摘要:
为了采取合理的瓦斯抽采技术,实现矿井安全高效开采,对朱集矿13-1煤瓦斯基本参数进行了现场和实验室测定,得出了瓦斯含量、瓦斯压力、放散初速度,透气性系数、坚固性系数等参数,并对测定结果进行了理论分析,得出了这些参数的基本规律。结果表明:随着开采深度的增加,在一定深度范围内,其瓦斯压力、瓦斯含量呈线性增长,瓦斯压力与瓦斯含量都比较大;煤层钻孔瓦斯衰减系数较大,该煤层的透气性系数较小,D、K值小于其临界值,可判断出该煤层为难抽煤层且有突出危险性。
Abstract:
To accomplish safe and efficient coal mining through appropriate gas extraction technology, the basic parameters of coal and gas of ZhuJi 131 coal mine were determined with field and laboratory measurement. The parameters including gas content, gas pressure, initial relief velocity, permeability coefficient, consistent coefficient and other parameters were measured, and the basic law of these parameters were obtained after theoretically analysis. The results showed that: in a certain range of depth, gas pressure is high and gas content is great, and both increase linearly with the increase of mining depth; the attenuation coefficient of boreholes in coal seam is big and permeability coefficient of the coal seam is small; value of D, K is smaller than the critical value, which determines that the gas drainage is difficult and the coal seam is in danger of outburst.
