Ø The goal of the planning and design of underground coal mining operations is a strategy for designing an integrated mineral exploitation system that will ensure that coal is extracted and prepared at a desired market specification, at a minimum unit cost, within acknowledged safety, health, social, legal and regulatory constraints. Ø
Coal in the ground is classified as a coal resource and only once an applicable study has been completed to determine economic viability and based on a mine plan, can the coal be classified as a coal reserve. South Africa''s coal resources are contained in the Ecca deposits, a .
Recoverable reserves at producing mines are the amount of recoverable reserves that coal mining companies report to EIA for their coal mines that produced more than 25,000 short tons of coal in a year. EIA estimates these reserves at about 15 billion short tons of recoverable reserves, of which 62% is surface mineable coal.

Future coal mine expansions are highly uncertain as these expansions will face very serious geologic, economic, legal and transportation constraints. Importantly, the federal government owns essentially all of the coal in the western UnitedStates, and future coal mine expansions in western states will have to comply with a host of federal laws.

Most of the basin''s open cut and underground coal mines are located in the north. The basin had 48 operational coal mines in August 2011. In mid2011, evidence of a continuing mining boom was provided by state government figures which showed more than 50 mining projects are under consideration in the Bowen Basin.
Abstract. Groundwater impacts are a common reason for opposition to longwall mining. Most impacts are due to subsidencerelated fracturing. Although upper aquifers are protected from drainage to the mine by a confining zone, water levels decline due to fracture dilation, and drawdown expands outward a few hundred meters.
The coal industry in the United States—encompassing coal mining, processing, and transportation—is a relatively small but vitally important component of the nation''s provides nearly a quarter of all energy supplies in the United States, with most of this coal used to generate more than half of the nation''s electricity.
to expand coal exports at prices which can compete on the world market. If left unremedied, these constraints could severely damage the industry''s ability to achieve that goal. First, the cost of coal mining is increased by current health, safety and environmental regulations which often impose exces
Theory of Constraints in Mining Arrie van Niekerk, Business Consultant, South Africa, Member Hi, I have done over 50 implementations in mines. It covered all the major mining methods and minerals including gold, platinum, iron ore, manganese, coal, copper, chromium, nickel and we have seen some very good results.
