Electrically powered, track-mounted continuous miners from TON are designed to cut coal and soft minerals in a continuous process, eliminating the need for drilling and blasting. TON design engineers focus on health and safety as well as total cost of ownership to create highly productive and reliable continuous mining solutions.

Continuous miners Introduction underground COAL

The term "continuous" as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading.
