Grey Relevancy Analysis Method Applied to Index Optimization of Outburst Forecast when a Cross-cut is Uncovered

摘要：

In this paper, the coal samples are collected by drilling in situ, and two indexes of outburst forecast when a cross-cut is uncovered-general index and expansion energy in initial released gas, is tested in laboratory, according to grey relevancy analysis method, indexes are optimized, we find that expansion energy in initial released gas is the best index of outburst forecast when a cross-cut is uncovered in MaJiaGou mine.
