Technologies for brown coal

In co-operation with universities and other research institutes Poltegor-Institute has drawn up some variants of possible scenarios of technological development and the exploitation of Poland's brown coal deposits.

Poltegor-Institute has played an important role in the establishment of modern Polish mining and power industry, which produces approximately 35 per cent of the country's cheapest electric power. Together with scientists and representatives of construction design companies as well as industry we have been the first in the world to develop both an integrated mining system involving excavators-conveyor belts-dumping machines (KTZ) and an automated control system, which is fundamental for the mining of brown coal, characterised by its competitiveness in comparison with other fuels.

These long-term projects, drawn up by Poltegor-Institute, concerning the technologies of the exploitation of brown coal deposits as well as of making them available, share the assumption that the production of electric power without CO2 emission, as well as of syngas, hydrogen or liquid fuel is possible.

Technological development scenarios, which are currently being drawn up, indicate large possibilities concerning brown coal resources. Such possibilities create conditions for the optimal choice of both development direction of making deposits available and of brown coal processing technology which makes use of the most recent achievements as far as the elimination of CO2 emission and the production of hydrogen - the fuel of the future - are concerned. Existing environmental conditionings, the indispensable development of technology and equipment, and, finally, the necessary improvement of the organizational level of production and management processes, have also been defined.

A few variants of development have been presented, concerning the choice of priorities as far as the availability of numerous indicated deposits is concerned. The variants consider also the technologies of converting brown coal into electric power. The project, which was carried out within the framework of the Foresight project and financed partly by the European Union and partly by research units themselves, with the financial assistance on the part of industry, has created the basis for the beginning of R&D, design and preparatory work; they will aim at long-term use of brown coal in a zero-waste, modern and economical technology which should play an important role in ensuring the country's power safety. n
