longwall mining is more efficient than room and pillar mining, but the equipment is more expensive. surface mining for extracting coal which lies close the surface, huge drag-line shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines.the oldest of the basic underground methods, room-and-pillar mining grew naturally out of the need to recover more coal as mining operations became deeper and more expensive. during the late conventional techniques began to be replaced by single machines, known as continuous miners, that broke off the coal from the seam and transferred mar 27, 2019 coal preparation plant process and equipment for coal washing. published date: 019. the necessity of coal preparation. various mineral impurities are mixed in the raw coal mining process. the quality of raw coal is affected by technical equipment and geological conditions.To remove coal in these underground mines, miners ride elevators down deep mine shafts where they run machines that dig out the coal. processing the coal. after coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. the plant cleans and processes coal to remove dirt, rock
method, a continuous mining machine excavates the coal and loads it onto a conveyor or shuttle car in a single step. despite the term continuous, the machine operates only part of the working time, because after mining advances about feet, the machine is withdrawn from the face so that roof bolts can be installed tolongwall mining mining. a mining method in which very long rectangular blocks of coal are defined during the development stage of the mine and then extracted in a single continuous operation by an automated cutting head moving parallel to the coal face.when the coal is cut, the working area is protected by a movable, powered roof support system. As the face progresses, the immediate roof
