Abstract

The accuracy of gas content determination results plays an important role for coal mining and the evaluation of coal seam methane reserves. The common sampling ways are described mainly to measure gas content directly in underground coal mine. Through the analysis for common sampling ways of direct gas content determination in actual underground production, these main influence factors are found out about the corresponding sampling ways for coal seam gas content measurement results. Based on the comprehensive consideration of main influence factors, the sampling way of gas content determination is tried to find, it is more reliable, more simple, and its determination result is more accurate.
- gas content,
- direct method,
- sampling way,
- influence factor,
- solution
