Abstract: Based on the background of muduchaideng mine in Inner Mongolia and Shaanxi base, the monitoring data of ground pressure in the process of stopping and resuming mining of long and large working face are analyzed, and the law of ground pressure behavior before and after stopping and resuming mining is studied. Finally, the key technologies of rock burst prevention and control in the process of stopping and resuming mining are summarized. It shows that: before and after stoppage, the energy and frequency of microseismic time significantly reduces, and the data of coal seam stress and support resistance significantly increases; the activity intensity of vibration field goes through sudden increase to decrease and finally to small increase; the first 40 knives (about 35m) in the initial stage of remining are the key areas for rock burst prevention and control; In on-site dangerours area, the workflow of "early warning, drilling and inspection confirmation of dangerous situation, pressure and danger relief, effect verification" works well ; the key measures for rock burst prevention and control in the process of stopping and resuming mining are conclueded, which provides guidance for the prevention and treatment of rock burst in mining face with similar conditions in n Inner Mongolia and Shaanxi base.
