Based on theory of inertial points a new assessment method of back calculation of modulus is put forward with the assessment criterion provided.

基于惰性点理论，提出了一种新的模量反算判别方法，并给出了判别标准。

Gas content of 14 points in Gaocheng Colliery was calculated with back calculation formula which may be used after 0.6 was multiplied to it as modification.

利用瓦斯涌出量反算公式，计算了告成矿14个瓦斯含量点，通过与实测数据比较，乘以0.6的系数校正后可以使用。
