“…The machine is also an assembly of individual machines connected together in such a way as to operate as a whole. The useful operation of machines is usually reflected in the processing of matter carried out in the working system of the machine (Biały, 2017). The way the machine operates and the machine control systems should be adapted to the operator.…”

“…The classification of factors affecting the use of nominal working time can be presented in the form of a flow chart (Figure 1). Taking into account the factors affecting the use of nominal working time of technical measures, it can be noted that this time is significantly influenced by ( Figure 1) (Biały, 2013;Biały, 2014;Biały, 2017):…”

This paper presents the problem of technical means failure, used both in longwall reinforcement and in the mining process. Longwall reinforcement – a concept related to launching a longwall mining excavation – is one of the most important elements in the process of hard coal seams exploitation. It consists in introducing all necessary machinery and equipment to the future longwall in order to enable the effective mining process. The efficiency of a longwall excavation as well as works related to the reinforcement of longwalls depends directly on properly selected machines and equipment of the longwall complex. In order to ensure greater effectiveness and efficiency, it is necessary to find the causes of the most frequent failures in these processes and effectively counteract them. These actions result in increased production availability of machines and equipment involved in the mining process. The increase of production availability is significantly influenced by the technical condition of technical means used both in longwall reinforcement and in the mining process, and their proper selection. This will ensure a largely failure-free and uninterrupted progress of works.

“…Currently, it is also necessary to take into account factors related to ecology or time. Problems at the operational level relate to the current organization of physical flows in order to minimize costs, ensure proper warehouse management, a more favorable means of transporting goods and achieving a high degree of readiness to fulfill orders (Biały, W. 2017). Purchases and supplies are responsible for the effective implementation of the flow of supply goods from their suppliers to customers.…”

Regardless of unit production, mass production – an excellent production plan is always expected to combine the exact amount of materials at the right time with production cells and employees. An accurate production plan saves money by reducing production costs and time. It helps to achieve the goal and generate the best production plan. The article addresses the problems of material resource organization in industrial, mining and processing enterprises, affecting production efficiency. Particularly the problems of planning and preparation of unit, serial and mass production in relation to specific products. Depending on the nature of material consumption (basic or auxiliary materials), different planning methods and techniques are used.

The article evaluates the failure rate of devices in the Mechanical Processing Plant using a traditional quality tool, the Pareto-Lorenzo diagram. A comparative analysis of failure rates was performed, recorded in repair, inspection and maintenance card. Then, changes were proposed in order to reduce failure rates and earlier detection of equipment malfunctions. In order to analyze the failure rate of grain washer equipment during thick coal preparation process, one quality management tools was used - the Pareto-Lorenzo diagram. In this case, it is important to assess the mechanical failure of devices, and demonstrating which devices generate most repairs. Based on materials made available by the mine, such as: Repair, inspection and maintenance cards, Device cards, DTR documentation. Quantitative and qualitative assessment the most frequently occurring mechanical failures during operation of devices in process enrichment of coarse sizes was carried out. An attempt was made to assess failure rate of devices on a grain washer. A comparative analysis of failure rates in 2015-2017 recorded in the repair, inspection and maintenance card was carried out. Then, changes were proposed to stand, in order reduce failure rates, and earlier detection equipment malfunctions.
