Abstract

Based on the characteristics of the deep large cross-section rock tunnel, inclined empty wedgy cutting technique, mechanized working line composing of full-hydraulic excavating drill-camel and loader buckets, secondary bolt/shotcreting support technique are proposed. These techniques effectively solve the problems of small footage in the rock tunnel, slow transferring rate and the unstable support in the deep tunnel. The shaping quality is improved; the time of working procedure is shortened and the driving speed is boosted.
