阳泉煤业(集团)有限责任公司矿井瓦斯综合治理技术具有国际领先水平,综放面内错尾巷排放瓦斯技术是瓦斯综合治理技术中最重要的技术之一。但是,综放面布置内错尾巷后,采空区自然发火“三带”范围会发生变化,通过研究说明采用内错尾巷的布置形式,只要建立完善的自然发火预测预报制度,综放工作面保持日进2.58m/d以上的推进速度,就可以较好地预防煤层自然发火。
Yangquan Coal Industry (Group) Co., Ltd. mine gas comprehensive management technology has the international advanced level, and the tail gas drainage technology in the fully mechanized caving face is one of the most important technologies in comprehensive gas control technology. However, after the fully mechanized top-coal caving face is arranged inside the tailrace, the gob area will naturally change its scope of “three belts”. Through the study of the layout of the internal staggering tail lanes, as long as the establishment of a perfect natural fire prediction and forecasting system, The fully mechanized top coal caving face maintains the advancing speed of more than 2.58m / d, which can prevent spontaneous combustion of coal seam well.
