I discuss techniques used for mapping coal seams and geotechnical characterisation. Overview on the application of geophysics in coal mining
Abstract. The problems of information redundancy and sharing are universe in coal mining equipment management. In order to improve the using efficiency of About one quarter of the coal produced in Australia is by underground mining methods. The most commonly used underground coal mining methods in Geological and geotechnical aspects of underground coal mining
The range of applications in both surface and underground mining is extensive. Applications include coal seam mapping and geological fault detection, The history of coalfield geology and mine geology IT applications is over 30 years, which is gaining remarkable achievements. This paper sheds light on the Development of coal geological information technologies in China
In modern‐day mining there are two basic methods of mining coal: underground mining and opencast or surface mining. In most coal‐producing countries, Dissolved organic matter (DOM) regulates and controls the transformation and bio-availability of metals in coal mines. Water samples were collected Composition and Sources of Dissolved Organic Matter in
Modes of coal mining. The thickness of coal seam, depositional angle, terrain, and mechanics of surrounding rocks are basic factors that are considered when The operation of intelligent coal mining in complex geological environment is still unable to realize automation. In order to realize the autonomous cutting of fully mechanized mining equipment and improve coal production, a mining and transportation equipment dynamic advancement path planning method based on spatial A Virtual Planning Method for Spatial Pose and Performance
Shortwall mining, a method currently accounting for less than 1% of deep coal production, involves the use of a continuous mining machine with moveable roof supports, similar to longwall. The continuous miner shears coal panels 45–60 m (150–200 ft) wide and more than a half-mile long, having regard to factors such as geological strata.The technology of coal mining has gone through continual evolutions and several revolutionary changes which transformed the methods, equipment, and productivity over the decades. In recent years, advances in technology focused more on the use of communication systems, automation, and data sciences for the health and safety of the Advances in coal mining technology and sustainable mining

More than 20 years of studies on green mining in China have witnessed theoretical and technological progress in water-protective mining, co-extraction of coal and gas, surface subsidence mitigation, mine waste reducing and recycling, mine dust control, etc. In this context, this Special Issue welcomes review articles, research articles, andCoal 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.Coal Geology Geoscience Australia
The precombustion washing and washability of coal are increasingly gaining attention as a clean coal technology in China. In this study, the raw coal was collected from different coal seams in the south of Qinshui Coalfield, and flotation experiments were carried out in the laboratory after simple crushing. X-ray diffraction was used for qualitative analysis of the The key parameters used in CO 2 sequestration potential evaluation in this research are coal exploration engineering data, mining geology data, experimental test data, and the literature (Table 2). The mining depth is 200–1000 m; therefore, the buried depths of unexploited deep coal seams are ≥1000 m, and producing and abandoned mines areEvaluation of carbon dioxide geological sequestration potential in coal
This mining method has been practiced since the late 1950s (Plass 1967) but underwent significant expansion during the 1990s for reasons that included the expanded scale of mining equipment and coal processing facilities (Copeland 2015). Historically, mountaintop mines pushed or otherwise placed much of the mine spoils on Coal Geology. Coal Geology, In: Robert A. Meyers, Editor-in-Chief, Encyclopedia of Physical Science and Technology (Third Edition), (New York, Academic Press), Pages 45-77. Risk is a necessary element in successful coal mining because it is not possible to mine coal, by any method, in any location without accepting some degree of risk.

Geophysical logs can be used not only for qualitative interpretation such as strata correlation but also for geotechnical assessment through quantitative data analysis. In an emerging digital The process of coal mining results in a lot of waste which include overburden coal spoil materials that lies above an area that lend itself to economic exploitation such as rock soil and ecosystem(PDF) A Review of Geology and Coal Mining In South
the basis of analyzing the structures and internal relations of coal mining equipment knowledge, taking OWL as ontology construct language, the ontology model of coal mining equipment knowledge is built with the help of Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to Reading: Mining Geology Lumen Learning
The modern mining process itself is a highly mechanised operation, and the selection of the mine layout to optimise equipment use is based on the mine design, to which geology is a major input. In modern‐day mining there are two basic methods of mining coal: underground mining and opencast or surface mining. In most coal‐producing mining, process of extracting useful minerals from the surface of the Earth, including the seas.A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic substance, coal, is often discussed as a mineral as Mining Definition, History, Examples, Types, Effects, & Facts

With the implementation of the fully mechanized thin coal seam mining technology in highly gassy mines, it can speed up the mining of methane releasing coal seams, achieve a balanced extraction of thick and thin seams and, ultimately, reach the goal of safe mining operations. 2.The development of rock tunneling technology and equipment is directly related to the ability and safety of coal mine production.With the rapid development of comprehensive mechanized coal mining technology,the advancement speed of the mining face is getting faster,and the requirements for the speed of roadway drivage are getting higher.The Tunnel boring machine （TBM） in coal mine and its
