Plant Design: Trends in Coal Pile Design

Mar 01, 2008· The key elements of the final design were a longitudinal stockpile and a rail-mounted, bucket-wheel machine (Figure 4) that can stack coal at 1,500 tph and reclaim it at 2,200 tph.

Guidelines MDG 28: Safety requirements for coal stockpiles

Where there is a change in the design parameters of the coal stockpile such as stockpile or reclaim capacity, or a change in the way the system is operated, there is a possibility that the change could result in a risk to people, equipment or the environment.A review of the hazards and risk control

Management of coal stockpiles, CCC/23 IEA Clean Coal Centre

Stockpile management is an important part of the coal handling process from mine to customer. Virtually all coal producers and consumers make use of stockpiles at their facilities, either to serve as a buffer between material delivery and processing, acting as a strategic stock against supply interruptions; or to enable coal blending to meet

Stockpile an overview ScienceDirect Topics

Six stockpiles of aggregates (19.00, 9.50, 4.75, 2.36, 0.30, and 0.075 mm) were used to produce the base and modified asphalt mixtures, where stockpiles were coarse aggregates and others were fine aggregates. The Superpave uses the nominal maximum aggregate size (NMAS) of the aggregate to categorize mixtures and define graduation requirements. In this study, the nominal maximum particle

Different Types of Coal Storage Methods Hindustan Alcox

Dec 27, 2019· In a Coal based captive thermal power plant, proper storage of coal plays a vital part for effective running of the power plant. The main purpose of storage of coal is to maintain the coal stock for numerous days; therefore the plant is not required to be shut down due to failure of usual supply of coal and to permit the choice of date of purchase allowing the management to take advantage of

Prevention and Control Module for Spontaneous Combustion

Size and area of stockpile should be based not only on estimated tonnage but also on design principles of stockpile management. Proper dimensioning of stockpiles helps negate weathering of coal. Just dumping the coal in a big pile might lead to problems. Rather coal should be packed in horizontal layers of about 1.3 to 3 feet high followed by

Prevention of spontaneous combustion in coal stockpiles

The spontaneous ignition of coal stockpiles is a serious economic and safety problem. This paper deals with oxidation and spontaneous combustion of coal piles laid in coal storage yard and the

Even when it's sitting in storage, coal threatens human health

Sep 13, 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. Second, coal

A new criterion to design reactive coal stockpiles

Aug 01, 2009· This paper proposes a new criterion to design the self-heating coal stockpiles. The generated heat can be removed if air is blown to the self-heating stockpile. At the same time, introducing more air to the system boosts the aforementioned chemical reactions. Hence, there is a tradeoff between the two opposing effects.

Mine stockpile design to minimise environmental impact

Keywords: quality control, decision support, mining, stockpile design, intelligent stacking/reclaiming, forecasting, simulation. 1 Introduction Iron ore from inland mines is railed to port, where it is crushed, separated into lump and fines products and stored onto large stockpiles. Ships are loaded for

Methods of Stacking and Reclaiming Coal Piles Everything

Blend­ing efficiency within the stockpile is poor. In addition to the reclaimers, some other types of mobile handling equipment play a role in stacking/ reclaiming coal at a smaller volume than the above mentioned reclaimers do. Front-end loaders and bulldozers are used to compact the coal and to move coal from reserve pile to live pile.

NEW REQUIREMENTS FOR MINE DUMPS AND STOCKPILES

Registered engineers must design stockpiles. Under the MPRD Regulations, stockpiles had to be designed by a ‘competent person’. The Mining Residue Regulations now require that this be done by a civil or mining engineer, registered under the Engineering Profession of South Africa Act 114 of 1990.

BEUMER Group helps coal miners with environmental impact

Some of the requirements change if the stockpile is covered and if explosion-proof equipment is needed. Hard coal is very susceptible to spontaneous combustion, which is why the height of the stockpile must, in certain cases, be limited. Depending on the customer, stockpile dimensions and design can vary.
