The majority of coal is derived from opencast mines (#177;53%) and underground bordandpillar operations (40%), while stoping (4%) and longwall mining (3%) make up the balance. the importance of coal mining in south Africa Coal is South Africas most plentiful and cheapest source of energy.
The object of coal exploration is to determine the nature, location and extent of coal resources in a particular situation, such as a coal mining lease or a coalbearing sedimentary basin, and to identify the geological factors that may affect its economic, safe and environmentallyacceptable mining and use.

Coal Exploration and Mining Geology
2 #0183;#32;Except for the Chinese, who may have mined coal underground, all the early coal seams were worked from the surface, in fully exposed outcroppings. In the later Middle Ages, however, exhaustion of outcrop coal in many places forced a change from surface to underground, or shaft, mining.
The history of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity.
Exploration and Mining in British Columbia Numerous land use and zoning designations exist in British Columbia. To clarify the management of mineral sector activities, the province has confirmed in legislation a twozone system for mineral exploration and mining. The twozone system ensures mining applications are considered, subject to all
A program of geological exploration for coal usually has one of two possible objectives: (a) to find an area from which a given amount of coal of a specific quality may be successfully recovered, or (b) to determine the amount and quality of coal that can be economically extracted from a given area.
Coal exploration includes activities and evaluations necessary to gather data for making decisions on such issues as the desirability of further exploration, the technical feasibility of mining (including favourable and unfavourable factors), and economic feasibility (including size of mine, coal quality assessment, marketability, and preparation of mined coal for market requirements).

Coal bed methane production is becoming more common, whether primarily for gas production or to remove gas prior to mining. If these holes can be used for exploration without compromising their use for gas drainage then savings can be obtained.

#0183;#32;Tin and coal have gone through the exploration stage, and exploitation has been ongoing for many years, therefore, the effect of their exploration and exploitation is quite apparent. It is hoped that the observed impacts on the environment from the exploitation of tin and coal will be useful antecedents in putting together a comprehensive environmental management standard for the mining
