Because of Uieir demonstrated capabilities in attaining high rates of advance in civil tunnel construction, the hard rock mining industry has always shown a major interest in the use of TBMs for mine development, primarily for development of entries, as well as ventilation, haulage and production drifts. The successful application of TBM …
An alternative to traditional drilling and blasting methods, tunnel boring machines are used mainly with longer tunnels because of upfront costs. Typically, trenchless construction, or horizontal directional drilling, are used to dig shorter tunnels. Other mining machines for drilling through hard rock, soil, and sand are also available.

From there the material can be transported out of the tunnel without problems. After each jacking stroke, the drilling process is stopped for a short time, to secure the pipe string and the drilling unit. Then the next jacking pipe can be installed in the jacking frame. When the desired drilling length is reached, the drilling unit is retracted.
The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Robbins' close partnership with the mining industry spans decades, from non-circular prototype machines such as the Mobile Miner to early TBM usage in coal, copper, and gold mines worldwide. While those early machines were successful, modern machines are vastly more powerful and efficient than those tested and used in the 1970s and 1980s.
Our high-tech machines enable high advance rates in any geology with maximum safety for buildings, infrastructures and personnel. Working in teamwork together, modern, integrated tunnel systems for metro, road, railway, passenger, supply and disposal tunnels are the result – built on budget and on schedule.
