Coal Exploration and Mining
In the second part, two basic methods of extracting coal, i.e. surface mining and underground mining, are introduced. Firstly, two main methods—strip mining and open-pit mining—of surface mining are discussed. In underground mining, room and pillar, shortwall, and longwall mining methods …
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 (including size of mine, coal quality assessment…
Drilling Methods Used in Coal Mines | Geology for Investors
Jul 31, 2013 · 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 Techniques by Micheal Moroskat on Prezi

Coal Exploration and Mining Geology
2. Objectives of Coal Exploration Programs As indicated above, coal exploration is the first part of a continuous process, that if successful leads to the establishment of a new coal mine or the extension of an existing mine into a previously unexplored area. The object of coal exploration is to determine

Coal mining - Choosing a mining method | Britannica
Surface coal mining generally involves the following sequence of unit operations: (1) clearing the land of trees and vegetation, (2) removing and storing the top layers of the unconsolidated soil (topsoil), (3) drilling the hard strata over the coal seam, (4) fragmenting or blasting the hard strata with explosives, (5) removing the blasted material, exposing the coal seam, and cleaning the top of the coal seam, (6) …
Exploration | Introduction | underground COAL
EXPLORATION. Before any preparation for mining operations commence, it is necessary to know at least something of the resource to be exploited to be sure it will be an economic exercise. The gaining of information for this purpose is a process known as exploration.
Appendix E: Coal Mining and Processing Methods | Coal ...
Even in mines where the longwall method is the principal extraction method, the development of the mine and the longwall panels is accomplished by room-and-pillar continuous mining. The thickness of the coal seam, the depth and inclination of the coal seam, the nature of roof and floor strata,...
Handbook for Mineral and Coal Exploration
Mineral and coal exploration involves activities intended to locate, identify and inventory these resources, to develop mines and contribute to BC‘s sustainable economy. Through a variety of sampling techniques, explorationists work to describe and define their resource‘s extent and potential value.
3 Technologies in Exploration, Mining, and Processing ...
The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of ...
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 exploration modelling using geostatistics in Jharia ...
Jun 01, 2013 · However, no exploration modelling work had been carried out using geostatistics. Owing to the presence of high quality coking coal in Jharia coalfield, it has been considered necessary to model and evaluate coal seam characteristics using geostatistics to provide improved means to coal …
Exploration geophysics - Wikipedia
Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties.
Exploration Methods Explained: Drilling
Most advanced exploration for coal and minerals uses a combination of diamond and reverse circulation drilling. RC drilling is similar to water bore drilling and the latest rigs are mounted on a 4WD vehicle

Seismic Coal Exploration | ScienceDirect
Thus, to reduce mining costs it is essential to delineate the geology prior to mining. Today, the only effective geophysical tool to detect and to map minor faults in front of the coal cutter is in-seam seismics using channel, or so called seam waves. The techniques are well established and successfully applied for more than two decades.
