At Ha Lam Coal, Vinacomin has invested in a synchronous mechanised longwall furnace with the largest capacity ( million tonnes of coal/year). Investing in mechanisation also helps minimise the amount of waste after the production process. With these advantages, coal enterprises have made efforts to invest in environmental protection projects.
"Mechanisation definitely improves labour efficiency," says Ralph Sunil, VPAdministration, Essar Steel Ltd, Gujarat, "as the machine can be put to use during the day shift and also the night shift." Around 40 labourers were cleaning in a single shift the 8km road stretching across the township of the Hazira plant.
Longwall Miner. Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area.
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.

Only 821 husbands were unemployed, undermining some critics' claim that women worked, while their spouses boozed in the nearest pub. There was evidence that factory women's 12hour shifts endangered their children's health. Mary Woodhouse, a midwife at the Manchester LyingIn Hospital, told an investigator in 1833 that factory women gave ...
Mundra Thermal Power Project is a coalbased thermal plant with a power generating capacity of 4,620MW. The plant is located in the Kutch district of Gujarat in India near Mundra Port in Mundra Power Special Economic Zone (MPSEZ). The project is owned and operated by Adani Power. Construction works for the facility started in 2008 and the ...
Published On Oct 24, 2019 at 05:43 PM IST. NEW DELHI: Stateowned CIL on Thursday said it will switch over to mechanised transportation of coal through piped conveyor belts in its large mines by 202324, replacing the existing road movement of the dry fuel. Piped conveyor belt transportation is a covered system for movement of coal and thus ...
A mathematical hydraulic support selftracking model for threemachine cooperative mining is proposed to address low efficiency and difficulties in strategy evaluation of a fully mechanized coal face. The proposed model uses the coordinates and traction speed of the shearer to calculate the frequency of the circular hydraulic support and realize the coordinated operation of the threemachine ...
McLanahan equipment can reduce the amount of fine coal waste that is destined for the settling pond or gob pile by converting it into a dry, dripfree product that is safer and easier to handle. In some cases, these tailings can be repurposed as a saleable product. McLanahan equipment can also help coal producers struggling with an insufficient ...
This is when the plant would ask for a cleanup job. The acid and the sludge have a pH of 0 to 1 which means it is highly acidic and is extremely dangerous for human entry. ... The Delhi Jal Board launched the first batch of its mechanised sewer cleaning machines. Around 200 customised machines are expected to be deployed to help in tackling ...
(a) 0 to 100 ohms for underground coal mines. (b) 0 to 100 ohms for other applications. Equipment # 8. Crimper: A crimper is a paid of pliers to crimp or press the end of a plain detonator tube on a safety fuse inserted into it so that the fuse cannot come out of the detonator. It is dangerous to crimp the tube end with teeth. Equipment # 9.
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 ...

Combination machines for very large warehouses: Sweeping, scrubbing and vacuuming in one machine. We recommend using combination machines in very large warehouses with areas of over 10,000 square metres. In such areas, machines with dust suction and a filter area of up to 10 square metres are used.
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 ...
Coal Cleaning Equipment. The relative performance of coal washing equipment, or the effectiveness with which any type or make of equipment removes impurities from coal, has been most difficult to evaluate in the past. The most widely used yardstick is the Frazer and Yancey efficiency formula developed in 1922, but Yancey in a later article ...

China suffers the worst coal mine disasters in the world. Lots of miners lose their lives or suffer occupational injury. Fortunately, China is developing vigorously intelligent coal mining, which is the combination of traditional coal mining and the latest technology. Mining expects to relieve or solve coal mine safety, health and intensive labor issues and ensure energy security by applying ...
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 ...
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.
