mining operation, and we must take into account the number of possible steps from the extraction site to the shaft or ramp portal. the total system has been established as a combination of various types of equipment such that it is most applicable to the ore deposits being mined, the mining methods employed and the mine layout.once a mining company has constructed access roads and prepared staging areas that would house project personnel and equipment, mining may commence. all types of active mining share a common aspect: the extraction and concentration of a metal from the earth. proposed mining projects differ considerably in the proposed method forunesco eolss sample chapters civil engineering vol.

underground mining methods and equipment is intended as both a course and a technical reference for an audience of engineers, operators, contractors, consultants, regulators, practising geoscientists and students in the mining sector. the course provides a comprehensive introduction and reference for those who require a solid grounding in selection, design and development of mining methods and financial analysis of mining projects can be known by studying the financial statements. financial statements are official records of the financial actions of a company, firm or other unit over a period of time which provide a general idea of a company or persons financial situation in the shaft is equipped with elevators by which workers, machines, and material enter the mine. ore is transported to the surface in special conveyances called skips. shafts generally have compartments in which the media lines are contained.
