About Surface Mining. • Surface mining is an operation that involves the recovery of shallow coal deposits from the ground through the removal of overlying rock by excavators and dump trucks. • The first part of the process is to remove the soils. The top soil and sub soil is .
excavation could provide the desired coal quality at 52% lower costs when the whole process (excavation, transportation, processing, etc.) was considered. Keywords: coal mining, surface mining, selective mining. * Dumlupinar University, Department of Mining Engineering, Kütahya, Turkey. † Eylül University, Department of Mining Engineering,
Strip mining is the process of scaping the coal from the top surface of the ground. The problem with peat is that it has a very low heat value per kilogram of the fuel burned. In addition, strip mining is ecologically very destructive unless the mining company makes a conscious effort to restore the country side.

Surface mining can cause mudslides, landslides, and flashfloods which is a threat to human life and property. Moreover, depending on the chemical makeup of the coal deposit, mines can pollute local drinking water sources with toxic chemicals like selenium, arsenic, .
Under the provisions of the Federal Surface Mining Control and Reclamation Act of 1977, 9587, the Department of Interior, Office of Surface Mining Reclamation and Enforcement, has implemented a federal program for coal mining in Michigan.

In the 1930, surface mining represented about 8% of the coal mining process (90% of coal mining was done underground). In the late 1970s, surface mining represented almost 60% of the entire mining process (Joyce, 1998).
INTRODUCTION TO MINING ... that can be utilized as fuels,such as coal,petroleum,natural gas,coalbed methane,gilsonite,and tar sands. It should be noted that the mining engineer is associated with the extraction ... entirely open or operated from the surface,it is termed asurfacemine.
MINING PROCESS. After the coal mining permit is issued the first thing the mining company does is mark the permit boundaries and put up a mine identification sign. Then the company builds sediment ponds and berms. This is done to control all surface drainage, so that none leases the permit area without first passing through a sedimentation pond.
This area includes all areas which are or will be affected by the surface coal mining activities during the term of the permit. Precipitation event—A quantity of water resulting from drizzle, rain, snow, sleet or hail in a limited period of time. It may be expressed in terms of recur rence interval.
at surface coal mines, dust is produced by removing, loading, hauling and dumping soil and overburden. Dust is also produced when ore is basted apart. Noise is created by equipment and blasting. Most surface mines are not located near urban populations. Regulations in US forbid mining operations to allow dust or noise to exit the area being mined.
Feb 19, 2013· There are two types of mining: underground mining and surface mining. When the coal seam is fewer than 125 feet under the surface, it is mined by surface mining.
