One of the most important issues in all stages of mining study is capital cost estimation. Determination of capital expenditure is a challenging issue for mine designers. In recent decade, quite a few number of studies have focused on proposing estimation models to predict mining capital cost. However, these efforts have not achieved to a predictor model with reliable range of error. Both of ov...

The conventional practice in open cut coal strip mining has been to blast the overburden or coal layers in separate blast events. This is done in order to maximise the benefits from throw blasting and also to limit coal losses. Each blast event usually has a particular design of hole diameters, burdens and spacings, explosive charges and blast timing in order to achieve the required blast outco...

Open source data mining software represents a new trend in data mining research, education and industrial applications, especially in small and medium enterprises (SMEs). With open source software an enterprise can easily initiate a data mining project using the most current technology. Often the software is available at no cost, allowing the enterprise to instead focus on ensuring their staff ...

There has been an emerging open source data mining software development in current times. In this work I carry out an empirical study to compare the performances of open source and commercial data mining software. The results clearly reveals that before and after data preprocessing of the two NASA datasets used in this work, commercial data mining software (MATLAB) outperforms open source data ...

Purpose. To identify development regularities related to a stress-strain state and stability of the open pit walls while mining steeply inclined iron-ore body at various stages considering deterministic stochastic components rock mass structural heterogeneity. Methodology. Numerical 3D simulation state; application strength reduction procedure determine safety factor, taking into account hetero...

ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. a number of algorithms such as floating or moving cone method, floating cone method ii and the corrected forms of this method, the korobov algorithm and the corrected form of this method, dynamic programming and the lerchs and grossmann algorithm based on grap...

As customers are the main asset of any organization, customer churn management is becoming a major task for organizations to retain their valuable customers. In the previous studies, the applicability and efficiency of hierarchical data mining techniques for churn prediction by combining two or more techniques have been proved to provide better performances than many single techniques over a nu...

Sustainability assessment has received numerous attentions in the mining industry. Mining sustainability includes the environmental, economic, and social dimensions, and a sustainable development is achieved when all these dimensions improve in a balanced manner. Therefore, to measure the sustainability score of a mine, we require an approach that evaluates all these three dimensions of mining ...

In order to mitigate the potential issue of abrupt water inrush in coal mining operations, elastic-plastic mechanics theory was employed simplify barrier floor strata into a thin rectangular plate. Subsequently, fluid-solid coupling damage model designed through utilization COMSOL Multiphysics software investigate coupled seepage and effects rock mass an equivalent continuous medium. The result...
