The 4200 SM surface miner was integrated into an ongoing operation for the selective mining of coal and interburden. Previously defined targets were checked regularly to determine if they were being met. The project score card (Fig. 3) illustrates the advantages of using a surface miner in this mine.
In general, most contemporary surface mining operations rely on mobile drill rigs, hydraulic shovels, front-end loaders, scrapers and haul trucks to extract ore and initiate ore processing. The larger the mine operation, the larger the capacity of equipment required to maintain the mine plan.
production method to become an integral part of many surface mining operations throughout the U.S. and the world. Auger mining in the Appalachians began sometime in the mid 1940s when surface miners turned vertical blast hole drills horizontal at the economic limit of a surface pit to recover more coal from the highwall.

This article applies to any person conducting surface coal mining operations; and to all surface coal mining operations conducted after August 1, 1980, on lands from which the coal had not yet been removed and to any other lands subject to North Dakota Century Code chapter 38-14.1 or this article. 1. This article does not apply to: a.
Aug 18, 2015· Mining operations are complex. They aren't your run-of-the-mill type projects. These billion dollar complexes consist of various interconnected projects, operating simultaneously to deliver refined commodities like gold, silver, coal and iron ore. It's a five stage process and we've broken it down using GIFs. Exploration
Mountaintop removal mining (MTR) is a form of surface mining increasingly being used to replace underground mining to extract coal from the Appalachian Mountain regions of eastern Kentucky, southwest West a, southwest ia and eastern Tennessee. The process involves using explosives to remove up to 1,000 vertical feet of rock to reach ...

results. Generally, a near-surface coal deposit is mined using surface mining methods, and a deep deposit by underground methods. Mining of coal begins once the mineable coal reserve is determined; depending on the chosen method, coal reserve is an input to the mine operations, and the output incudes coal which is stockpiled at the mine then ...
Apr 11, 2003· Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine - a pit, and the ...

or shell dredging operations. Other mines included are: surface marble, granite, sandstone, slate, shale, trap-rock, kaolin, cement, feldspar, or lime operations. Part 48 applies to all underground mines and all other surface mines that are not included in Part 46. Q: We have surface operations at our underground coal mine.
For example, in coal and other soft rock mines, continuous miners break and load the mineral to eliminate drilling and blasting; boring machines perform the same tasks in medium-hard rock. The cycle of operations in surface and underground mining differs primarily by the scale of the equipment.
According to 30 USCS § 1291 (28), the term surface coal mining operations means--"(A) activities conducted on the surface of lands in connection with a surface coal mine or subject to the requirements of section 516 [30 USCS § 1266] surface operations and surface impacts incident to an underground coal mine, the products of which enter commerce or the operations of which directly or ...
"surface mining" more broadly so that exemption applies to machinery and equipment used in (1) strip mining, open pit mining, and contour mining operations, (2) quarrying, (3) the mining of surface deposits that lie exposed in their natural state, (4) reclamation projects undertaken by
Mining Operation: Types, Impacts and Remedial Measures! Mining is the process of taking mineral and other substances from the earth. These substances include metal compounds, non-minerals such as coal, sand, oil and natural gas and many other useful things.
Once coal removal is complete, final regrading takes place and the area is revegetated. The operation is required to reclaim the mine to "AOC" or "approximate original contours" unless this requirement has been waived by the agency that has granted the Surface Mining Control and Reclamation Act of 1977 (SMCRA) permit for the operation.

face mining techniques. Surface mining operations are usually well-suited to the many areas of the West that have not yet ex-perienced the extensive development of towns, cities, highways, and railroads char-acteristic of the Midwest and the East. Surface Mining Techniques Surface mining of coal .
"Strip mining" is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden).It is most commonly used to mine coal and lignite (brown coal).Strip mining is only practical when the ore body to be excavated is relatively near the surface.
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining has finished.
