Mar 01, 2008 Reclaiming of the stockpile is done at 1,800 tph by a portal scraper Figure 6 that works down the full length of the pile, extracting coal from one side of it onto a conveyor belt on the same side.
Apr 28, 2016 Once a stockpile has spontaneous combusted it is hard to contain and extinguish. Typically the burning coal must be spread thinly over a wide area and be allowed to cool and extinguished with sprinklers. Applying sprinklers to the surface of a coal stockpile that has spontaneously combusted is typically not an effective method.
Sep 14, 2017 Coal stockpiles emit fine particulate pollution in several ways. First, wind blowing over uncovered coal stockpiles results in fugitive coal dust emissions that are a source of PM2.5.

Sep 23, 2016 Both reclaimers and cranes move along a single rail track and therefore cannot pass each other, and handle one object at a time a stockpile in the case of a bucket-wheel reclaimer and a container in the case of quay or yard cranes. Furthermore, in coal terminals as well as container terminals maximizing throughput, i.e., minimizing the time ...
The entire former goods yard was by this time the coal merchants yard with substantial stockpiles banked up in pens made of old oil drums and a mechanical shovel for lifting the coal into the bagging machine. Coal merchants with large sail served depots such as Charringtons, warranted train load deliveries and these continue today.
In a rail served coal yard there would usually be a stockpile somewhere in the yard, in country locations and in areas outside the North East the storage facilities generally consisted of bunkers made from old sleepers, or more recently 45 gallon steel drums filled with rubble by the 1990s old car tyres filled with earth were becoming quite ...
Jan 06, 2021 Still, China is short of coal, said Wood Mackenzie, with some mills surviving on stockpiles and Mongolian coal prices increasing as the Chinese switch over.
Up to 14 of coal arriving at RBCT is bypassed directly onto waiting ships, while the rest is conveyed directly onto stockpiles. The stock yard has a capacity of 8.2 million tons with 36 grades of coal stacked in more than 92 stock piles. Stacking and reclaiming of coal at RBCT is a complex process, requiring sophisticated controls.
The quality can be assured by blending the coal within the mining operation combination of mining units, shifting heads and coal lines, on the stockyard during the stacking or reclaiming process or in the in plant storage and feeding system.

Feb 09, 2021 A reclaimer places coal in stockpiles at the coal port in Newcastle. ANZ has announced it will stop lending to the port after adopting new policies last year to manage financial risk from climate.
A random survey of 12 coal storage sites Table 13 indicated a range of 2.4 m to 11.3 m 8 ft to 37 ft in height, with an aver- age of 6 m 19.6 ft. This value is within 3 of the reported data. The surface area of the representative coal stockpile, Sp, is calculated from Equation 2 to be 19,792 m2 212,961 ft2.
Location MCNYC Coal Stockpile, Dearborn, MI. Shortly after the Junction Yard branch was constructed next to the Rouge Plant in the late 1910s, the Michigan Central used the triangle between the Main Line, the Junction Yard Branch, and the wye to Town Line for coal storage.
A steel plant had to be built in the lowlands at the Brazilian seashore inclusive of a large stock yard for coalcoke. The area consists of very soft saturated soils up to 20 m thick. Beside the high stockpiles, the stock yard includes runways for stackerreclaimers similar to the huge excavators on rails in open mining.

The coal is then loaded onto vessels for export and is generally used off-shore in steel making. Lytteltons stockpile can hold up to 335,000 tonnes of coal. By rail we can receive up to seven trains per day, comprising of no more than 30-50 tonne bottom dump railway wagons.
Jun 02, 2015 I am working on a project in Indonesia for a coal export terminal. The volatile material content in coal is 39 . I read somewhere that this is considered as high volatile and the stockpile height should be restricted to 4 m. In that case I will have to have very long stockpile. I have designed the system with 15 m heigh pile. Open to forum for guiding on best solution.
Nov 13, 2016 The rail mounted stacker reclaimer is suitable for serving two parallel stockpile, one on either side of the track rails. The machine is designed to operate with a yard conveyor for stacking and discharging at the same end during reclaiming i.e. a reversible one. Modes Of Operation Of Stacker Reclaimer 1. Stacking
The capacity of the Newcastle Coal stockyard is 6.1 Mt, assuming continuous stockpiles of coal. The effective capacity will be dependent upon the number of coal types stockpiled. Each shipper has dedicated stockpile areas to enable effective management of its coal inventory prior to shipment.
All of the coal mines on CN prepared the coal in a similar fashion. The coal was pulverized before being stockpiled and loaded which necessitated that each car be sprayed with a latex spray to reduce the risk of coal dust blowing out of the cars. Each loadout used a hopper scale to weigh the coal before it was loaded into the cars.
One coal fired power plant MinTech treated in Arizona had 1-2 fires in their coal yard every day. Once a full-body treatment program was implemented, treating the coal being unloaded at stackout, the incidents decreased to only one hot spot every 15-20 days. Thats an 85 reduction in the number of coal fires in the coal yard.
The coal stockpiles referred to in this guideline are of a size that require stockpile dozers to be used to facilitate handling requirements. In most cases these coal stockpiles are over a reclaiming tunnel. Coal stockpiles are either run of mine or washed product stockpiles created from the coal mining and coal washing processes.
Apr 01, 1999 The experimental coal piles were built at ENDESA coal storage yard in Andorra Teruel and they allowed us to test the efficiency of the periodic compaction, use of a low angle slope in the prevailing wind direction and pile protection by artificial barriers or covering with an inert layer to prevent self heating and spontaneous combustion of the coal stocked.

Bulk storage of any combustible materials leads to fire risk in many large storage areas such as waste bunkers, wood or paper stockpiles and coal storage yards.
Losses might be intended to avoid the risk of waste non-coal material, especially in high ash coals, or avoid the presence of fines. Not all discards are inert and value-free.
Coal can be stored in large quantities because of some necessities. Although stacking is generally done in open areas, there are also covered stack areas or completely closed coal silos. Produced coal is generally loaded in trucks or wagons by excavators and loaders to be transported to the storage areas.
