摘要

The coal layer's gas permeability coefficient is an important index to judge wether it is easy for the gas drainage. The radial flow method is the most common testing way for the coal layer's gas permeability coefficient calculation the current. However, its calculation process is tedious. And sometime could not find the right calculation formula during the calculation. At times, it turns out two results during the calculation. According to the coal bed gas flow theory, combined with the outlier's processing method, using the VB language to develop a software for the coal layer's gas permeability coefficient. Using this software, it can realize the accurate and rapid calculation for the coal layer's gas permeability coefficient.
