Opis:
Mine transportation of materials in underground mine workings is realized by mine underground railways as well as by suspended monorails or floor-mounted railway. Transportation is realized on tracks placed on the floor of working or on rails suspended to roadway support. Each transport operation must be preceded by a transport design project, made in accordance with obligatory legislation. A part of the project are traction calculations. Their implementation in a computer program allows for minimization of the possibility of errors during the configuration of suspended queues and conducting traction calculations, which consequently leads to improve the level of safety. The article discusses the modular Safe Trans Design system, supporting the design of auxiliary mine transportation. The system has been implemented in the mines of JSW S.A. The assumptions and structure of the system as well as algorithms of operation of the ‘configurator of transportation sets’ and ‘assessment and reporting module’ are presented. The method of creating an auxiliary mine transportation system project is presented. Safe Trans Design system is used in planning, organizational and training activities implemented as part of transport safety management in mining plants. Developed methods can be easily adapted to other legislations of hard coal producers’ countries, where suspended monorails are used in underground auxiliary mining transportation systems.

Opis:
Despite the fact that suspended monorails have been used in the mining industry for over 50 years it is necessary to continue research on the possibilities of increasing the unit mass of the transported load or the speed of people transport. The first step is to establish the exact dynamic load of suspended route’ elements and compare this value with easy to calculation static load. The objective of the research was to determine the influence of speed and direction of travel on maximum load force applied to the sling of the route in mining excavation. The research results indicated that the speed of 2 ms−1 does not significantly influence the load on the sling. Theoretical hypothesis, stating that the estimation of the force value in the sling ought to be performed using projecting on a surface perpendicular to the route was confirmed. It was also proven that in order to characterize the geometry of the sling as well as a precise analysis of its load it is necessary to employ the length and the angle of the chain in relation to the above mentioned surface. Upon employing statistical analysis of the test results, the maximum dynamic effect of the locomotive passing was determined to be 20.1 ± 2.5% of the value of the calculated static load for all slings, projected onto a plane perpendicular to the route. For a single sling, mounted on a test route section inclined at an angle of about 10°, the increase in force due to the passage of the locomotive was up to 21.0% of the static load for this sling.

Opis:
This article presents the results of experimental studies aimed at identifying the forces and acceleration during the riding and braking action of a suspended monorail. The tests were conducted under in situ conditions, in a dip-heading “B” ZG SILTECH in Zabrze. The paper also discusses a test stand, a metering system, and presents the impact of changes in speed on forces in slings of the suspended route. The measurements of selected parameters were performed for three variants: the route, the emergency haulage braking and the braking trolley set braking. The results include waveforms of forces in route slings, and acceleration values acting on the operator and transported load.
