摘要
通过分析矿井综放工作面供风实例中上行供风方案存在的问题,并对上行、下行通风方式的可行性进行对比论证,决定采取下行通风方式,对原有工作面通风系统结构进行优化.通过现场验证发现,下行通风方式在工作面降尘、抑制采空区自燃发火等方面存在显著优势,适用效果更优.
Abstract
By analyzing the problems of the upward air supply scheme in the example of mine fully mechanized caving working face,and comparing and demonstrating the feasibility of the upward and downward ventilation methods,it is decided to adopt the downward ventilation method and optimize the structure of the original working face ventilation system.Through on-site verification,it was found that the downward ventilation method has significant advantages in reducing dust in the working face and suppressing spontaneous combustion in the goaf,and its applicability is better.
