【摘要】 基于张集矿煤田地质勘探资料,结合矿井生产中测定的各项煤层瓦斯参数,从地质的角度分析了煤与瓦斯突出的控制因素。张集矿迄今所发生的煤与瓦斯突出动力现象多是受地质构造影响,是以地应力为主导因素的突出。该矿煤与瓦斯突出的危险程度随着煤的变质程度的增高而增大,构造煤发育的地区往往是煤与瓦斯突出危险程度较大的地区。煤的厚度越大、煤厚变化程度越大的地区煤与瓦斯突出危险程度越大。煤层顶板岩层为泥岩、炭质泥岩、粉砂岩时煤与瓦斯突出危险程度较大。更多还原

【Abstract】 The paper discusses the analysis of according to the data collected from the original geology and the gas parameter of Zhangji mine,coal and gas outburst from the geology’s point of view,and to make sure that the control factors of the coal and gas outburst are the geology construction effect. The coal and gas outburst of Zhangji mine became more and more dangerous due to the increasingly higher metamorphoses degree.The tectonic coal developed areas is more dangerous than other areas.The coal and gas outburst became more and more dangerous along with the thickness of coal seam changing and increasing.The above conclusions lay the foundation for forecasting the area of coal and gas outburst and guiding the safe production of Zhangji mine.更多还原
