Coal mining - Choosing a mining method | Britannica

20-7-2020· Coal mining - Coal mining - Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many …

Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, 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', and ...

Coal - Structure and properties of coal | Britannica

Coal - Coal - Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and hydroaromatic ...

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Guidance note for coal mines to develop and implement a management structure This guidance note has been issued by the Mines Inspectorate from the Department of Natural Resources and Mines (DNRM) to provide guidance to coal mines in developing and implementing a management structure.

Small mine size is associated with lung function ...

Inhalation of coal mine dust causes coal workers’ pneumoconiosis (CWP) and other diseases affecting lung function. The prevalence of CWP among US coal miners has doubled since the late 1990s. Previously, small mine size (≤50 employees) was associated with increased risk of CWP, but it is unclear whether mine size is associated with risk of abnormal lung function.

Optimization of coal recovery and production rate as a ...

For instance, given a thermal coal price of US$41.00/ton, a 1% increase in recovery for a 10 million ton coal resource increases revenue by US$4.1 million over the mine life. These gains could be even higher if the objective function can also maximize production rate so that production rate is not unduly sacrificed in the quest for higher coal recovery.

Objective To evaluate whether vascular health in young children was associated with exposure to a 6-week episode of coal mine fire smoke or environmental tobacco smoke (ETS) in a retrospective cohort study. Methods Three years after a coal mine fire in Victoria, Australia, we investigated the vascular health of children either in utero (n=75) or aged <2 years (postnatal exposure, n=96) at the ...

Lung-Function Impairment Among US Underground Coal …

The US Coal Mine Health and Safety Act became a law in 1969, establishing an enforceable federal limit on the exposure of underground miners to respirable coal mine dust. 1 The goal of the Act was to prevent the severe and lethal forms of pneumoconiosis that were prevalent at that time among coal miners in the United States. It was acknowledged that the exposure limit would not fully protect ...

Long‐term respiratory risks following exposure to relatively short periods of poor air quality early in life are unknown. We aimed to evaluate the association between exposure to a 6‐week episode of air pollution from a coal mine fire in children aged <2 years, and their lung function 3 years after the fire. Methods

Longwall Mining - an overview | ScienceDirect Topics

Thomas M. Barczak, in Advances in Coal Mine Ground Control, 2017. 1.1 Introduction. Longwall mining has had a major impact on both productivity and safety in the US coal mining industry. Many changes have occurred as longwall mining matured from its infancy in the 1970s. Much of it was experienced based, but there were also focused research efforts that addressed all aspects of the longwall ...

Effect of coal mining on vegetation disturbance and ...

24-8-2014· Comparing these figures with the amount of coal produced, this calculates the carbon release from vegetation owing to coal mining at Xinzhouyao coal mine as 77.568 g/t. Because much of the carbon in lost biomass is recycled to the soil, the biggest impact on the carbon balance of vegetation near coal mines may be attributed to a reduced ability to absorb atmospheric CO2.

Note that requirements for explosion barriers to reduce the risk of coal dust explosions at underground coal mines are not included in the Amendment Act. Instead, these requirements are being finalised through proposed amendments to the Coal Mining Safety and Health Regulation 2017 and tripartite (department, union and industry) representative work on a recognised standard for explosion barriers.
