Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...

To achieve a successful and effective operation, the transition from open pit to underground mining requires accurate planning analysis. Numerical modeling utilizing programs like FLAC3D has been an important tool for simulating analyzing complicated geomechanical behavior connected with this shift in recent years. The use of develop model switch coal soft rocks using room pillar method is expl...

INTRODUCTION This study focused on using analytical and numerical models to develop and manage groundwater resources, and predict the effects of management measurements in the groundwater system. Movement of contaminants can be studied based on groundwater flow characteristics. This study can be used for prediction of ion concentration and evaluation of groundwater pollution as the theoretical ...

In order to reduce the large rocks produced by blasting of hillside open-pit mine with heterogeneous and complex rock mass in arid area, based on lithology characteristics Dabancheng Limestone Hillside Open-pit Mine Hongshun, Xinjiang, key technology for homogeneous is proposed this paper. We can conclude from experiment that (1) it preferable have a detonation network realizes multi-stage mill...

The open-pit mining problem is to determine the contours of a mine, based on economic data and engineering feasibility requirements in order to yield maximumpossible net income. This practical problem needs to be solved for very large data sets. In practice, moreover, it is necessary to test multiple scenarios taking into account a variety of realizations of geological predictions and forecasts...

This paper proposes a new mathematical model for the open pit mine planning problem, based on continuous functional analysis. The traditional models for this problem have been constructed by using discrete 0−1 decision variables, giving rise to large-scale combinatorial and Mixed Integer Programming (MIP) problems. Instead, we use a continuous approach which allows for a refined imposition of s...

For the purpose of production scheduling, open pit mines are discretized into threedimensional arrays known as block models. Production scheduling consists in deciding which blocks should be extracted, when they should be extracted and how each extracted block should be processed. Blocks which are on top should be extracted first, and capacity constraints limit the production each time period. ...

In this study, a three-dimensional finite difference numerical model of the Jinfeng Gold Mine, including surface topography, ore body, shafts, and main faults, was built to estimate shaft stability deformation induced by underground mining transferred from open-pit mining. Satellite monitoring data displacement at several points used calibrate model. The sequence excavation filling in simulatio...

In order to carry out an open pit mining operation, planners must periodically prepare what is known as strategic mine plan. This is a tentative production schedule for the remaining life of the mine that defines which area of a mining reserve will be extracted, in what years this extraction will take place, which resources will be used for the extraction, and how the extracted material will be...

In this study, a hybrid intelligent model has been designed to predict groundwater inflow to a mine pit during its advance. Novel hybrid method coupling artificial neural network (ANN) with genetic algorithm (GA) called ANN-GA, was utilised. Ratios of pit depth to aquifer thickness, pit bottom radius to its top radius, inverse of pit advance time and the hydraulic head (HH) in the observation w...
