·Deep learning is a sub field of artificial intelligence that combines feature engineering and classification in one method It is a data driven technique that optimises a predictive model via learning from a large dataset Digitisation in industry has included acquisition and storage of a variety of large datasets for interpretation and decision making This has led
When mine dewatering pumps break down production can be disrupted This paper explores solutions based on continuous improvement methodologies for dewatering underground mines By procuring pumps within a hire agreement rather than through purchase or lease arrangements miners can test new generation dewatering pumps and continuous
·On the other hand seven mining operations use raw seawater with capacities of between 5 Compañia Minera Tocopilla and 1500 L/s Antofagasta Minerals Currently 15 projects for the installation of new desalination plants are in different stages Stand out the projects of Coloso BHP Billiton plant at start‐up stage for 3200 L/s and
·during mining operations The water control methods are aimed at the improvement of mining efficiency and safety reduction of costs of mining and mine reclamation and at the limitation of the probable hydrologic consequences of the mining activities A well designed and implemented water management control system for an underground mine
The use of tunnel boring machines in some mining operations has been limited because they are not very mobile are difficult to steer and are completely inflexible in terms of the shape of the mine opening Tunnel boring machines are being used more often for mine entry as in the development of a palladium platinum mine in Montana
DEGRITTING EQUIPMENT Effluent entering any sewage treatment plant contains a certain amount of inorganic grit These serve no purpose in the plant s biological treatment and requires removal These are low lift high volume pumps generally used in the wastewater and mine water treatment industry They are either belt or gearbox driven
The air lift pump mounted above the grit chamber uses periodically dedicated blower air compressed air and wash water injection to move the grit slurry through the pipeline and into a grit classifier for further The Self priming grit pumps mounted above grit chamber has a tungsten coated recessed impeller that operates periodically extracting grit from the lower
·Mining activities can be classified into five classes based on their respective properties Coal mining oil and gas extraction metal ore mining quarrying non metallic mineral mining and mining support operations are some of these operations The majority of mining waste comes from surface operations but subterranean labour also contributes
·This research study examines the impact of shifts and lunch breaks on mining operations particularly focusing on delays in hauling equipment used to supply extracted material to crushers These delays significantly reduce productivity averaging below 80% during regular working hours and adversely affecting mine profitability To address this issue a Q learning
·Paragraph 46 of the JPOI called on governments to a support efforts to address the environmental economic health and social impacts and benefits of mining minerals and metals including workers health and safety; b enhance the participation of stakeholders to play an active role throughout the life cycles of mining operations
·Rock support is a common practice in mining operations especially in underground openings The term rock support is widely used to describe methods and materials used to enhance stability and maintain the load bearing capacity of surrounding rocks in underground excavations Hoek and Wood 1987 A rock support is installed to hold
·4 Definition of Mine Dewatering Dewatering and groundwater control forms a vital part of many mining projects Most open pit and underground mines will extend below groundwater level Poorly controlled groundwater can impact the safety and efficiency of mine operations Mine dewatering is the process of controlling and managing surface water and
·Mining is an industry where communication is the key and any gap could be disastrous for business and human lives Cellular Internet of Things IoT ensures cost optimization efficient communication in mining operations and high revenues while keeping the worker s safety intact
·The development of a mining operation can significantly alter the natural flows and quality of water in a region Large scale movement of material and the development of mining voids can result in significant alterations to natural water flow pathways through an area When mining takes place in areas where water is scarce mine water
·Carbon degritting is the process of cleaning used carbon in minerals processing by separating the carbon from the grit based on density and reintroducing the cleaned carbon into the mining operation
·Pumps are therefore one of the most used machines in mines today This article will review the concepts of mine water and mine water management as well as the most common pumping applications The definition of mine water is that it is not a slurry generally it is considered to contain <50g/1 of solids
·This part is primarily aimed at surface drilling operations during remote exploration although many standards may be applicable to other exploration activities and near mine drilling for ore delineation Where the term verify is used in the guideline intent it implies there is a regulatory requirement for compliance with the standard
·The three important factors showing the significance of understanding to manage mining operations are raising demand for metals and minerals leading to huge costs and investments in mining the contribution of mining to national economies and the type of mines This chapter is an introductory chapter to the world of mining its origin its
