随着我国新能源政策的持续推进,对规模煤炭资源的开采也更注重科学性、实效性和安全性。特别是针对“长距离、大断面”的大中型煤矿,对其开采要求也更高。为避免瓦斯聚积造成安全隐患,提高挖煤作业舒适度,必须对煤巷道进行通风。本文从长距离通风技术概述入手,探讨全风压与局部通风机相结合的长距离局部通风技术的应用。 With the continuous promotion of China’s new energy policy, the exploitation of large-scale coal resources is also more scientific, effective and safe. Especially for the “long-distance, large section ” large and medium-sized coal mines, the mining requirements are also higher. In order to avoid the safety hazard caused by gas accumulation and improve the comfort of coal mining operation, the coal tunnel must be ventilated. This article starts with an overview of long-distance ventilation technology and discusses the application of long-distance local ventilation technology combining full-pressure and local ventilation.
