(PDF) SURFACE MINING METHODS AND

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 practices. 1.1. Classification of Surface Mining Methods Extraction of mineral or energy resources by operations exclusively involving personnel working on the surface without provision of manned underground operations is referred to as surface mining.
