The room and pillar system is used in mining coal, iron and copper ores mainly when found as manto or blanket sediments, stone and aggregates, talc, soda ash and potash. The key to the winning room and pillar mining is opting the optimum pillar size. If the pillars are so small the mine will fall down.
The Room amp; Pillar mining method is predominantly used in the US, South Africa and India. Global Mining offers the complete range of equipment for. The paper has described the most important machines in some detail, such as the Cat#174; Continuous Miners, Roof Bolters, Face Haulage Systems, Utility Vehicles and Feeder Breakers.
Room and pillar (variant of breast stoping), is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, quot;roomsquot; of ore are dug out while quot;pillarsquot; of untouched material are left to support the roof the size, shape, and position of pillars is a complicated procedure, and is an area of
The first full fleet of Cat branded roomandpillar coal mining equipment is being installed by Armstrong Coal in conjunction with the opening of its new underground mine at Creek in Kentucky. The mining company, a subsidiary of Armstrong Energy, purchased 24 machines from Cat dealer Whayne Supply following the dealerships acquisition of the former Bucyrus distribution and product
Continuous miners, used primarily in room and pillar mining and also to prepare roadways in a longwall systems, have incrementally improved over the last 20 years (Fig. ).But they are not advancing in automation as quickly as longwall equipment, with the exception that they are more often remotely controlled by an operator, rather than by an operator sitting on the machine.

In this system a series of parallel drifts are driven, with connections made between these drifts at regular intervals. When the distance between connecting drifts is the same as that between the parallel drifts, then a
Room and pillar is an underground mining method that has applications to a wide variety of hardrock deposits worldwide. It is commonly classified as an openstoping method, meaning that development involves mining out underground cavities while leaving the
RoomandPillar Underground Mining. ..330 52. capacity of a dragline, the machine used to remove the overburden in strip mining, varies in size from 10 to over 200 cubic yards. Many Eastern mines use stripping shovels instead of draglines; and stripping shovels currently
The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
