摘要

The sixth producing area of the No.1 well field in the Yaojie Coalmine of Gansu is a gas outburst coal mine. The gas is dominantly composed of carbon dioxide mixed with the methane. Based on the analysis and comparison of the gas from the drills in the stage of exploration and from the second coal bed during mining, tied with the gas nature from the adjacent well field, this paper summarizes the preservation, relative emission mass of gas and their linkage to the geological factors. This should be used to forecast gas outburst and prevent the coal and carbon oxide outburst during mining.
