通过对突出资料进行统计分析,总结出平煤十二矿煤与瓦斯突出呈带分布,集中分布在己六采区、底板标高-350—-600 m区域和三水平深部。依据矿井实际瓦斯地质资料,运用瓦斯地质理论,分析了各区域内煤与瓦斯突出发生的主要原因:地质构造、煤层厚度变化与倾角变化、煤层埋深分别为己六采区、底板标高-350—-600 m区域和三水平深部区域内煤与瓦斯突出的主控因素,控制着各区域内突出的发生和分布规律,此结论为防治煤与瓦斯突出提供了理论依据。

With the statistic analysis conducted on the outburst information, the paper summarized that the coal and gas outbursts in Pingmei No. 12 Mine distribut ed in zones and were concentrated and distributed in Ji- 6 Mining Block, the areas with a floor elevation of- 350-- 600 m and the deep section of Three Level. Accordin g to the actual gas geological information and with application of the gas geological theory, the main causes of the coal and gas outburst occurred within each area wer e analyzed, the geological structure, the seam thickness variation and the inclination variation as well as the seam depth would respectively be the main control factors of the coal and gas outburst within Ji- 6 Mining Block, the area with a floor elevation of- 350- - 600 m deep section of Three Level, would control the occurrence and dis tribution law of the outburst occurred in each area and could provide theoretical basis to prevent the coal and gas outburst.
