摘要
Abstract
In order to make sure the influence of harmful gas and spontaneous combustion in small kilns on working face at nearly vertical super high seam,we construct probe holes in kilns during the period of tunneling of air intake and return roadway and mining.According to the gas analysis results of manual detection and sampling analysis,at the same time,considering the effect of blasting at working face,we accurately analyze gas status and ignition situation in kilns,and determine the influence degree of kilns on working face.关键词
