The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine's life." To expose and mine the ore, it is generally necessary to excavate and relocate large quantities of waste rock.
There are two main methods used in coal extraction: surface mining (above the ground) and subsurface mining (below the ground). Location is the biggest factor in determining what method will be used. Normally surface mining occurs west of the Mississippi river and subsurface occurs to the east.

What is Mine Reclamation? Reclamation is the combined process by which adverse environmental effects of surface mining are minimized and mined lands are returned to a beneficial end use. End uses may be open space, wildlife habitat, agriculture, or residential and commercial development.

Mine drainage refers to any surface water or groundwater that drains from an active or abandoned mining operation. Mine drainage can be high-quality similar to natural waters or contaminated by leftover materials. Polluted mine drainage can be extremely acidic and is often laden with high concentrations of toxic, heavy metals.
Drilling Machine Definition: Drilling is a material-removing or cutting process in which the tool uses a drill bit to cut a hole of circular cross-section in solid materials. This is the most common machining process, one estimate is that 75% of all metal cutting material removed comes from the drilling operation.
surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are too great to commence a surface operation. Once the economic feasibility has been verified, the most appropriate mining methods must be selected according to the
Requirements and Responsibilities. Mine Manager is responsible for the overall management of mining projects. Assists in staffing, outlining project plans, setting project goals/deadlines, and evaluating performance. Being a Mine Manager ensures the safety and health of mine workers. Recommends corrective action when problems are detected.
According to International Mine Action Standards (IMAS) 5, a (land)mine is a 'munition designed to be placed under, on or near the ground or other surface area and to be exploded by the presence, proximity or contact of a person or a vehicle'6. Mines can be either designed as 'anti -personnel' or 'anti …
Surface mining is a generic term describing several methods of mining mineral deposits from the surface, which entails removing the vegetation, top soil, and rock (called overburden materials) above the mineral deposit, removing the deposit, and reclaiming the affected land for postmining land use.
In addition to mining and processing equipment, surface mines typically have buildings and structures that provide space for offices, storage, maintenance and equipment refuelling. Before performing work at a mine, be sure to become familiar with the type, function and the location of equipment that you'll be exposed to in your work environment.
Stationary equipment at a surface mine typically performs hauling, processing, and other service functions. Structures provide offices, storage, and maintenance spaces. The following stationary equipment and structures are common to most surface mining operations: Conveyor systems. Feeders, bins, and hoppers. Crushers and screens.
Jun 07, 2019· The Mine Warfare Training Center (MWTC) is located at Naval Base Point Loma, Surface & Mine Warfighting Development Center Complex, San Diego, California. The Mine Warfare Training Center is home to the Mineman (MN) "A," "C," and "F" schools. MWTC functions as the premier instructional War Fighting Center of Excellence for Mine Warfare.
the Bureau of Mines undertook a project to produce a design manual that would ultimately guide surface mine road planners toward safer, more efficient haulage systems. Such a manual did not exist prior to the conclusion of this project. This manual was produced under a contract let by the Bureau of Mines to Skelly and Loy Engineers and Consultants.

Purpose. An inventory of land and water impacted by past mining (primarily coal mining) is maintained by OSMRE to provide information needed to implement the Surface Mining Control and Reclamation Act of 1977 (SMCRA). The inventory contains information on the location, type, and extent of AML impacts, as well as, information on the cost associated with the reclamation of those problems.
