摘要
采用室内自然解吸法计算了煤层原始瓦斯含量,并根据地质资料和实测数据分析了25031工作面的瓦斯赋存规律。结果表明,25031工作面附近的煤层原始瓦斯含量离散性较大,主要在7.2~14.75 m^(3)/t之间;25031工作面的煤层厚度与原始瓦斯含量的线性拟合较差,煤层埋藏深度与原始瓦斯含量的线性拟合较好;煤层埋藏深度和地质构造是影响25031工作面瓦斯赋存的主要因素。
The original gas content of coal seam was calculated by indoor natural desorption method,and the gas occurrence law of 25031 working face was analyzed according to geological data and measured data.The results show that the original gas content of coal seam near 25031 working face is relatively discrete,mainly between 7.2~14.75 m^(3)/t;the linear fitting between coal seam thickness and original gas content of 25031 working face is poor,and the linear fitting between coal seam burial depth and original gas content is good.The buried depth of coal seam and geological structure are the main factors affecting the gas occurrence of 25031 working face.
