结合以前郭家河煤矿工作面防灭火的经验,从工艺方面入手,在撤架期间对1305特厚综放工作面进回风两道布置方式进行改进,避免了撤架期间支架后尾梁上方破碎煤体氧化自燃问题,并减少了采空区遗煤量。通过对比1303工作面撤架期间防灭火数据,体现了1305工作面防灭火措施的优越性,使得1305工作面撤架更加安全顺利进行。
Combining with the experience of fire prevention and extinguishing in the former Guojiahe coal mine face, from the aspect of technology, the two ways of arrangement of inlet and return air of 1305 ultra-thick mechanized coal caving face were improved during the period of withdrawal, avoiding the broken coal above the tail beam Oxidation of the body of the problem, and reduce the amount of coal left in the mined area. By comparing the data of fire prevention and extinguishing during the period of removing support of 1303 face, it shows the superiority of fire prevention and extinguishment measures of 1305 working face, which makes the lifting of the 1305 face more safe and smooth.
