Width design for gobs and isolated coal pillars based on overall burst-instability prevention in coal mines

Journal of Rock Mechanics and Geotechnical Engineering, 2016
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 ...

Classification of coal bursting liability of some chinese coals using machine learning methods

Scientific Reports
AbstractThe classification of coal bursting liability (CBL) is essential for the mitigation and management of coal bursts in mining operations. This study establishes an index system for CBL classification, incorporating dynamic fracture duration (DT), elastic strain energy index (WET), bursting energy index (KE), and uniaxial compressive strength (RC).

Exploration and summary of prevention and control of rock burst in steeply inclined and ultra-thick coal seam

Meitan kexue jishu
The roof breaking movement of steeply inclined and ultra-thick coal seam mining is complex, and the evolution law of stress and energy is special. Under the influence of deep ‘three highs and one disturbance’, the prevention and control of rock burst is ...

ROCK BUMP – THE REASON OF METHANE OUT BURST IN THE COAL MINE?

Bulletin of the Kamchatka Regional Association «Educational-Scientific Center». Physical & Mathematical Sciences, 2015
The proposed model presents a rock bump (a technogeneous earthquake) as a shock wave emergence on the inside wall of a mine. In such a case, an unloading, tensile wave is generated which moves in the opposite (into the wall) direction. A shock wave is accompanied by medium motion in the direction of shock wave propagation with the velocity ...
