重大的意义。阐述了改善矿井通风系统,防止风流逆转带来的灾区扩大化理念,以鹤煤六矿为例,证实了矿井通风系统的优化对防止事故扩大化起到了至关重要的作用。

Coal and gas outburst is a major threat to mine safety and production.A number of research workers and managers have done a lot of research and practical work,which achieved remarkable success.But on the technology conditions in existence,to prevent the occurrence of the accident completely is not easy.If some technical means are taken,the scope of the accident can be controlled factitiously,it will minimize loss of disasters.This has significant meaning for mining company and individuals.This paper described the concept that improving mine ventilation system to prevent the areas of disaster caused by reversed airflow to be enlarged.The examples of Hebi No.6 Coal Mine in Henan Coal and Chemical Industry Group Co.,Ltd.can confirm that the optimization of mine ventilation system played a considerable effect to prevent the accident enlargement.
