Application of Self-Drilling Anchor on Coal Gangue Slope Treatment

In the reinforcement of coal gangue slope treatment, it is difficult for hole and construction with traditional method, self-drilling anchor method was adopted, Slope stability safety factor was calculated with slope stability analysis software under coal gangue slope and self-drilled anchor reinforcement coal gangue slope, and finally the anchor pipe processing technology, construction methods and the production of grouting process and framework were introduced, which provided the practice for similar engineering.
