Mining shaft is the most important element of the underground mine. It determines the mine’s ability to work efficiently. Mining shaft is used for transporting employees, equipment and dirt or output. It also allows to perform fast rescue operation and ensures that employees in danger can be quickly evacuated. Last but not least, it allows ventilation and functioning underground. Mining shaft and especially the shaft tube are subject to influences, both geological and anthropogenic. In details: local geological structure (deposit tectonic structure), mass rock movements due to exploitation inside and outside of safety shaft pillar, underground watercourses and leakages of shaft or voids around the shaft (especially dangerous in case of salt exploitation). Ensuring shaft’s safe operation is the primary aim of measurements and observations performed in mining shafts. This involves not only determining the current technical condition of the mining shaft, but also determining causes of observed changes (Szczerbowski & Jóźwik 2002). In order to preserve the efficiency of every shafts several inventory works have been performed, described in details in Ordinance (Regulation of the Minister of Economy from 28th of June 2002) and its appendix (Appendix nr 4 to Regulation of the Minister of Economy from 28th of June 2002, Jaśkowski 2013). This paper presents an overview of measurement techniques which are in use in order to perform shift tube’s inventory, with particular emphasis on telemetric measurement methods. The author compares classical measurement methods with possibilities of telemetry in few cases: financial, time-consuming and measurable. As an example monitoring system designed for the “Wieliczka” Salt Mine has been described in details. The system based on extensometers (vertical and horizontal strain gauges) and inclinometers, joined on each level and sent to the data centre was used in 2014 and 2015 to monitor deformations on and between five levels (from 0 m to −36 m) during sealing and stiffening the shaft housing. Material, injected under considerable pressure (up to 30 MPa) to 92 boreholes located few meters from the shaft, could damage the reinforcement and cause critical failures of the shaft. In order to prevent such situations, mobile system for monitoring the condition of the structure of the shaft was mounted. Its indications allowed to define in the current time the value of deformation occurring in the shaft and, if necessary, to immediately modify the schedule and course of injection works. Analysis of the results shows a slight deformation of the shaft housing during the injection and demonstrates the advantages of the monitoring system as well as a novel method of high-pressure injections (Jaśkowski et al. 2016).

Artykuł dotyczy rozwiązań umożliwiających doskonalenie jakości usług transportowo-spedycyjnych poprzez funkcjonowanie systemu zarządzania jakością zgodnego z wymaganiami normy ISO 9001:2009 ze szczególnym uwzględnieniem pomiaru jakości realizowanych procesów. W artykule określono determinanty jakości w usługach transportowo-logistycznych oraz ich relację z procesami systemu zarządzania jakością. Na tej podstawie opracowano zestaw mierników stanowiących komplementarny zbiór pozwalający na ocenę skuteczności, efektywności, terminowości oraz jakości realizowanych działań. Zostały one przyporządkowane procesom podstawowym oraz pomocniczym. Przedstawione analizy i propozycje usprawnień w zakresie pomiaru procesów i stosowanych mierników mają swoje źródło w badaniach dotyczących pomiaru skuteczności systemów zarządzania jakością i narzędzi wykorzystywanych do tego celu. Badanie zostało przeprowadzone w przedsiębiorstwie PKS International CARGO S.A.

This article applies to solutions allowing improvement of the quality of transporting and shipping services with the help of the operation of the quality management system in accordance with the requirements of ISO 9001: 2009 with the particular emphasis on the measurement of the process quality. In the paper, the determinants of quality in transportation and logistics services as well as their relationship with the processes of the quality management system were identified. On this basis, a set of measurements, which make a complementary set, enabling the assessment of effectiveness, efficiency, timeliness and quality of the implemented measurements, were developed. The presented analysis and improvement suggestions, in the case of process measurement and used measurement tools, have their origins in studies concerning the effectiveness of quality management system measurements and tools used for this purpose. The research was conducted in the company PKS International CARGO SA.

W pracy przedstawiono model relacyjny, opracowany metodą analizy systemowej procesu zbioru i transportu jabłek w gospodarstwie sadowniczym. W wyniku odwzorowania izomorficznego model relacyjny tworzy para składająca się z 5 elementów i zbioru 10 relacji tworzących strukturę modelu, odzwierciedlającą najważniejsze procesy mające wpływ na czas zbioru i transportu jabłek. Sformułowany model relacyjny jest podstawą do opracowania modelu operacyjnego i jego logicznej weryfikacji.

The paper presents the relation model developed using the method involving system analysis of apple harvesting and transporting process in a fruit farm. As a result of isomorphic mapping, relation model is constituted by a pair consisting of 5 elements and a set of 10 relations forming model structure reflecting the most important processes affecting apple harvesting and transporting time. The formulated relation model provides the basis for operational model development and logical verification.
