Forecasting Method of Coal and Gas Outburst Based on KPCA-SVM
Gong-kuang zidonghua, 2010 The paper proposed a forecasting method of coal and gas outburst based on KPCA-SVM. The method firstly used KPCA to select features of correlative indexes influencing coal and gas outburst, then used SVM to make classified forecasting coal and gas ...

The Coordinated Mining Technology of Coal and Gas in Outburst Coal Seams
Shock and VibrationWith the increase of mining depth, the gas management problem in coal and gas outburst mine is more prominent. At the same time, gas is used as a clean resource to mine together with coal which is to realize the simultaneous extraction of coal and gas more practical significance.
