helium%argon and its isotope%stress emanation%prediction of gas outburst%contour map%engineering geology
In the Yutianbao Mine, the Nantong Coal Field, Chongqing, a lot of gas samples were measured and analyzed. It has been found in these samples that helium is sensitive to stress concentration, while argon is sensitive to stress release. Compared with the flowing out of gas itself, the combination of helium and argon can be more suitably used as an indicator to predict gas outburst. In a mining area of this mine, both δ He > 30 and δAr < δ0.97 can be used critically to define the dangerous area. Also, the contour maps of δ He, δ Ar and CH4 can provide a guidance for engineering monitoring.
