Rock burst risk evaluation based on equivalent surrounding rock strength
International Journal of Mining Science and Technology, 2019 On-site investigations consistently show that the rock burst inherent to coal seams varies greatly with coal seam thickness. In this study, impact factors related to coal seam thickness and surrounding rock strength were analyzed and a corresponding rock
