Research and engineering practice on mechanical reaming for pressure relief and rock burst prevention technology in hard coal seam roadways

Abstract Coal seam drilling for pressure relief is one of the most widely adopted measures to mitigate rock bursts. However, conventional drilling methods exhibit limited effectiveness in hard coal seams and may compromise the integrity of roadway support structures. To optimize traditional pressure...
