Horizontal mineral deposits with relatively thick sediment overburden advisable to practice using transtoptless overburden removal technology, that is using a powerful stripping equipment draglines. The main advantage of this technology is the placement of overburden directly into cut goaf, significantly reducing the rented for the waste dumps disposing areas, and reduce the costs of mining ...
01/03/2019 Overburden removal and disposal operations in quarry pits are affected by geological, geotechnical, environmental and logistic issues. Methods for handling the materials have to be selected on the basis of the amount of the volume, on the distance from excavation to discharge points and on the consistency of the materials. The possible reuse or reclamation of the site is also to be ...
The overburden is dumped according to its chemical characteristics, mainly acid potential, to ensure optimal rehabilitation outcomes. Production Phase. The mining process begins with clearing of vegetation, topsoil removal and stockpiling, followed by laterite removal and stockpiling. Vegetation removal involves harvesting of any commercial forest products by the Department of Conservation .

Removal and placement of overburden is a major cost in the mining operation. Mining techniques. Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining ...
Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an exhausted mining site to a semblance of its appearance before mining began.
overburden/interburden removal must be done in order to recover the coal reserve underneath. The shovel capacity used to mine overburden varies between 27 to 33 m 3 and haul dump trucks with a payload capacity range 80 – 360 t. Furthermore, controlled blasting with the ANFO base explosive is performed for excavating the overburden/interburden and extracting the coal seams which have a ...

Rehandle occurs when overburden is handled twice and sometimes multiple times during excavation and spoil placement. Having 0% rehandle of the original inplace overburden is not achievable because of inherent design requirements of surface mining such as ramps into the pit and mining conditions such as sloughing ground that covers the coal. Simulating alternative mine plans and anticipating ...

Waste removal and placement is a major cost to the mining operator, so a detailed characterization of the waste material forms an essential part of the geological exploration program for a mining operation. Once the analysis determines a given ore body is worth recovering, development begins to create access to the ore body. The mine buildings and processing plants are built, and any necessary ...
The Morris Sand and Gravel Overburden Removal project in Morris, IL, involved removing 200,000 CY of topsoil in order to reach the sand layer, which was put on barges on the Illinois River and sent to various batch plants across Illinois.
