The factors that influence the selection of mining ways

These factors among others are what will influence the selection of a mining method and the overall plan for developing the orebody. Operating mines vary in size from small underground operations (some of these operations have only a few levels of production and may produce less than 100 tonnes of ore per day) to the large open pits (some of which move thousands of tonnes or ore and waste rock

The selection of the mining method is a complex task considering many technical, economic, human and historical factors. Analysing all these factors will assist in identifying the appropriate mining method that is technically feasible for the geometry of the orebody while also being a lowcost solution. Typically, more than one mining method could be appropriate for a single orebody, which may

Selection criteria for loading and hauling equipment

Selection of "ultra-class" mining trucks (≥ 290 -tonne payload) and suitable loading equipment is for specialist mining applications only. Where local operating environment and cost factors favourably supplement diminishing cost-benefits of truck scale, ultra-class trucks may be justified. Bigger is not always better – only where bigger can be shown to be better by reasons in addition

For practitioners, these rules for selection of the optimal pair of imputation method and classification algorithm may be developed for each situation depending on the characteristics of datasets and their missing values. This set of rules will be useful for users and developers of intelligent systems (recommenders, mobile applications, agent systems, etc.) to choose the imputation method and

THE DEVELOPMENT OF A NOVEL MODEL FOR MINING METHOD

Mining method selection (MMS) for mineral resources is one of the most signi cant steps in mining production man-agement. Due to the high costs involved and environmental problems, it is usually not possible to change the coal mining method after planning and starting the operation. In most cases, MMS can be considered as an irreversible process. Se-lecting a method for mining mainly

The selection and design process of the opencast pillar mining method was also influenced by the coal production rates and demand from the power station. Three seams are being mined; the no. 4 lower seam (S4L), no. 2 seam (S2), and the no. 1 seam (S1). The S4L and S1 are coal

Selection of Mining Method for Anomaly No 3 of Gol

Today, the selection of a mining method is a multi-criteria decisionmaking process, with many factors in this process connected to each other. These trends do not have a high degree of confidence. In this study the analytical hierarchy process was used to select the suitable mining method for anomaly No 3 of Gol-Gohar iron mine of Iran. The results of this study show that gathering all

Lung cancer risk prediction method based on feature

A method to predict the risk of lung cancer is proposed, based on two feature selection algorithms: Fisher and ReliefF, and BP Neural Networks. An appropriate quantity of risk factors was chosen for lung cancer risk prediction. The process featured two steps, firstly choosing the risk factors by combining two feature selection algorithms, then providing the predictive value by neural network

01/11/2011Features Selection. There are many factors that influence diabetes and the different aspects of the disease, and quite often it is unfeasible to take all in consideration. The feature selection method addresses this problem by selecting a few factors that are the most influential for each particular case. Four of the studies were conducted in order to identify a set of the best predictors from

models), starts by using a two-step selection method to select "control" fac-tors from h t, and then estimates the SDF loading of g t from cross-sectional regressions that include g t and the selected factors from h t. As the name implies, the "double selection" of factors from h t occurs in two stages.

INTRODUCTION TO MINING

INTRODUCTION TO MINING 1.1 MINING'S CONTRIBUTION TO CIVILIZATION Mining may well have been the second of humankind's earliest endeavors— granted that agriculture was the first. The two industries ranked together as the primary or basic industries of early civilization. Little has changed in the importance of these industries since the beginning of civilization. If we consider fishing
