分析了新疆准东二号矿井平均厚度53 m的巨厚自燃煤层的自燃危险性,结合分层放顶煤工作面巷道布置、开采工艺和通风系统能力等条件下可能出现的自燃特点,参考类似条件煤层和矿井开采应用的自燃防治技术,对适用的自燃防治技术和方法进行了探讨。
This paper analyzes the danger of spontaneous combustion of the thick and thick spontaneous combustion coal seam with an average thickness of 53 m in quasi-Dong 2 coal mine in Xinjiang. Combining with the characteristics of spontaneous combustion that may appear under the conditions of tunnel layout, mining technology and ventilation system in strata- Conditions of spontaneous combustion coal seam mining and application of prevention and control technology, the applicable spontaneous combustion prevention and control technology and methods are discussed.
