Support Scheme Optimization Design for Thick Coal Roof Mining Roadway in Wujiagou Mine
Aiming at the phenomenon of partial roof falling in mining roadway of Wujiagou Mine, base on the study of surrounding rock conditions and reason analysis of roof falling, the support scheme of utilizing extra-long bolt to instead of anchor cable is proposed. The new support scheme have been applied to the practice.
