摘要
为了减少宏阳矿业12煤层12102工作面瓦斯聚集,研究了沿空留巷上下顺槽进风、留巷回风道回风形式的下行式“Y”型通风技术。结果表明:采用下行式“Y”型通风技术,实施合理的安全措施,可以在消除工作面隅角瓦斯积聚、通风路径长、风阻高等问题的同时,控制好工作面漏风问题,保障工作面安全工作环境。
In order to reduce gas accumulation in the 12102 working face of No.12 coal seam in Hongyang Mining,and eliminate fire hazards,the downward"Y"type ventilation technology of gob side entry retaining in the form of"two in and one return"was studied.The results show that the downward"Y"type ventilation technology and the implementation of reasonable safety measures can eliminate the problems of gas accumulation,long ventilation path and high wind resistance in the upper corner of the working face,control the air leakage in the working face,and ensure the safe working environment of the working face.
