Abstract
Improvement of the management processes in mining companies is the major factor to improve their efficiency. Restructuring actions in the coal mining sector have changed the management structure and organisational systems in the mines and mining companies. Cost and responsibility centres have been identified, the departmental cost accounting, budgeting and controlling systems have been introduced, which opened new perspectives for development of mathematical models and methods to optimise the mine operations. A panel is perceived as a costly element of the spatial structure of mining activities, as it involves both the mining production and development works. A group of neighbouring panels operated by the same equipment unit might be defined as a panel field. Both longwall and exploitation panels are the points where costs are generated. Owing to the application of the departmental cost accounting, costs can be identified and accounted at points where they are generated. This offers new potential for research, particularly in analytical studies, creation of simulation models and calculation procedures supported by state-of-the-art computer techniques and the available numerical modelling packages. This study briefly outlines a certain field within the framework of methodology of designing rational parameters of longwall panels, starting from the analytical method in the deterministic approach, right through to the method supported by stochastic modelling. Application of the Monte Carlo method permits a simulation procedure such that during each iteration the random variables are drawn in such a manner as to fit the probability distribution pattern determined a priori. After a large number of random draws, we get a set of values of the adopted optimisation criterion. Statistical treatment of those values yields the expected value of the investigated criterion and the standard deviation, which is thought to be the best measure of risk.
