Dewatering processes in sishen mi e

The abovementioned process will form the basis of the proposed methodology for a dewatering system design process and each of the ten elements will be discussed in more detail in the following sections. 3.1 Statement of the problem There are three main objectives of an effective dewatering system on any sub surface mining operation, namely to:

the dewatering bunkers, where it remains for about four hours before being stacked on the fine product blending beds. Jig construction and control The jigs at Sishen Iron Ore Mine are under-bed pulsating jigs that are fully PLC-controlled. All the jigs are 3 m long, and the width varies from 4

The Sishen Iron Ore Company (Pty) Ltd (SIOC) proposes to direct surplus groundwater generated from the de-watering process at the Kolomela Mine into aquifers located within the Groenwaterspruit to the east of the mine. The need for this has arisen because the mine uses relatively little water in comparison to the dewatering process, and Sedibeng

Jul 18, 2013 Jul 18, 2013 Sishen mine is a single pit operation with an opencast mineable reserve of 895 Mt. The Sishen orebody is thicker, more continuous and significantly larger than the Sishen South deposit. ... Processes of laterisation and even basinal dewatering have been proposed to explain this supergene enrichment process. The exact mechanisms and events which

Introduction to dewatering: The process of dewatering is used for the foundation trenches ground of the high water table, water-logging area. The excavations are carried out by dewatering the sub-soil water and water must be pumped into an area filled with water for which the foundation is to be excavated.. In a waterlogged area, at the time of excavation timber and strutting are very

Our Sishen and Kolomela mines continue to manage issues of concern among certain local farmers regarding mine dewatering that potentially affects the availability of groundwater. In 2017 we have been negotiating the purchase of three farms around Sishen in order to create a buffer zone. Kolomela mine artificially recharges clean mine water to the

Dust is controlled through a chemical suppression process. Dewatering : Studies are being conducted to determine the impact zone of dewatering activity on neighbouring farmers. Sishen Mine maintains ongoing consultation with affected farmers and the Department of Water Affairs and Forestry (DWAF)

Sishen ensures that most of the clean water dewatered from the aquifers is discharged into a regional water supply network. The mine effectively recycles mine-affected water for use in the process plant. The volume and quality of the water that is allowed to be discharged by our operations is predetermined through regulatory processes

and the application of this workflow at the Sishen iron ore mine, South Africa, is presented as a case study of the evaluation process. Key words: Dewatering, Well Placement technology, well trajectory, rate of penetration Introduction The majority of large open pit and underground mines require dewatering as part of the mining operation
