Pit Slope Failure Problems in Goan Iron Ore Mines,

2008-8-14  The problem of open pit slope stability is a matter of concern when the mining operations go deeper followed by weak strata conditions. In Goa iron ore mines the problem of slope instability has been faced by several mines, after the on-set of monsoon. A review of case studies available on the subject demonstrates that the ground displacement, stress redistribution, effect of ground water, low

Transition from open-pit to underground in the case

2014-5-7  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.

Assessment of backbreak due to blasting operation in

2016-3-25  One of the major problems related to blasting operations in open pit mines is the formation of cracks on the benches behind the last row of blast holes (backbreak). Prediction of backbreak plays an important role in the safety of open pit mining and the reduction of the detrimental effects resulting from blasting operations. In this study, we have tried to develop predictive models for

Phase Planning for Open Pit Coal Mines through

2021-2-11  This paper presents a phase planning method specially designed for coal deposits with nearly horizontal, bedded coal seams. The geology of this type of deposit is modeled into a column model, instead of a block model, to avoid coal-rock mixing in blocks. A nested pit generation algorithm is developed for producing a series of nested, least-strip ratio pits with a column model as its input.
