    MNGN INTRODUCTORY MINING. Semester Hrs. INTRODUCTORY MINING (I, II) Survey of mining and mining economics. Topics include mining law, exploration and sampling, reserve estimation, project evaluation, basic unit operations including drilling, blasting, loading and hauling, support, shaft sinking and an introduction to surface and underground mining methods. A recent American study reviews the problems solved and those unsolved in underground coal gasification [19]. The survey points out that a satisfactory solution has not yet been found for two problems of exceptional importance which form the principal obstacles to the commercial development of the method: problems connected with ground. In the previous topic we learned that the economics of mining is particularly related to the amount of ore that can be produced and the amount of waste rock that must be moved. That makes underground mining particularly suited to structurally compact ore bodies with high grade ores which don’t require an extensive network of access tunnels through worthless rock and which .

[Washington]: Bureau of Mines, [] (OCoLC) Online version: McCulloch, C.M. (Charles M.). Geologic investigations of underground coal mining. A series of geological surveys were completed in six coal mines in connection with a Bureau of Mines research program on methane control.

The aim of these surveys was two fold: first, to study the overall geology of the coalbed, and second, to use the resulting data to evaluate the influence of the geological characteristics of the coalbed on safe and efficient coal extraction.

GEOLOGIC INVESTIGATIONS OF UNDERGROUND COAL MINING PROBLEMS by C. McCul loch, 1 P. Jeran, 1 and C. Sul l ivan2 ABSTRACT A series of geological surveys were Geologic investigations of underground coal mining problems book in six coal mines in connection with a Bureau of Mines research program on methane by: 6.

This report explains the advantages of geologic maps and fence diagrams in coal mining and how the knowledge gained from such geologic investigations of mines can help control many underground problems.

Additional Physical Format: McCulloch, C.M. (Charles M.). Geologic investigations of underground coal mining problems ii, 30 p. (OCoLC) Material Type.

This paper covers geologic exploratory methods, data organization, and the value of collecting and interpreting geologic information in coal mines to enhance safety and production. The implementation of the methods described above has been proven effective in predicting and mitigating adverse geologic conditions in underground coal : Mark Van Dyke, Ted Klemetti, Joe Wickline.

Underground coal mining is the extraction of coal from below the surface of the earth. The coal is worked through tunnels, passages, and openings that are connected to the surface for the purpose of the removal of the coal.

Fatalities and injuries are a prominent concern, but lost time due to cleanup and disruption of mining. "Major problems facing the development of coal and gas resources of the Hartshorne Coalbeds include the complex distribution of minable and unminable coal, high methane content and bed pressure, faulting, variations in degree of dip, presence of natural gas fields in associated sandstones, and legal problems, caused by local geologic characteristics, in identifying gas Cited by: 3.

The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for —the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2.

Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig.

Miners face numerous problems in the process of underground coal extraction such as high temperature, humidity, coal and silica dusts, harmful gases, the rock stresses, and the disturbance due to.

Mining investigations. GeoCon have a vast experience in designing and undertaking mining investigations. Coal mining has been an influencing part of history and industry over the last years and the impact that it has left is also quite extensive.

In general, wherever the roof rock type in a mine changes abruptly, the presence of adverse geologic structure and chang- ing roof bolt anchorage characteristics should be suspected. Coal Rolls In western underground coal mines, a coal roll, as defined by Bunnell (25), is "an undulation in the coal seam.".

The influence of discontinuities on coal measures is manifested in the form of roof and side falls, caving of the roof and sometimes in subsidence of the ground surface.

This review paper is confined to roof falls due to major geological discontinuities (such as faults, joints, cleats and bedding planes) and to possible ways and means to prevent these falls.

Mining. Coal is mined by both surface or ‘opencut’ (or opencast) and underground or ‘deep’ mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia’s coal is produced from opencut mines.

A year ago April, America suffered its worst mining disaster in 40 years with the explosion at Massey Energy’s Upper Big Branch mine in West Virginia on April 5, that resulted in the death of 29 coal miners.

As part of its mission, GSA explores and evaluates the mineral, water, energy, biological, and other natural resources of the State of Alabama and conducts basic and applied research in these fields.

The environmental toll of underground mining is significant. It includes air pollution, changes in water-flow patterns, chemical and gas seepage into water supplies and soil, inaccessible fires in abandoned mines, and dramatic changes in land composition that can make the area unusable after the mining operation is done [source: Saxena].

Broader terms: Coal mines and mining; Energy industries -- Environmental aspects; Mi. Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the s, has been widely used to generate electricity.

Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a pit. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy.

It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of coal deposits.

Falls of roof continue to be a major hazard in underground coal mining. This study exami reportable noninjury roof falls that occurred from to in room-and-pillar operations in the bituminous coal sector.

An average of 1, falls were reported per year during the study period. Key findings include the following:Cited by: 2. The International Journal of Coal Geology deals with fundamental and applied aspects of the geology and petrology of coal, oil/gas source rocks and shale gas resources.

The journal aims to advance the exploration, exploitation and utilization of these resources, and to stimulate environmental awareness. Coal Geology, second edition, offers a thoroughly revised and updated edition of this popular book which provides a comprehensive overview of the field of coal geology.

Coal Geology covers all aspects of coal geology in one volume, bridging the gap between the academic aspects and the practical role of geology in the coal industry. The object of the book is to provide the reader 4/5(1).

Drilling boreholes into the coal seam (possibly also in adjacent seams) prior to mining and connecting these to a pipe range to remove any gas to a place where it can be dealt with, most commonly the surface.

Usually a vacuum is applied to the pipe range to enhance gas capture. This process is known as "pre-drainage".

Mining is never properly done in isolation,nor is it an entity in itself. It is preceded by geologic investigations that locate the deposit and economic analyses that prove it financially feasible. Following extraction of the fuel. Longwall mines produce more than 30 pct of all underground coal, up from 5 pct just 15 years ago.

The continued growth of longwall mining without appropriate multiple-seam planning may increase the cost and risk of mining. Optimization of the mine design factors is arguably the primary means for controlling interactions between operations.
