Stress Distribution of Coal and Rock in Large Mining Height Disturbed Zone

Taking occurrence characteristics of coal and rock in excavation disturbed zone of Ningdong Mine 6.2 m height mining face as the background, by using numerical simulation and field monitoring method, the article researched coal and rock stress variation characteristics under the environment of large mining height disturbed zone (main transport roadway), and analyzed and summarized stress at face ends and lateral stress distribution of coal pillar at main transport roadway.
