Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 180 ft (55 m), are usually surface .
Mine Planning and Design Many of Tetra Tech's senior mining engineers have held senior positions in engineering and operations at the world's largest mines, where they gained insight into the realities of what makes active producing mines successful.
Subsequent chapters describe methane control methods for different kinds of mines and mining equipment, primarily for U.S. coal mines. These coal mine chapters include continuous miners and longwalls, including bleeders. Coal seam degasification is covered extensively. Other coal

MSHA and the mining industry have worked together to develop potentially life-saving technology that can stop machine motion and/or send a warning signal to the machine operator when it detects a person or object in the machine's path. Mine operators are increasingly installing these proximity detection systems on mining equipment in surface and underground mines to prevent

double-pass miners use the most advanced cutting technology for the continuous mining of coal and soft materials. Continuous miners cut and gather the material simultaneously and convey it into shuttle cars, haul trucks or a continuous haulage system. They are typically used for full-scale production in room-and-pillar mining operations.
quality of the seams, as well as the geology and environmental factors. Surface (opencast) mining and deep underground mining are the two basic methods of mining used in South Africa. Approximately 51% of South African coal mining is done underground and about 49% is produced by open-cast techniques.
Mine:an excavation made in the earth to extract minerals Mining:the activity,occupation,and industry concerned with the extraction of minerals Mining engineering: the practice of applying engineering principles to the development,planning,operation,closure,and reclamation of mines Some terms distinguish various types of mined minerals.
Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.
