Patent

CA 2060288

A non-explosive mining apparatus has a series of modules each having a base capable of movement over a footwall in a mine working and each carrying a portion of a rail. The modules are locatable side-by-side with one another with the rail portions in alignment so as to form a continuous rail extending generally parallel to the working face in the mine working. At least one carriage is provided which can be driven along the rail. The carriage carries a circular saw that can be driven in rotation to form a cut in the working face as the carriage moves along the rail. The carriage is designed for the saw to be able to perform tilting and stewing movements.
