equipment selection for mining: with case studies. editors: burt, christina caccetta, louis free preview. helps readers design a long-term mining schedule that minimizes transportation and other costs demonstrates how to select the optimal fleet of trucks and loaders presents the truck and loader equipment selection problem in a the main purpose of this paper is to represent a solution to the problem of mining method selection in mining projects. To this aim, the well-known mms technique of nicholas has been modified so that in addition to eliminate its defects, it would be possible for mining engineers to easily assign their engineering judgments to unsteady and uncertain characteristics of mineral resources.may 01, 2016 the actual geotechnical information obtained from the mine between levels 330 ml and 400 ml was used as input data for ubc online method selection tool and the mining method selection tool the ubc mining method selection is a modification of the nicolas approach which places more emphasis on stoping method.
Attribute Subset Selection In Data Mining Geeksforgeeks
may 01, 2019 attribute subset selection is a technique which is used for data reduction in data mining process. data reduction reduces the size of data so that it can be used for analysis purposes more efficiently. need of attribute subset selection-the data set may have a large number of attributes. but some of those attributes can be irrelevant or redundant.underground mining method selection is one of the most important decisions that mining engineers have to make. choosing a suitable underground mining method to extract a mineral deposit is very important in terms of economics, safety and productivity of mining operations.feature selection is the second class of dimension reduction methods. they are used to reduce the number of predictors used by a model by selecting the best predictors among the original predictors.. this allows for smaller, faster scoring, and more meaningful generalized linear models feature selection techniques are often used in domains where there are many features and
