Description
Yongqin Xie leads a team studying sudden rock bursts in a lone coal face inside a fold zone, in a 2026 paper. Deep folds pack stress into the rock, and a lone face with thick coal above it faces high burst risk. Bursts can wreck a mine in seconds.
The team combined theory, computer models, and field data from one mine. They found the rock layers above the face form a long F-shaped frame whose overhang drives peak stress in front of the face very high. Static load plus shock from the frame cracking pushed the coal past its limit. A new warning model joined six quake-based signals with set weights. Its accuracy rose from about 81 percent to about 95 percent in field checks.
