Mine stockpile design to minimise environmental impact J. E. Everett Faculty of Economics and Commerce, The University of Western Australia Abstract In Western Australia, iron ore is extracted from inland mines and railed to a port, where it is loaded onto ships for export. Quality depends upon uniform

l Inplant coal handling systems. Stockyard management description In order to achieve a fully automated operation from a central control room the operator must know how much coal, and of what quality, is at what place, and when whether it is in a surge bin, on a belt or on the stockpile. These requirements can be met by
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.
Improving fundamental stockpile management procedures P. Keleher D. Cameron Coal Quality management and the control of the flow of coal through complex mining preparation and transport phases of standard mining operations has assumed greater importance over recent years.
Stockpile serves as a buffer between the delivery and processing, as a strategic stock to shortterm disturbances or long term. Stockpile also serves as a process of homogenization or mixing coal and to prepare the required quality. Besides the above objectives in the stockpile is also used for coal memcampur order homogenization as needed.

Mine Safety and Health Administration Hazards of Coal Stockpiling Operations DVD501 1994 This video shows what happens when miners or equipment operators are working on a surge pile and the
The basic stability and moisture processes in coal stockpiles are described in detail to provide an understanding of the associated stockpile problems and to provide a framework for interpretation of the results of laboratory testing. Results are presented for extensive laboratory physical testing of moisture and strength properties of five
Some of the requirements change if the stockpile is covered and if explosionproof 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.
A coal preparation plant CPP also known as a coal handling and preparation plant CHPP, coal handling plant, prep plant, tipple or wash plant is a facility that washes coal of soil and rock, crushes it into graded sized chunks sorting, stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
