Abstract:Through experimental study of hydraulic cutting seam drainage methane indoor about big coal sample , phenomenon of coal and gas burst in the process of hydraulic cutting seam is brought to light. According to the character of coal, the stress state, the stress lever, the stress pressure water-jet ,the pressure of gas etc, along with result of numerical computing ,the mechanism of coal and gas burst in the process of hydraulic cutting seam is analyzed.
Keywords:hydraulic cutting seam  water-jet  experiment  coal and gas burst  numerical simulation
