Abstract

The tunnelling shield (1) for mine galleries, is made up of sections (3, 4, 5, 6, 7) which seem in cross section, form an arch. Each section dovetails into one another at the joints (10) so as to form a rigid assembly. Each section has a cutting edge around part of its periphery to form a complete cutting surface. Each section is fitted with at least one advancing piston and cylinder, these being located at the longitudinal joints (13 etc.), and overlapping these joints. The rearmost set of sections incorporate latching arrangements at the dovetail joints to act as anchorages against the sides of the tunnel.
