The first published, reference to the mining of coal in India dates back to the year 1774 in the Raniganj Coal Field. Coal mining methods can be broadly divided into two types viz. Surface Mining Methods and Underground Mining Method. The Indian coal industry is the world’s third largest in terms of production and fourth largest in terms of ...
Surface Mining Methods and Equipment
expensive surface mining method. Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside.
Mining - Wikipedia
The Push-beam system can penetrate nearly 1,000 feet (300 m) into the coal seam. One patented high wall mining system uses augers enclosed inside the Push-beam that prevent the mined coal from being contaminated by rock debris during the conveyance process.
Coal - Wikipedia
Power stations that burn coal also consume large quantities of water. This can affect the flows of rivers, and has consequential impacts on other land uses. In areas of water scarcity, such as the Thar Desert in Pakistan, coal mining and coal power plants would use significant quantities of water.

Classification of Coal Resources Using Drill Hole Spacing ...
international classification standards has required a geostatistical analysis for the estimation and classification of coal resources. The purpose of this research is to apply geostatistics method to determine optimal drill hole distance, and to analyze classification of coal resource based on data of coal quality and quantity.
Mineral profile - British Geological Survey
cent of available coal in an underground mine is recovered. Waste rock in the mined coal is disposed of on an adjacent tip. In many parts of the world, waste tips are now land-scaped and vegetated to reduce environmental impact. The room and pillar (also called pillar and stall) mining method is used generally at shallow depths, where it is
Appendix F: Underground Coal Mining Methods …
16-5-2018 · Underground Coal Mining Methods and Engineering Dust Controls. An underground mine consists of the portals (entrance and exits to the mines), mains, submains, panels, and working faces. The panels are the working sections of the production operation. Depending on the mining method, a working section can have one or more working faces.

A Study of Rockburst Hazard Evaluation Method in …
15-12-2015 · With the increasing of coal mining depth, the mining conditions are deteriorating, and dynamic hazard is becoming more likely to happen. This stone analyzes the relations and differences between rockburst in the coal mine and rockburst in the metal mine. It divides coal mine rockburst into two types including static loading type ...
(PDF) Mining Methods: Part I-Surface mining
Through the use of a range of geochemical techniques, this work quantitatively and qualitatively investigated the effect of open-pit coal mining operations on rice paddy soils and rice plants grown for local consumption in the city of Cam Pha in the Quang Ninh province of North-Eastern Vietnam.
Geotechnical roof classification for an underground coal ...
Several rock mass classification systems have been developed and used in civil engineering design and for underground mining operations. In the past, these rock mass classification systems were modified and used in the coal mining industry to quantify descriptive geological information for use in coal mine design and roof support selection.
Mineral processing - Wikipedia
A number of auxiliary materials handling operations are also considered a branch of mineral processing such as storage (as in bin design), conveying, sampling, weighing, slurry transport, and pneumatic transport. The efficiency and efficacy of many processing techniques are influenced by upstream activities such as mining method and blending.
Underground mining method selection by decision …
Underground mining method selection is one of the most important decisions that mining engineers have to make. Choosing a suitable underground mining method to extract a mineral deposit is very important in terms of economics, safety and productivity of mining operations.
