Two years ago Coaltech started a project aimed at identifying mechanised conveyor area cleaning systems available world wide. Over 200 mini machinery manufacturers were found to exist worldwide, with a myriad of potential technical solutions amongst them. Very few seemed focused on mining applications.
Abstract For the comprehensive mechanised coal mining technology, the support design of the main withdrawal passage in the working face is an important link to achieve high yield and efficiency. Due to the impact of mining, the roof movement of the withdrawal passage is obvious, the displacement of the coal body will increase significantly, and it is easy to cause roof caving and serious ...
The products produced after the coal washing process are generally divided into gangue, medium coal, grade B clean coal, and grade A clean coal. The finished coal after the coal washing process is usually called clean coal. Through coal washing, the transportation cost of coal can be reduced, and the utilization rate of coal can be increased.
As thick rock partings delay the efficient mining of coal seams and constrain the sustainable development of coal mines, an innovative extraction method for a coal seam with thick rock parting was proposed. The coal seams were divided into different subzones according to the thickness of rock parting and then the subzones were mined by separately using three mining schemes involving full ...

19 Feb 2021 Cleaning It is no longer uncommon to see a massive road sweeping machine rumble down the arterial road of a city, or down a highway in the middle of the night. While India has begun to slowly awaken to the merits of mechanised sweepers, the uptake has been slow, despite no lack of machines designed to suit specific needs.
Unlike steel, the cement industry demands roundtheclock housekeeping with fine dust floating constantly in the air or forming a thin carpet on the floor. This calls for specialised equipment with special features to ensure that air pollution levels are maintained well within the prescribed limits. At many cement factories, cleaning up of this residue is still being done with brooms, shovels ...
Platt's roving frame, c. 1858. Cottonspinning machinery is machines which process (or spin) prepared cotton roving into workable yarn or thread. Such machinery can be dated back centuries. During the 18th and 19th centuries, as part of the Industrial Revolution cottonspinning machinery was developed to bring mass production to the cotton industry. Cotton spinning machinery was installed in ...
The extraction of thin coal seams will liberate the holdup coal reserves, increase recovery rate of coal resource and extend the mine lives. 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
India targets to increase coal production to billion by 202324 and the government has implemented a number of steps including revenue share mechanism, rolling auction, and single window clearance to boost output, Union Minister of Coal Pralhad Joshi said on Wednesday. "Coal India Limited has envisaged a coal production programme of one Billion Tonne from CIL mines," Joshi said in a ...
Physical coal cleaning processes, the mechanical separation of coal from its contaminants using differences in density, are by far the major processes in use today. Chemical coal cleaning processes are currently being developed, but their performance and cost are undetermined at this time.

Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio's bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery. 1891.

2012, the matter of damages to wagons during mechanised loading/unloading was discussed. During the meeting a Booklet titled "Damages to Wagons caused by mechanised loading/unloading" was given to all General Managers. A copy of this Booklet has since been Emailed to all CRSEs . A report on mechanised loading/unloading of BOXN wagons submitted
The average value of coal at the mine today is per ton as compared with per ton in 1923, an increase of percent. Wages, however, are 143 percent higher than in 1923. Today, the incentive for mechanization is more pro nounced than ever.

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 miners and ...
China's total coal production in 2021 exceeded billion tons, 52% of the world's total. Coal gangue, a solid waste of coal mining accounts for 1520% of coal production, when directly discharged on the ground surface as waste heaps, it occupies large areas of land and cause environmental pollution. This paper summarizes the existing gangue backfilling methods, their working ...
Coal processing or coal beneficiation uses physical (mechanical) and/or chemical methods to remove rocks, dirt, ash, sulphur and other contaminants and unwanted materials to produce highquality coal for energy in both local and export markets.
However, due to low coal, production seldom exceeding million clean tons per year, and due to smaller plowing capacity, it cannot cut hard partings including fault materials causing operational difficulties, although the latest model has 2 × 800 KW installed power and cutting speed up to m/s.
Photo courtesy: Genrobotics. With an aim to eliminate manual scavenging across the country by August 2021, the Union Government is planning to amend the law and make mechanised cleaning mandatory. As part of the amendment in the Manual Scavenging Act, to make the mechanised cleaning of sewers and septic tanks mandatory, the word 'manhole ...
The invention relates to a coal mining device and particularly relates to a coal blocking device for a fullymechanized coal mining machine of thin seams. Since a middle groove of a thin seam mining working surface scraper conveyor is relatively shallow, a coal passing space is small when the coal mining device is assorted with a thin seam mining machine, and meanwhile, coal overflows from a ...
