| 摘 要： | 钻屑解吸法测定煤层瓦斯含量1-2],具有周期长、误差大、误时误工等缺点,不能满足实际需要。文章以各类煤模拟测试数据为基础,通过运用EXCEL、MATLABE等软件回归分析处理,研究得到煤层瓦斯含量快速计算新公式。通过实验室和现场验证,在利用新建立公式推算煤层的瓦斯含量时,误差小于10%,并且整个过程在15 min内完成,实现了煤层瓦斯含量井下现场快速测定。

| Abstract: | It has the defects of a long cycle,big error and loss of working time when determine gas content by the cinder desorption method,it can not meet the actual needs.Based on various coals simulation calculating data,analysis using by EXCEL and MATLABE software,set up a new formula,it could calculat the gas content in the coal quckly and accurately.Through laboratory and locale experiment,when calculate the gas content in the coal using the new formula,the errors less than 10%.;and the whole process can be completed within 15 minutes,achieve the goal of calculating the gas content in the underground coal seam rapidly. |

| Keywords: | gas content gas desorption law method of calculating gas content rapidly formula of calculating gas content error |
