摘要
斯派尔煤矿属于高瓦斯矿井,受复杂地质构造条件的影响,容易发生瓦斯动力现象。采用现场和实验室实测的方法,确定了影响斯派尔矿瓦斯动力现象的主要因素为煤的坚固性系数偏低、煤厚变化较大和存在大的地质构造,为实现斯派尔矿瓦斯动力现象的针对性预防提供可靠依据。
Sipaier coalmine belongs to high gas mine, with complicated geological structure conditions, easily leading to gas dynamic phenomenon ~ According to the field and laboratory measurement, the main affecting factors of gas dynamic phenomenon in Sipaier coalmine are confirmed as low coal firmness coefficient, the change of coal thickness and the large geological structure. Research provides retiahle basis for the accurate prediction and the e- liminate controll of gas dynamic phenomenon in Sipaier coalmine.
