Systematic planning strategy for surface mining projects using computers - a case study
This paper describes the methodology of coal reserve analysis and subsequent effective mine planning techniques in order to avoid repetitive and ineffective tasks. A systematic approach to mine planning of a mining property in Western Virginia is discussed starting with reserve analysis and covering mine sequencing and scheduling for four different production and methods options. This is followed by cash flow analysis in order to choose the most desirable production and method option within the constraints of investment levels. After building the base data bank, the mining area was subdivided into small mining blocks and corresponding quantities of coal and overburden were obtained by interacting block coordinates with base data bank. Dragline and truck/loader systems were analyzed. A tabular approach for sequencing of the mining activities was used and thus mass balance and allocation was determined. This was followed by scheduling the project by introducing and using hauling subroutines and dragline performance information. Finally, cash flow analysis was performed for each production option and mining system. Graphs summarizing the results were produced showing unit price, payback period and internal rate of return. The paper also describes the mine planning strategy network and the sequencial relationship of various planning activities.
