Strategic Planning - Mine Economics
▸ Strategic and business plans
▸ Energy Balances, Lignite production and striping ratios allocation to pits, detailed Budgets.
▸ Investments and feasibility studies for investments
▸ Expenses and Budget control
▸ Production and quality analysis and reporting
▸ Reassessment and annual revision of the lignite deposits reserves .
▸ Policymaking for mixtures of lignite (model connecting a mine with a power station) for the better functioning of the old power stations designed for depleted deposits.
▸ Monthly bulletin with the mines results, comprising:
∙ Results of production, compared with the past and the current program
∙ Costs (compared to past results and budget)
∙ Cost per mine
∙ P & L per mine
▸ Cost comparisons of continuous excavation systems with contractors operating trucks and shovels.
▸ System design and implementation of the contractors payment procedure based on distance and slope of transport road (work based on extensive computer simulations and data statistical processing).
▸ Establishment of electronic publishing and distribution of reports, presentations and results in a wide circle of recipients plus on-line“bookstore”.
▸ Compete redesign of cost centre codes for the new PPC ERP (based on SAP). The new codes are:
∙ Short (4 instead of 10 digits of the old system)
∙ Tree-like structure
∙ Alphanumeric, so machinery standard naming is used.
∙ Data use directly from warehouses instead of integrating information in code analysis.
Results:
∙ Simple and accurate cost center charging
∙ Ability to easily charge at the level of foreman
∙ Production costs two-dimensional (type of expenditure - work phase)
∙ Production machinery costing (cost per hour or per t or m³)
∙ Easy and plethora comparative costs between Mines
∙ Better budgeting
