Overview on the appliion of geophysics in coal mining ...
The range of appliions in both surface and underground mining is extensive. Appliions include coal seam mapping and geological fault detection, lithological mapping, geotechnical evaluation, assessment of the rock mass response to mining, detection of voids, loion of trapped miners and guidance of drills and mining equipment.

Geological and geotechnical aspects of underground coal ...
· About one quarter of the coal produced in Australia is by underground mining methods. The most commonly used underground coal mining methods in Australia are longwall, and room and pillar. This paper provides a detailed review of the two methods, including their advantages and disadvantages, the major geotechnical and operational issues, and the factors that need to be .
Stratigraphic controls on water quality at coal mines in ...
Water quality at four coal mines in southern New Zealand can be related directly or indirectly to the geology and mineralogy of the stratigraphic sequence in which the coal mines occur. The Late Cretaceous Taratu Formation of the Kaitangata coalfield formed in a marginal marine setting during regional marine transgression, and marine incursions punctuated coal formation.
Coal Geology | Geoscience Australia
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.

Measure while drilling: a case study at Daunia Coal Mine
Reducing coal loss and dilution in our mines is a growing focus in mining efficiency and maximising resource value. Blast damage to coal roof is a significant cause of coal loss and dilution in mines across the world. Typically, when a Geologist is modelling a coal roof surface, touch coal records from production drillers are used to support existing exploration data.
Features Associated with Abandoned Coal Mines in Indiana ...
Indiana is currently the sixth largest coalproducing state in the United States, and it has a long history of coal mining. Largescale mining has been conducted by both underground and surface methods. Both of these methods necessarily involve the movement of large volumes of earth materials, including bedrock, unconsolidated surficial deposits, and soils.

The bedding planes are the most continuous of the geological structures in the strata and typically exhibit persistence on the order of hundreds of meters. In general the bedding at the mine dips to the west and southwest at inclinations of 10º to 30º. The aggregate thickness of the coal seams in the active mining area is about 60 m.

Wilpinjong Thermal Coal Mine
· A map of the Wilpinjong coal mining area. The Wilpinjong coal mine is loed in New South Wales, Australia, approximately 40km northeast of Mudgee and ten kilometres southeast of the Ulan mine. Spread over 2,800ha, the mine began operations in late 2006. It is owned by Peabody Energy, which acquired the property from Excel Coal in late 2006.
Masama Coal Project
Masama coal project loion and geology. The Masama coal mine occupies 120km² on the southwestern edge of the Mmambula coalfield, which is spread over 420km² and is divided into three blocks, namely the West, Central, and East blocks. Masama coal mine forms part of the West block of the Mmambula coalfield.
Origin and influence of coal mine drainage on streams of ...
Effects of coal mining on water quality in the more arid western half of the United States are more difficult to detect because of the high degree of mineralization of natural water. Normal background concentrations of constituents are not useful in evaluating effects of coal mine drainage on streams in the more arid West.

· Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create .
