Abstract: Anchoring through the use of underground mining, which is more common 715.24 mm anchor beam as the prototype, Multiple ordinary prestressed cable pullout failure test was conducted in deep (+640 ~ +700 m the middle) of the Maluping mining field test site. Comparative analysis findings of Each rock bolt load deflection curve, failure mode and failure of anchorage length、cable network rock strength and other factors on the performance were obtained. It provides a reliable experimental basis of Underground Support Project for Maluping mine.

Key words: Prestressed anchor, Side resistance testing
