Application of monitoring and controlling coal bumps techniques in the deep workface of Kailuan mining area

In order to realize effective monitoring and control of coal bumps in Kailuan mining area,this article constructed multistage mine-panel-working face-local area coal bumps monitoring and control system with information feedback and continuous optimization on the basis of grasping the dominant factors of Kailuan mining area,by summarizing experience in the process of coal bumps control practice in Kailuan mining area and reference of both domestic and foreign advanced coal bumps control technology.And based on the actual geological structure and mining situation of Kailuan mining area,the suitable control technology for Kailuan deep mining coal seams was put forward,including optimization of mining design and the regional technical measures of protective layer mining,combining with local pressure relief measures based on the defects method and supporting measures to improve the local stress environment.
