掘进工作面大断面超长距离通风技术是减少煤尘、瓦斯等爆炸事故,保证采区安全生产的一项重要技术措施。掘进工作面中的大断面和超长距离这两种因素给通风带来了很大的困难,是煤层开采中急需要解决的难题。本文对掘进工作面大断面超长距离通风技术进行了相应的研究分析和探讨。 Tunneling large cross-section ultra-long distance ventilation technology is to reduce coal dust, gas and other explosions, to ensure mining safety production is an important technical measure. Both the large cross-section and the long distance in the driving face have brought great difficulties to the ventilation and are the urgent problems to be solved in the coal seam mining. This paper carries out the corresponding research and analysis on the ventilation technology of large cross-section of longwall face.
