equipments in a coal mining process


Posted on November 18, 2018



Coal Mining Technologies - TEEICCoal is mined using giant machines to remove the coal from the ground. There are two basic methods to remove coal: surface mining and underground mining. Surface mining is used when the coal is typically less than 200 feet below the surface. Giant machines are used to remove the top layers of soil and rock to expose.equipments in a coal mining process,Modern Mining Equipment - Kentucky Coal EducationDevices related to the transportation of coal from the mine to processing facilities to rail loading and finally to the consumer: conveyors, underground and overland · barge · ship · railroad · trucks.
