摘要
鉴于山西汾西矿业(集团)有限责任公司柳湾煤矿周边小煤窑开采破坏十分严重,火灾频发,对现有煤层群的开采造成严重干扰的问题,针对五盘区漏风情况,采用理论分析、数学建模、现场实测与计算模拟等方法研究五盘区漏风量、漏风流场及漏风情况随探火巷压力变化而变化等情况,得出五盘区整体漏风情况与烟气可能溢出的位置,指导现场准确判定火源位置与发展状况。
Aiming at the problem that small coal kilns around Liuwan Coal Mine of Shanxi Fenxi Mining(Group)Co.,Ltd.,are seriously damaged,causing frequent fires and causing serious interference on the mining of existing coal seam groups,this paper adopted the theory for the air leakage in Wupan District,mathematical modeling,field measurement and calculation simulation methods to study the air leakage volume,air leakage flow field and changes of air leakage with the pressure change of the fire detection lane in Wupan District,and drew the overall air leakage and the possible smoke overflow location in Wupan District,so as to guide the site to accurately determine the fire source location and development status.
