【摘要】：山西古交太原某煤矿开采煤层多同时会有大量瓦斯涌出,通过分源预测法对矿井的2~#、3~#、6~#、7~#、8~#、9~#煤层的回采工作面进行数值分析,得到邻近层瓦斯排放率与层间距的关系曲线。通过分源法得到瓦斯涌出量数据和实际值接近,但是仍然存在误差,并分析得出误差产生的原因。
[Abstract]:In a coal mine in Gujiao Taiyuan, Shanxi Province, there will be a large amount of gas emission at the same time. Numerical analysis is carried out on the mining face of coal seam 2, 3, 6, 7, 8 and 9 in the coal seam of coal mine in the coal mine of Gujiao Taiyuan, Shanxi Province, by means of separate source prediction method. The relationship curve between gas discharge rate and interval between adjacent layers is obtained. The gas emission data obtained by separate source method is close to the actual value, but there are still errors, and the causes of the errors are analyzed.
