摘要
为了比较准确地预测瓦斯涌出量,文章通过实际掌握正阳煤矿2#煤层的瓦斯基础参数、煤层赋存状况及开采技术条件,采用分源预测法进行对正阳煤矿2#煤层的回采工作面进行瓦斯涌出量预测,按工作面瓦斯主要涌出源对回采工作面的瓦斯涌出量进行计算。
In order to accurately predict the gas emission value from the coal mining face, in combination with the gas basic parameters of No. 2 seam in Zhengyang Mine, the seam deposit and the mining technical conditions, the separated source prediction method was applied to the gas emission value prediction from the coal mining face in No. 2 seam of Zhengyang Mine. According to the main gas emission resources of the coal mining face, the gas emission value from the coal mining face could be calculated.
