nicholas 1981 mining method selection

Chapter

2020-6-11  Method Selection Process Ten basic mining methods, not including hydraulic or solution mining, should be con­ sidered in any selection process: 1) Open pit - a method where mining starts at the surface and waste is removed to uncover the ore; includes strip mining and quarrying. 2) Block caving - a method in which columns

Method Selection - A Numerical Approach

David E. Nicholas, Organization: The American Institute of Mining, Metallurgical, and Petroleum Engineers Pages: 15 Publication Date: Jan 1, 1981 Email to a Friend Abstract INTRODUCTION In this paper, a numerical process for selecting a mining method, with the emphasis on underground mass mining techniques, such as caving, induced caving, and ...

Mining method selection by multiple criteria decision ...

2009-8-26  In 1981 Nicholas suggested for the first time a numerical approach for mining method selection. The Nicholas methodology follows a numerical approach to rate different mining methods based on the rankings of specific input parameters. A numerical rating for each mining method is arrived at by summing these rankings. The higher the rating,

A new approach to mining method selection based on ...

The main purpose of this paper is to represent a solution to the problem of mining method selection (MMS) 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.
