Selection Mining Method

Mining method selection is one of the most critical and problematic activities of mining engineering. The ultimate goals of mining method selection are to maximize company profit, maximize recovery of the mineral resources and provide a safe environment for the miners by selecting the method with the least problems among the feasible alternatives.

Selection of mining method Context: The selection of a mining method for a given orebody can be a challenging assignment and may need to address personal bias for or against a particular method. The selection of the mining method may also need to occur prior to the completion of desired geotechnical or ore value determinations.

Mining method selection is the most important decision made in a mine project. The selection of a suitable mining method for an ore deposit requires the consideration of a numerous criteria, such as mining-geological factors, economic factors and miningtechnical factors.

Mining method selection is a decision that has a huge impact in every aspect of the mine. Each ore deposit has its own unique characteristics and for that the selection of the optimal mining method is a complex task. There are several factors to be considered in order to make a decision of the mining method to be adopted.

EduMine used to have a mining method selection tool available but they've since deleted it. According to their support it's gone and won't come back. I was wondering if anyone had a Java tool or similar that did mining method selection. Theirs was using the UNC Nicholas method. Thanks. 3 comments. share.

Feature Selection Scores. SQL Server Data Mining supports these popular and well-established methods for scoring attributes. The specific method used in any particular algorithm or data set depends on the data types, and the column usage.

These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is the most widely used method in North America.

Embedded methods are a catch-all group of techniques which perform feature selection as part of the model construction process. The exemplar of this approach is the LASSO method for constructing a linear model, which penalizes the regression coefficients with an L1 penalty, shrinking many of …

appropriate mining method is selected based on technical, economic, and environmentally accountable considerations. The first step in selecting the most appropriate mining method is to compare the economic efficiency of extraction of the deposit by surface and underground mining methods . This section reviews surface mining methods and ...

mining method, subsidence effect or gas leak effect, underground water status and so on, are neglected in both methods. This limitation also exists in the choices and alternatives of selection. In the scoring approach, ten mining methods are considered for selection. These methods in the order of increasing operating costs are: open pit mining ...

Mechanized mining technical process (MMTP) related to the control method of the shearer is a vital process in thin coal seam mining operations. An appropriate MMTP is closely related to safety, productivity, labour intensity, and efficiency. Hence, the evaluation of alternative MMTP is an important part of the mining design. Several parameters should be considered in MMTP evaluation, so the ...

Methods for Equipments Selection in Surface Mining; review A.Lashgari*, A.R.Yazdani, A.R.Sayadi Faculty of Engineering, Tarbiat Modares University, Tehran, Iran *E-mail address: [email protected] Abstract One of the principal costs in mine is related to purchase and application of equipment.

The selection of underground mining methods is primarily based on the geological/spatial setting of the deposit. Candidate methods can therefore be chosen and ranked based on estimated operational/capital costs, production rates, availability of labors and materials/equipments, and environmental considerations.

Feature selection is the process of reducing the number of input variables when developing a predictive model. It is desirable to reduce the number of input variables to both reduce the computational cost of modeling and, in some cases, to improve the performance of the model. Statistical-based feature selection methods involve evaluating the relationship between each input variable and the ...

This article primarily focuses on the initial selection of mobile equipment in hard rock mining operations. Introduction. The determination of the initial mobile equipment fleet is an important step in the overall underground mine design process, and is typically based on the production targets, mining methods, and stope dimensions.

The mining method selected is determined by the size, shape, orientation and type of orebody to be mined. The orebody can be narrow vein such as a gold mine in the Witwatersrand, the orebody can be massive similar to the Olympic Dam mine, South Australia, or Cadia-Ridgeway Mine, New South Wales.The width or size of the orebody is determined by the grade as well as the distribution of the ore.
