Finally mine geo environment of open pit mining was exhibited in detail 1 Open pit mining was the mostly used mining techniques for different types of minerals
Gibson W De Bruyn I A and Walker D J H Stability of rock slopes in open pit mining and civil engineering situations Proceedings of The South African Institute of Mining and Metallurgy International Considerations in the optimisation of bench face angle and berm width geometries for open pit mines Symposium on Stability of Rock
The ecological impacts of mining and the instability of slopes are the key factors restricting the safe efficient and low carbon production of open pit mines This study focused on the ultimate pit limit UPL optimization under the concept of sustainability by integrating consideration of the economic benefit ecological impact and slope geometry The integrated
mill tailings in a mined out open pit The evaporation/seepage ratio can be increased through the use of interior drains long term monitoring of groundwater quality can be eliminated and the open pit will not require an extensive liner Other advantages not related to groundwater are control of fugitive dust and radon emanation during mill
Groundwater management of the decommissioned pit mine was also evaluated with simulation results suggesting that backfilling the excavation would restore the groundwater level within the open pit
Historically the Talatui open pit mine has been the principal ore source for Darasun since the closure of its underground operations In 2023 the Talatui deposit yielded 104 000 tonnes of ore with the Darasun plant processing 256 000 tonnes culminating in the production of nearly tonnes of gold
This study aimed to develop and assess the feasibility of different machine learning algorithms for predicting ore production in open pit mines based on a truck haulage system with the support of the Internet of Things IoT Six machine learning algorithms namely the random forest RF support vector machine SVM multi layer perceptron neural networks
Open pit mines are becoming more intelligent and unmanned One of the core technologies for autonomous driving is high definition map technology while refined mine maps are also needed to support scenarios such as vehicle shovel collaboration loading and unloading production scheduling and traffic safety control To better serve the construction of

Step feature lines are one of the important geometrical elements for drawing the status quo maps of open pit mines and the efficient and accurate automatic extraction and updating of step feature lines is of great significance for open pit mine stripping planning and analysis In this study an automatic extraction method of step feature lines in an open pit mine
Mining activities commenced in 1901 and transitioned to open pit mining in 1914 establishing it as the largest coal mine in Asia The slope radar located on the south side of the mine provides near real time monitoring of the northern area as depicted in Fig 7 a

The design of open pit mines in China usually adopts the principle that the boundary stripping ratio is less than or equal to the economic stripping ratio to determine the pit limit Economic Stripping Ratio Reflecting the economic connotation it is the maximum stripping ratio allowed economically under the current technical and economic
Open pit mining has increased substantially over the past two decades Many currently operating open pit mines are facing the end of mine life over the next few decades and increasingly focus is
Open pit mining usually features a relatively lower mining cost higher stripping ratio and longer time to access ore [5] Underground mining on the other hand features a higher mining cost higher grade and earlier access to ore [6] [7] [8] There are currently limited tools or methods to directly optimize this interface
Closure planning is a fundamental requirement for all existing and planned future mines However there are no accepted industry guidelines for how to assess options for open pit closure or for

The Dynamic Open Pit Design is a part of the Open Pit Design module Create huge constructions of mining activities such as Final Pit Design Final Dumps Design Pushbacks and Pit Expansion for the required period
In this work we carry out a hygienic assessment of working conditions at modern ore pit mines and reveal an integrated impact of dust gas noise vibration and microclimate factors on machinery operators The classes of working conditions for employees are identified; the results of a special assessment of working conditions are provided Over the
In this study the goal is to introduce a novel approach for jointly optimising open pit mine production scheduling and ramp design Accordingly a two stage stochastic integer program SIP [Citation 25] for optimising long term open pit mine production schedules while ensuring equipment access through ramps and road is presented This differs
Open pit mining commenced in November 2011 and ceased in June 2014 upon depletion of the in situ open pit Mineral Reserve While the mining of the open pit has ceased a sizeable stockpile of open pit ore was used to augment underground production until early 2020 but has now been depleted Over the life of the open pit approximately Mt
For an open pit mine different pit limits have different pit diameters ore amounts and waste rock volumes which require different regions for mining waste dumping and tailings discharge resulting in greatly varying environmental damage Adibi et al 2015 Moradi and Osanloo 2015 Rahmanpour and Osanloo 2017 Xu et al 2014 In addition different mining
