To use the drilled coal core site desorption data can get a drop-down curve of abandoned mine methane emission rate versus time approximately.
用钻孔煤心现场解吸数据可以近似得到废弃矿井甲烷涌出速度对时间的下降曲线。
To integrate the curve of abandoned mine methane emission rate versus time to infinity against time, can get abandoned mine CBM resources at the time of estimating.
对废弃矿井甲烷涌出速度对时间的曲线按时间积分到无穷大，可以得到计算时刻的废弃矿井资源量。
Finally the calculation method and formula of coal methane content and pressure are presented by using the emission rate from broken coal.
最后提出了利用煤屑解吸瓦斯流量测算煤层瓦斯压力和瓦斯含量的计算方法和计算公式。
