Life of Mine (LOM) and Budgeting Process. agnicoeagle.com 5 • Record annual gold production of 1.10M oz, vs. guidance of 1.06M oz - 2013 total cash costs at $672/oz, below $690/oz gui dance This is why planning is more precise in the first year, a bit less in the second year and then less and less precise further into the future. the mining technologies currently in use on Federal leases and the potential for commer-cial mining technologies to extract Federal coal reserves from deep underground seams. The chapter discusses: three surface mining techniques that are used in the West: 1) area strip, 2) open pit, and 3) terrace pit; two methods of underground mining in The surface mining method of coal involves three ordered steps: overburden removal, coal seam removal, and reclamation. The first step in surface mining is to remove the rock over the coal seam called the overburden ( Fig. 2 ). Figure 2. Step 1 in the surface mining process, overburden removal (in cross section). 2.2 UML and Mine Planning System Models.. 12 Chapter 3 Systems Analysis and Modeling of a Conventional Open Pit Mine Planning System . 13 Figure 3-1: The open pit planning process.. 17 Figure 3-2: Select aspects of the mine business planning system.. 19 Figure 3-3: A block model constrained by mineralization and coloured by block • Identify and agree with client the process, people/skill, organization and system change required to realize the envisaged benefit • Determine key success factors. • Agree with client the improvement opportunities, high level solution themes, cost of changes and the annualized benefit. A good mine planning process makes effective use of the rapidly developing mine planning software that enable mineable shapes to be rapidly developed, schedules to be readily updated, and numerous options and scenarios to be evaluated relatively quickly. The increased integration between the mine design and scheduling software also readily Mine planning and design is an iterative and continuous process which starts at the conceptual stages of a new mining project, when the need for such a mining venture has been identified, and is only completed at the end of the mine's life when successful mine closure has been achieved. GUIDELINES FOR THE INTEGRATED PLANNING AND DESIGN OF UNDERGROUND COAL MINES. G. Fourie, D. V. Niekerk. Political Science. 2001. i i) Foreword Mine planning and design involves the compilation and integration of all relevant geological, geotechnical, mining, engineering and economic data into a single document to define and…. 2. The Life of Mine Plan (LOMP) is the formally approved long-term plan for the mine. It is selected after conducting an SOA, and is the plan identified as best delivering the corporate goal. It establishes the framework within which all other shorter-term plans are developed. The LOMP is reviewed and updated annually as part of the planning cycle according to jardine and evans (1989), mine production planning and scheduling includes six repeated tasks during life of mine: 1) extracting point data such as drillhole data and then 3-d geological modeling of deposit, 2) designing the mine pit limits, 3) building mining blocks and assigning reserve features to each block, 4) determining the … Keywords: open-pit mining, short-term planning, operations research 1 Introduction An open-pit mine consists of a set of pits, in which horizontal layers of material (benches) are extracted from the top down.
