Where the bed crops out at the surface, the coal has been mined out. You are considering the feasibility of mining it underground. You have acquired the necessary permits and permission to dig a vertical mine shaft 2 km away from the surface outcrop, and mine the coal (see figure). 1.
Surface Coal Mining The greater proportion of the worlds mineral needs are at present provided by surface mining methods, more or less 60% of the worlds mineral needs without including coal and lignite. When coal and lignite production is also included, the total amount rises to above 70%.

In 2017, renewable energy accounted for % of the total energy used for heating and cooling in the European Union. This paper analyses the technical and economic feasibility of using mine water from flooded underground coal mines in Spain to provide renewable thermal energy to buildings located in surrounding areas.
A Feasibility Analysis of Wind Power as an Alternative Postmining Land Use in Surface Coal Mines in West ia Alek Charles Duerksen Surface coal mining in West ia has supplied energy to the eastern coast of the United States for over a century. Over the years, the coal mining industry has been forced to adapt as
Beneath the surface. Subject to the outcome of the feasibility study and receipt of requisite approvals, we intend to construct a multiseam underground longwall metallurgical coal mine and processing plant with a dedicated rail spur and train loadout facility.
Feasibility studies are required throughout the preproduction stage of every mining project to justify continued investment in the subsequent phase. Usually a concept study or scoping study is followed by one or more prefeasibility studies that reflect the increasing level of technical and economic knowledge gained at the various earlier stages.
Although both methods have their benefits and drawbacks, underground drilling may just be the cost worthy selection for you Mining for coal depends on many variables. The geology and environmental aspects play a vital role, but depth and quality of the seam is what brings home the bacon. Depending on where the seam (profitable bed of coal) is located, extracting this black gold can require a ...
Apr 11, 2003· Coal mining can result in a number of adverse effects on the environment. Surface mining of coal completely eliminates existing vegetation, destroys the genetic soil profile, displaces or destroys wildlife and habitat, degrades air quality, alters current land uses, and to some extent permanently changes the general topography of the area mined.
Mining of coal begins once the mineable coal reserve is determined; depending on the chosen method, coal reserve is an input to the mine operations, and the output incudes coal which is stockpiled at the mine then supplied to the power station. For surface mines in particular, the other outputs include waste rock that deposited in waste dumps ...
The urgent need for the control of surface subsidence caused by longwall enal mining in densely populated areas of China has led to a feasibility study on the effectiveness of longwall goaf cemented hack fill. The study u focussed on exploring the potential of longwall goaf cemented backfill practice for surface subsidence control. Specific backfill...
At full production, the New Elk Coal Company mining complex is scheduled to produce over 3 million tons of metallurgical coal per year for 20 plus years from at least four coal seams. The mine will utilize some of the surface and underground infrastructure remaining from two closed underground coal mines that operated on the property.
In 2015, AAI completed two CSIRO HI Cell stress measurements and installed six CSIRO HI Cells for longterm monitoring for the National Institute for Occupational Safety and Health (NIOSH) on the 2 Panel ahead of the longwall retreat at the Leer Mine (underground coal).
The prefeasibility study defines an opencut strip mining operation utilising conventional truck and shovel equipment for overburden removal, Continuous Surface Miner for coal mining and waste backfilling to maximise inpit dumping thereby ensuring minimal environmental disturbance.
The research presented in this thesis investigates one potential solutionâ or component of a solutionâ to improve the sustainability of surface coal mining in West ia: postmining wind power. This thesis intends to demonstrate and explain the feasibility of synergistic mine closure and wind development.
CHAPTER 11 Mining Technology The Federal Coal Leasing Amendments Act of 1976 charged OTA to assess the feasibility of the use of deepmining technology on leased areas. With the passage of the Surface Mining Control and Reclamation Act of 1977 congressional interest in the study of deep underground mining technology shifted
Recommendation: There should be renewed support for advanced coal mining and processing research and development to optimize use of the nation’s coal resources by increasing the amount of coal that is economically minable through technological advances …
Mining engineering is an engineering discipline that applies science and technology to the extraction of minerals from the earth. Mining engineering is associated with many other disciplines, such as mineral processing, Exploration, Excavation, geology, and metallurgy, geotechnical engineering and mining engineer may manage any phase of mining operations – from exploration and ...
His experience includes engineering management at both surface and underground coal mining operations throughout the US, Canada, Colombia, South Africa and Australia, as well as mine planning and design, feasibility studies, due diligence investigations, operational analysis, and contract mining.

Administers the programs for controlling surface coal mining operations required by the Act.* Reviews and approves or disapproves State programs for controlling surface coal mining operations and reclaiming abandoned mined lands. Makes those investigations and inspections necessary to insure compliance with the Act.
Fernando Rodrigues is a mining engineer with 17 years of global mining experience. Fernando's recent work has involved project management and contributions to multiple feasibility and prefeasibility studies, preliminary assessments, due diligence and competent person reports pertaining to reserves, mine plan optimization and infrastructure.
(1) shaft mines, which are likely to have minimum surface expression, 8 (2) IIcoal slopell mining, which requires the use of an inclined opening to tap the coal seam, and (3) IIcoal slipll mining in which coal was taken from nearsurface areas having very little overlying material to be removed.
economic feasibility of the vertical transport (hydraulic hoisting) of coal by pipeline from underground mines, The scope of the study excludes horizontal pipeline transport within the mines, and from the mine surface to preparation plants, These possibilities are left to future consideration,
regulation of surface coal mining and reclamation within the United States. G. Section 503 of Public Law 9587** provides that each state may assume and retain exclusive jurisdiction over the regulation of surface coal mining and reclamation operations within such state by obtaining approval of a
This report is the result of information obtained from a review of related literature, personal inquiry, and onsite examination of active surface coal mining operations. Four improved surface coal mine systems are described in detail and evaluated for feasibility, implementation requirements, environmental benefits, and costs.
