兴隆庄煤矿3＃煤自燃倾向性研究

Study on Spontaneous Combustibilit y of No.3Coal Seam in Xinglongzhuang Mine

从理论上讲,煤自燃倾向性即煤的氧化性应该稳定不变可重复测试,但实际条件下并非如此,煤层自燃倾向不仅与煤自身化学结构有关,而且与煤层所处的周围环境有关。通过模拟现场煤层所处条件,测试研究了兴隆庄3#煤自燃倾向性。

In view from theory,the spontaneous combustibility of coal ,namely the o xidization of coal,should be constant and re -measurable,but it i s not always the case under actual conditions.The spontaneous combustion of coal seams is not only related to the chemical stru cture of coal itself,but also to the surrounding environment where c oal seams are located.In this paper,measurement was made on the sp ontaneous combustibility of No.3coal seam in Xinglongzhuang Coal Mine by simulating the site conditions of this coal seam.
