#0183;#32;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

Technical Aspects of Mining. 1. Drilling and blasting. By far the bulk of rock excavated in mining globally is broken by drilling and blasting. Mining is the largest consumer of civil explosives. Mining explosives are substances which detonate to produce a highintensity shock wave and large volumes of gas which, being confined in a hole, expand

Posted by Matthew Bliss, Deputy Director How Technological Innovation is Impacting the Mining Sector. Rapid advances in technological innovation, including through automation, digitization, and electrification, are having a fundamental impact on the mining sector.
Through the middle of the 19 th Century, the coal industry expanded and spread. Ohio produced over a million tons of coal by 1853, and by 1861 coal mining had expanded to 20 states. At the time, coal mining operations remained small businesses. A skilled miner could employ a few laborers to extract coal close to the surface.
Technical Aspects of Mining. 3. Ventilation of underground mines. Coal mines are particularly susceptible to the presence of natural gases. These include toxic gases such as hydrogen sulphide (H 2 S) but the most significant are flammable gases, of which the most common is methane (CH 4).
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
