Respirable coal mine dust is a hazard in underground and surface coal mines and in coal-processing facilities. It is a mixed dust, consisting mostly of coal, but can also include silica, clay, limestone and other mineral dusts. The composition of coal mine dust varies with the coal seam, the composition of the surrounding strata and mining methods.
Normally associated with underground mine fires. HAZARDOUS WATER BODY Any strip pit with impounded water, regardless of depth or surface area, that is considered an attractive nuisance and is located within close proximity to a populated area, public road, or other areas of intense visitation.
The effects of mining coal on the environment. There are 2 ways to mine coal – Strip Mining and Underground Mining – both ways have their own impact to the environment and health. We know it but coal is such a cheap energy source that we don't want to let go of it. The negative effects of coal mining cannot be disputed:

Prescribed Hazard The Mine Health & Safety Regulation 2007 requires mines to conduct OH&S risk assessments in relation to certain high risk, prescribed hazards associated with ground instability, inrush, atmospheric contamination, mine shafts, conveyors, earth moving machinery, fire, explosives, electrical work and mine roads.
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 - a pit, and the ...
Rock dusting to prevent coal dust explosions has been in widespread use in U.S. underground coal mines since the early 1900s. Underground coal mining technology has changed significantly over this same time period, becoming highly mechanized and produces finer coal .
The mining district of the State of Guanajuato has been one of the main producers of silver nationally through the years and as it is a state with a large number of air and land transport routes it has become an investment center for mining companies. Underground mining is one of the main economic activities of the state and it has led to the ...
NSW code of practice: Strata control in underground coal mines Scope and application This code is a practical guide to assist the mine operator to identify and control strata failure hazards as part of developing and implementing a principal mining hazard management plan, as required under the WHS (Mines) Regulation. This code applies to the
Mine safety is a broad term referring to the practice of controlling and managing a wide range of hazards associated with the life cycle of mining-related activities. Mine safety practice involves the implementation of recognised hazard controls and/or reduction of risks associated with mining activities to legally, socially and morally acceptable levels.
This chapter provides a brief description of the characteristics of the coal industry in the United States, presents an overview of coal extraction and processing methods, and discusses the major issues associated with coal mining and processing.
Coal mining deep underground involves a higher safety risk than coal mined in opencast pits, due primarily to problems associated with mine ventilation and the potential for mine collapse. However, there are safety risks associated with all forms of coal mining, not least because of the heavy machinery utilised in coal excavation.
Subsidence Caused by Underground Mining. Subsidence associated with the underground extraction of coal and minerals is a geologic hazard with a human twist. After a resource is removed from the ground, there may not be enough remaining material to support the roof of the mine.
Mine Fires: Mine fires create surface hazards in abandoned coal mine areas. As fires burn within the seam, fissures can open to the surface delivering deadly gases into the atmosphere. The area around the fissure may not be capable of supporting the weight of a human or vehicle, and may collapse into the burning coal or the mine void.
Issue. Underground mining, by its nature, presents a range of health and safety hazards that are different from those in other sectors. Some hazards, such as ground instability, are inherent in the underground environment.
