Łukasz CIEŚLIK, Piotr KULINOWSKI Abstract: This paper presents an analysis of selected designs of mechanical storage bins in relation to three primary functions: run-of-mine material retention, waste rock separation, and stabilization of material stream capacity. The study also systematizes technical solutions that ensure effective implementation of these functions, as well as those with limited applicability. The analysis has shown that the range of functions performed by a storage bin depends primarily on its design, loading and unloading methods, and the possibility of implementing a bypass function, rather than solely on its storage capacity. Keywords: mechanical storage bins, run-of-mine material retention, material stream stabilization, waste rock separation, underground transport |

Paweł KOCHAJ, Piotr KULINOWSKI Abstract: This article presents horizontal transportation of personnel in underground hard coal mines. It is indicated that the effectiveness of a transport system depends primarily on the degree of its integration with the mine infrastructure, the condition and characteristics of the transport route, traffic organization, and the level of technical and diagnostic supervision, rather than solely on the nominal parameters of the applied means of transport. Against the background of the solutions currently in use, the transport system of LW „Bogdanka” S.A. is characterized, based on the cooperation of rail-bound transport, suspended monorails, and belt conveyors. Particular attention is devoted to belt conveyors adapted for personnel transport, identifying the key determinants of their safe operation, including safety systems, operational parameter monitoring, legal requirements and approval procedures, as well as personnel training programs. The process of implementing personnel transport by belt conveyors at LW „Bogdanka” S.A. is presented. The commissioning of the first belt conveyor for personnel transport resulted in a reduction of crew travel time, an extension of effective working time in the longwall district, and a decreased use of diesel-powered rail transport. The results also indicate significant energy-related benefits and an improvement in the mine microclimate due to the reduction of heat emission, noise, and exhaust gases. In conclusion, it is emphasized that further development of personnel transport systems should focus on crew training, automation of supervision, implementation of predictive maintenance strategies, and integration with digital mine management systems.
