Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically – m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (– mi) long and 250–400 m (820–1,310 ft) wide.
Equipment. NOTE: although the following sections deal with individual items of equipment in isolation it is noted a longwall face comprises a number of components that have to be fully integrated and work as a complete unit they cannot be designed and installed in isolation from each other and be expected to operate successfully.

Is deep drilling worth the cost? While underground mining requires an array of resources, equipment and financial backing, the method is best suited if the environment and coal potential harmonize. Longwall mining accounts for 50 percent of coal mines in the world and is much safer than other methods of coal mining.
underground loaders and trucks are engineered for safety, productivity and reliability in even the toughest applications. Rugged, compact and highly maneuverable, these equipment offer impressive capacity for their size, and a low cost per tonne.

The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today.
LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the .
No two underground operations are the same—what, how and where you mine are unique. So we don''t offer onesizefitsall solutions. Our underground mining equipment are designed specifically for hard rock or soft rock applications, as well as for longwall, highwall, or room and pillar operations.
