The article presents the SOK Research Project idea, course and final results. The project was oriented onto an implementation of exclusive bolting in one of the Polish underground coal mines, realized with use of a multifunction Bolter Miner. Until starting that project the Jastrzębska Spółka Węglowa S.A. (Jastrzębska Coal Company J.S.C.) has been using different types of other supports (steel arches as gallery / roadway supports). Previous trials of implementing exclusive bolting in the Polish coal mines in the nineties of the XX century were not successful due to different reasons. In the case of the SOK Research Project, after having conducted detailed geological and mining analyses, a part of the Seam 401 in the Budryk Mine was chosen for tests of exclusive bolting with use of JOY 12CM30 Bolter Miner in the gallery drilling operations. Due to previous experience, gained in the process of exclusive bolting in the Upper Silesian Coal Basin conditions, special attention was paid to bolting designing as well as an installation and monitoring. As the SOK Research Project was the first trial in Poland of gallery drilling using exclusive bolting and Bolter Miner, so it was difficult to predict exact costs and final efficiency results. For all the project participants, i.e. the mining crew, engineers, managers and researchers it was an on-job training in the scope of new technology. The SOK Research Project enabled to gain a lot of new experience and knowledge, leading to guidelines and conclusions which can be useful in the following exclusive bolting implementations with Bolter Miner technology.

W artykule przedstawiono tendencje rozwojowe lutowania miękkiego i twardego. Zaprezentowano perspektywiczne kierunki oraz obszary badawcze, które w ostatnich latach dynamicznie ewoluowały. Opisano charakterystyki materiałów, których lutowanie jest problematyczne. Udowodniono, że zastosowanie nowoczesnych technik oraz odpowiedni dobór materiałów dodatkowych, umożliwia ich jakościowe wytwarzanie. Przedstawiono rozwój systemów kontrolnych i stopnia zautomatyzowania stanowisk lutowniczych. Wskazano na dynamicznie rozwijające się metody lutowania, proponując przy tym alternatywne źródła ciepła.

Development trends of soldering and brazing technologies were presented in this paper. Perspective directions and research areas, which in recent years evolved rapidly, were introduced. Characteristics of materials, which soldering and brazing is problematic, were described and it was proven that use of modern techniques and appropriate selection of additive materials, enables their qualitative manufacture. Development of control systems and automation degree of soldering and brazing stations were presented. Rapidly developing methods of soldering and brazing were pointed out, giving an idea of alternative heat sources.
