Width design for gobs and isolated coal pillars based on overall burst-instability prevention in coal mines
An investigation was conducted on the overall burst-instability of isolated coal pillars by means of the possibility index diagnosis method (PIDM). First, the abutment pressure calculation model of the gob in side direction was established to derive the abutment pressure distribution curve of the is...
