· Mining method selection The mining principles and methods have evolved to meet the geomechanical and operational problems of various cases Final choice of mining method will reflect both the engineering properties of the orebody and its setting and the engineering attributes of the various methods such as mining scale production rate
·Developing some models to predict the uniaxial compressive strength of various sedimentary rocks Case studies Large dam site and mine in Southeast China This method incorporates the principles of fuzzy logic which allows for handling uncertain or imprecise information The formation process including sedimentary environment
processes of change During the gold rush some migrants brought mining skills and technologies that were highly applicable to the extraction of gold While the contribution of Cornish miners to hard rock mining is well known ancient Cornish traditions of working shallow alluvial minerals also proved relevant in the colonies
·Sedimentary process modeling evolved from an academic exercise to practical applications from the 1970 s to this day The SEDSIM model developed at Stanford in Computer modeling of sedimentary processes started in academia as a method of enhancing the quantitative understanding of the processes of erosion transport and
·The mine has an elevation ranging from 447 to 584 m with a slope ranging from to 59% In Morocco phosphate ore is recovered using open pit mining Extraction is carried out using the strip mining process This process entails cutting the deposits into panels and separating the panels into 40 m ditches Chlahbi 2023 The Benguerir
·Mining is carried out by open cast method of mining which is taking place at both large scale and small scale levels The limestone mined is used chiefly for the manufacturing of cement lime and
·The evaluation of the water richness of the clastic rock aquifer on the roof of the mining coal seam mainly included the following steps 1 By using empirical formulas and GRNN neural networks
·The high costs of opening a mine and equipping it is a reason why a good extraction method must be used in the beginning of the designing stage; because reforming or changing the mining method after the beginning of the project can be quite time consuming and expensive Balusa and Singam 2017 Thus the proper extraction method must be selected
·This paper attempts to evaluate the mineralogical and chemical composition of sedimentary limestone mine waste alongside its mineral carbonation potential The limestone mine wastes were recovered as the waste materials after mining and crushing processes and were analyzed for mineral major and trace metal elements The major mineral composition
·In the mining process the shallow brine is easy to drain and the method of injecting fresh water to dissolve and extract brine resources is o˚en used to obtain more brine resources 12
