We propose, implement, and test two approaches for dispatching trucks in an open-pit mining operation. The first approach relies on a nonlinear optimization model that incorporates queueing effects to set target average flow rates between mine locations. The second approach is based on a time-discretized mixed integer programming (MIP) …

rolling and sliding phases (V arnes, 1978). Due to the high. motion velocities, which render any warning equipment. useless, rockfalls are one of the major hazards in open-pit. mines. Rockfalls ...
Coal mining, particularly open cast coal mining, causes disruption and degradation over wide regions. Post mining restoration has vital importance in order to minimize the impacts on the environment. Besides the ongoing reclamation activities, it is important to re-evaluate the health of planted species until the vegetation is self-supporting.
A dynamic optimization method was created to address the production schedule issue in an open-pit coal mine while taking into account the characteristics of the fuzzy structured element. The fuzzy mining capacities of all "geologically optimal push-back bodies" were then examined using the moving cove method. One of the most crucial …
The study area of open cast mine is there exist three main coal seams in the area, viz, Top seam, Middle seam and Bottom seam. All the seams in the above mines were extensively developed/depillared by caving/stowing. Even after working these four ... creation of models for soil and/or rock slopes and solution of their stability condition.
Chapter Particle dispersion within a deep open cast coal mine Sumanth Chinthala & Mukesh Khare Indian Institute of Technology Delhi India 1.0 Introduction Dust generation and its dispersion has been the major concern in ambient air quality in deep cavities such as open cast mines. Major mining activities in deep open pit coal mines range from ...

numerical model studies with the simulated materials, geometry etc for typical opencast coal mine, the factor of safety turned out to be more than 1.5, and considered as stable as per the recent ...
Expanding open-pit mining towards larger mining scales and greater stripping depths increases the potential risks of landslides on high and steep slopes, endangering human life and property. Therefore, it is of great significance to accurately reveal the main controlling factors and identify the key dynamic parameters to …
In case of PM10 its dispersion is additionally affected by intertial and dynamic forces acting on the particulates acting on them. Open cast coal mining involves various operations e.g overburden ...
Coal mine a life of mine extension project was approved for implementation when export coal prices were on the low end of the price cycle. The dynamic simulation of the full materials handling value chain conducted during the project feasibility study in 2016 was of utmost importance and provided assurance to the project review team that annual ...
The present study aims to bridge this gap by simulating the effects of land-use and topographical changes due to coal mining on surface runoff in the Jamunia basin of Jharkhand, India. The derivatives of digital elevation model (DEM) have been used to simulate the changes in topography of the study area and the runoff has been calculated …
In order to improve dust pollution control in opencast coal mines, this study combines prospect theory with evolutionary game theory, analyzing the evolutionary …
The modelling method considered the dynamic, stochastic and systemic characteristics of the operation. The research conducted on the history of simulation in the mining industry confirmed that the simulation approach and method described in this paper has not been previously used. See more
The Kolubara Coal Basin is the largest coal-producing area in Serbia. It is administratively comprised of several open-cast mines: Field A, Field B, Field C, Field D, Field E, Field F, Field G ...
Optimum design of the open cast mine pit slope is important from both stability and economic point of view. Hence, the aim of the design of an open cast mine is to provide the best possible outline of excavation with respect to safety, ore recovery and financial return [].The most crucial part of the design is to find the optimum slope angle …
In this paper, Case studies of reliability and maintainability of HEMM used in an open cast coal mine in India are discussed based on the principles of reliability centred maintenance (RCM).
In case of PM 10 its dispersion is additionally affected by intertial. and dynamic forces acting on the particulates acting on them. Open cast coal mining. involves various operations e.g ...
Slope stability analysis forms an integral part of the opencast mining operations during the life cycle of the project. 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.

Along with changes in land-use, open cast coal mining also changes the topography along with the drainage pattern of the region. It was observed that majority of the increase in opencast mining area (53%) and built-up area (85%) took place between 2003 and 2010 for the present study area (BCCL Annual Report 2013–2014).
The selected model boundaries in the north, east, south and west are far enough from the existing open cast projects to minimize potential boundary effects during the mining-phase simulations (Table 1). In addition to the effects of dewatering and pit-refilling within the quarry area, the model domain was also selected to infer the potential ...
