TBM TREATMENT FOR CANADIAN COAL

CASE STUDY 1985: Exploitation of new reserves is key to a prosperous mining operation. Towards this end, mine operators are looking more to the tunnelling industry for rapid and economic methods of excavating access roadways and shafts for new projects. In the mid-1980s, a full face TBM was used for the first time by the mining industry in Canada to develop a vast coal deposit extending out under the Atlantic Ocean off Cape Breton Island, Nova Scotia.
