Economic entities, along with increasing demands in politics as well as Polish and EU strategies in the field of the protection of environment, seek the minimalization of the pressure inflicted. The hard coal mining and processing industry, despite much success, is still producing considerable amount of solid waste. What is more, there are still many uncultivated mounds. The annual amount of waste produced is 31,5 mln of tons, and 568,8 mln of tons so far stored (as of the end of 2010). The waste from the current production is, in more than 90%, subjected to recycling and used mainly for the terrain leveling as well as engineering works, and those lingering on the mounds are being more often used. However, the generally accepted and standardized methods of such enterprise solvency are still lacking. It is connected with the fact that they require taking into consideration many aspects such as law, technical, economical, ecological and social ones. The cost-benefit analysis method, conducted from the point of view of a waste owner as well as a businessman wanting to cultivate waste and local authorities, on the terrain where the mould is located, has been suggested in the report. The proposed model solutions may be the basis for the analyses of similar type. Its application (use), along with the analyses results, has been presented on a particular example.

This paper presents an application of multiobjective nonlinear problems, to assist in planning the size of the demand for materials in the coal mine. To solve the problem proposed genetic algorithm VEGA (Vector Evaluated called Genetic Algorithm)in multicriteria optimization. For example, some materials used in the production process, and shows the application of the algorithm chosen by the decision maker a set of Pareto sub-optimal Solutions.

Głównym celem pracy jest przedstawienie możliwości uwzględniania nieporównywalności kryteriów w procedurze wielokryterialnego wspomagania decyzji z wykorzystaniem metody AHP. Praca dotyczy zastosowania metod wielokryterialnych do oceny projektów inwestycyjnych dotyczących wyrobiska wybierkowego w kopalni węgla kamiennego. Uwzględnienie nieporównywalności kryteriów związane jest z aspektami bezpieczeństwa pracy (występujących zagrożeń). Zagadnienia poruszone w pracy są konsekwencją analiz związanych z oceną w cyklu istnienia (życia) inwestycji oraz wykorzystania koncepcji dominacji ze względu na ryzyko do wspomagania decyzji przy nieporównywalności kryteriów.

The main aim of this paper is to present the possibilities to take into consideration non-comparability criteria in the procedure of multi-criteria decision support using AHP method. The work concerns the application of multi-criteria methods for the evaluation of investment projects associated with excavation in hard coal mine. The inclusion of non-comparability criteria is associated with the safety aspects of work (existing threats). The issues dealt with in the work are a consequence of the investment life cycle analysis evaluation and the use of the concept of risk dominance for the decision support.

The paper presents a facilitating procedure of the material planning requirements for a coal mining company. To determine the size of the materials are used the multicriteria model, the lexicographic goal programming and the maximin method. The main criteria in the site procedure are probabilities of covering the future demand for materials. The Application of the procedure is shown in the example of fixing a contract for mining wood, polyurethane adhesive, steel racks and smooth steel idlers.

An employment in the industry was seriously limited what caused the distinctive improvement in its economic effectiveness.

State aid in the hard coal mining industry reflects the long-term EU policy on balanced support for adaptation and restructuring processes in this sector. The greatest beneficiaries of the restructuring aid in 2002-2010 were mines in Germany, Spain, Poland, France and Romania. The reform of the coal sector in Poland to 2003 was characterized by poor effectiveness due to the recurring problem of rising debt, fear of political consequences and strong industry lobbies. Improvement of a technological innovation degree in Polish mines implies the need to provide increased funds for research and development, training employees and environmental protection. This will ensure more effective management of change, transforming coal mines in modern and profitable companies.
