高瓦斯易燃煤层长距离大断面掘进期间局部通风技术管理实践

Local Ventilation Technology Management Practices of High Gas Flammability Seam during Long-distance and Big-section Tunneling

介绍了复杂地质构造、高瓦斯、易燃煤层条件下局部通风管路技术,以大水头煤矿东108回风顺槽西段掘进工作面长距离局部通风为例,针对局部通风工作中存在的诸多问题,提出并实施了一系列技术改进措施,并对经济效益和推广前景进行了认真分析。

The local exhaust ventilation pipe technology under the complex geological structure, high gas, flammable coal conditions is introduced. Taking local ventilation of Dashuitou Coal Mine east-108 return air trough western section tunneling face for example, based on many problems in local ventilation, a series of technical improvements are proposed and implemented, and a careful analysis on the economic and promotion prospects is conducted.
