Definition of continuous mining Mining in which the continuous mining machine cuts or rips coal from the face and loads it onto conveyors or into shuttle cars in a continuous operation. Thus, the drilling and shooting operations are eliminated, along with the necessity for working several headings in order to have available a heading in which loading can be in progress at all times.

The Continuous Mining Process Typically, to begin a room, the continuous miner engages in cutting (removal) a 3 m (9.8 ft) wide sec-hon of coal to a depth determined to be safe based on local geologic conditions and mining regula­ tions-on average up to 6.1 m. Deeper cuts can be made (called extended-cut mining) with special per­

C ontinuous mining systems have been established in coal and soft rock mining for about a century now and the technology to cut through hard rock has been successfully used in civil engineering projects since the late 1950s. One would think that by now, continuous hard rock mining would also be a reality but it is not. The possibility of the technology being applied to hard rock mining has in ...

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, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof overburden.Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of ...

The 12CM12 continuous miner, with a solid-head cutting head system, features a 965 mm (38 in.) conveyor width for standard width entry applications. The 12CM12, as well as all 12CM series continuous miners, are designed specifically to make efficient use of the additional space available in higher seam heights by offering improved outboard access to all major components.

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.
