Coal mining Prospecting and exploration Britannica
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
Coal Exploration and Mining
Ground or vehicle-borne magnetic surveys are more commonly used for closer investigations in coalfield exploration. They may be used to provide further information on basement controlled geological structures, or to map out any bodies of mafic igneous materials, such as sills, dykes, and lava flows that occur within the area.
STRATEGIC STATEMENT ON COAL EXPLORATION AND MINING IN
Royalties from coal brought in around $2 billion in 2018-19, used to fund public servic es and infrastructure. In NSW, around 80 per cent of our electricity currently comes from coal. Some 85 per cent of the coal mined in the state is exported, mainly to Japan, China, South Korea and Taiwan, where it is mostly used to generate electricity.

Drilling Methods Used in Coal Mines Geology for Investors
17/10/2019· The aim is to to confirm survey data about the location and extent of the coal deposits or seams. Additionally, exploration drilling is used to identify or confirm the location of faults, folds, dikes, sills, and other geologic features that may influence how the coal is ultimately mined.
Coal Exploration and Mining Geology
A variety of geological techniques is used in coal exploration is including field mapping, interpretation of air photos and satellite images, and airborne and ground geophysical surveys such as gravity, magnetic and seismic studies.
Coal Geology Geoscience Australia
Coal reserves are discovered through exploration. Modern coal exploration typically involves extensive use of geophysical surveys, including 3D seismic surveys aimed at providing detailed information on the structures with the potential to affect longwall operations, and drilling to determine coal quality and thickness. Mining. Coal is mined by both surface or ‘opencut’ (or opencast) and
Exploration Introduction underground COAL
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. There is a tendency in recent times to run mine services (air, water, power cables, etc) in boreholes rather than in drifts or shafts exploration

Types and models of coal-deposit exploration in China
information that can be used to keep coal exploration efficient and safe. China’s coal resources are plentiful and distributed widely, with various coals providing a good foundation for clean utilization of coal resources (Han et al., 1980; Mao et al., 1999; Sun et al., 2002). However, the situation becomes gloomy when one takes into account the uneven distribution of coal in quantity and
