open pit mining in india a case study of iron ore mine

DESIGN OF STABLE SLOPE FOR OPENCAST MINES

In Indian mining conditions, slope design guidelines were not yet formulated for different types of mining practices and there is a growing need to develop such guidelines for maintaining safety and productivity. Till date, most of the design methods are purely based on field experience, rules of thumb followed by sound engineering judgment. During the last four decades, the concepts of slope

Case Study Iron Ore Mine Optimisation MEC Mining

An open cut iron ore mine required a detailed mining sequence incorporating current short- term plans as well as an extended mine plan tailored to an optimised pit shell. The ore body contained complex structures and the mining sequence had to follow prescribed operational priorities. The client was committed to ramping up production significantly in the first 12 months, making detailed mine

Stochastic Open-Pit Mine Production Scheduling: A Case

Production planning decisions in the mining industry are affected by geological, geometallurgical, economic and operational information. However, the traditional approach to address this problem often relies on simplified models that ignore the variability and uncertainty of these parameters. In this paper, two main sources of uncertainty are combined to obtain multiple simulated block models

Pit lakes are a global legacy of mining: an integrated

01/12/2016· Pit lakes form when open-cut mining operations cease and the remaining pit fills with ground, surface and rain water. Mine pits, and therefore pit lakes, tend to have high depth-to-surface-area ratios with relatively flat bottoms and steep sides in order to minimise resource extraction costs (n.b., for the purposes of this review we are focussing on large mineral/coal mining pits as in Figure

Open Pit Mining an overview ScienceDirect Topics

Open-pit mining is probably most advanced because of developments in mining low-grade copper deposits and iron ore. It is suitable for much of the resource if it is done on a large scale and will allow low-cost removal of most of the resource. Research needs include studies of slope stability, dewatering on a large scale, methods of placement of spent shale in the pit, and a plan for location

Transition from open-pit to underground in the case of

Geological and economic modeling of an ore body and also optimization of the depth at which transition is made from open-pit to underground mining is an important part of the mining design process in large and massive deposits. In this paper, a geological block model of Chah-Gaz iron ore deposit located in Iran was first created based on iron ore cut-off grade. Then with considering the

Green Mining Massachusetts Institute of Technology

Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002). In situ mining (see mining solution page) can be more environmentally friendly
