The two main types of mining are surface mining and underground mining. Mining is further divided into several other categories including room and pillar mining, slope mining, block caving, quarrying, openpit mining and in situ mining.

Mostly coal, but also gold, trona, and potash mining Block Caving Block caving is a technique in which the weight of the overlying rock is itself used to fracture an ore .

In particular, coal mines and other gassy mines are required to use equipment in certain areas of the mine that has been approved by the Mine Safety and Health Administration (MSHA) for use in a methane and coal dust environment to limit the risk of the equipment creating an ignitioncapable spark or a thermal energy ignition.

Surface mining, method of extracting minerals near the surface of the Earth. The three most common types of surface mining are openpit mining, strip mining, and quarrying. mining and coal mining. It has been estimated that more than twothirds of the world's yearly mineral production is .

The layout of Longwall could be either "advancing" type or of "retreat" type. In the advancing type, the gate roads are formed as the coal face advances. In thinner seams the advancing longwall mining method may be used. In the retreat type, the panel is a face connecting them both. Only the maingate road is formed in advance of the face.

The picks broke the coal loose from the veins. A hammer and wedge was used to reduce the size of a large block of coal so that it could be loaded into the coal cars by hand. The two copper disks are tags issued to the miners and are numbered. When a miner .

Fleet management systems help coal miners answer these questions more quickly and efficiently. They enable the scheduling and assignment of all types of equipment—haul trucks, loaders, drills, draglines, light vehicles, fuel trucks, support machines and more—from a central office location.

The two equipment types offering the greatest energy savings potential in the mining industry are grinding and diesel (materials handling) equipment (Exhibit 3). Implementing best practices and new advances through RD can save 356 TBtu/yr in grinding and 111 TBtu/yr in materials handling.
