Stability Control of Surrounding Rock of Driving toward Strong Disturbance in Roadways of Xinshun Coal Industry
To solve the severe deformation of surrounding rock and difficult supporting during the gob-side driving process,this paper takes a track gateway in Xinshun Coal Industry of Shanxi Coal Import and Export Group as the research object.This study used borehole peeping and nu-merical simulation to study the stability control of the surrounding rock in driving toward strong disturbance in the roadways.The support plan for the roadway was designed as the combined support method of anchor bolts+anchor cables+anchor nets as well as the W-shaped steel belts.After on-site application,the surrounding rock deformation was monitored.The results showed that the supporting measures effectively inhibited the surrounding rock deformation and achieved good support effects.
