Abstract：Based on the desorption experiments of many coal samples taking from some typical coal mining areas in our country, a nonlinear surface model for quick gas content measurement was established and the quick gas content measurement instrument and parameter correction instrument were developed by using theoretical analysis and nonlinear regression method. The results showed that a highly nonlinear surface relationship existed among the desorption characteristic parameter value a, i and the gas content W. The nonlinear surface model for quick gas content measurement can well describe the relationship among parameter value a, i and the gas content W. The coal-seam gas content can be quickly measured in 20min by the quick gas content measurement instrument, the measuring error of the instrument was less than 10% and its performance was better than that of the similar products both at home and abroad. This quick gas content measurement instrument can meet the requirement of gas content measurement in projects.
