Dec 27, 2018· Each segment requires the use of specific equipment, but there are several types of mining equipment that are used throughout the industry. This equipment includes excavators, draglines, drills, roof bolters, continuous miners, longwall miners, rock dusters, shuttle cars and scoops.

double-pass miners use the most advanced cutting technology for the continuous mining of coal and soft materials. Continuous miners cut and gather the material simultaneously and convey it into shuttle cars, haul trucks or a continuous haulage system. They are typically used for full-scale production in room-and-pillar mining operations.

A dragline excavator is a piece of heavy equipment used in civil engineering and Surface mining. Draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built on-site. Most crawler cranes, with an added winch drum on the front, can act as a dragline.
