摘要
采用井下钻屑解吸法对大东庄煤矿4#煤层的瓦斯含量进行了实测,根据瓦斯含量测值和组分确定了4#煤层处于瓦斯风化带中的氮气带。依据煤层瓦斯风化带下限瓦斯涌出量指标对4#煤层相对瓦斯涌出量和绝对瓦斯涌出量进行预测,得知大东庄煤矿4#煤层属于低瓦斯矿井。
The undergraound gas content of 4 coal seam in Dadongzhuang drilling absorption. Based on the gas content determined that the 4 coal seam located in the N2 strip to the low limit index of the gas mission quantity in Coal Mine was measured by and its components, it was of the gas weathering zone. According the weathering zone, the relative gas emission quantity and absolute gas emission quantity are predicted. At last, a conclusion that Dadongzhuang Coal Mine was a low gas mine was obtained.
