文中对煤层气资源量计算中的几个问题作了探讨，指出煤层气资源量中的甲烷量是我们计算储量的主要对象，煤层围岩及不可采煤层中的气体应得到重视，计算储量时可采用数值模拟法放入开发阶段的储量动态模拟之中
In this paper, some problems in the calculation of CBM resources are discussed. It is pointed out that the amount of methane in the CBM resources is the main target of our calculation. The gas in coal seam surrounding rock and unfeasible coal seam should be taken seriously. Can be used to simulate the amount of time into the development phase of the dynamic simulation of reserves
