In general, the production processes are more and more complex. This is the result of more and more sophisticated materials used, the pressure to save them as well as other production resources (ecological perspective), also the tendency to buy mobile products lighter and less power consuming than before. In previous years using highly specialized technology was very costly for the company. Nowadays,...
In current conditions, great attention is paid to the quality of parts, which is in many ways determined by finishing operations of mechanical treatment, with surface grinding being the most widespread. Grinding process efficiency, abrasive tool wear intensity, machined surface quality and other features of grinding process depend on properties of the environment, where the cutting process takes place...
The study presents the possibility of using geostatistical methods for monitoring groundwater quality. Poland is one of the largest copper producers in the world. However, the extraction and production of copper requires constant care for the natural environment. Reservoir Żelazny Most which is situated in South – Western Poland was designed to store flotation tailings out of nearby copper mines....
Energy security is one of the basic tasks carried out by individual countries. It is of great socio-economic and political importance and constitutes the basis for independent development of both economies and groups of countries. Access to adequate resources of affordable and environmentally neutral energy in the production process is the basis for sustainable energy development. Therefore, an important...
The supervision of OHS conditions (working conditions and the realization of work tasks) is one of the basic obligations of the employer. The number and variety of describing elements (and thus being subject to assessment) means that synthetic measures (measures that are one-dimensional images of complex phenomena) are more and more frequently applied to solve problems of that type. Although the methods...
At present, there are a large number of manufacturers operating on the market, which are engaged in the production and distribution of mechatronic and robotic toys. These toys range from the cheapest and simplest to sophisticated costly models for play education. Looking at the market offer, it can be stated that mechatronic toys are being produced, which are intended for children of several months...
The article summarizes the experience, skills of the students of technical subjects teaching methodologies using a number of software products. Solve specific assigned tasks described in this paper. Task is about the problems of automation and mechanization in the industry. That helps to improve the skills of praxis, through the design of construction and of controlling. Specifically it focuses on...
The article presents the use of video monitoring in a production company on the example of municipal thermal power plant. After analyzing the hazards and work inconvenience occurring in the analyzed enterprise, video surveillance zones have been designated with the division into the indoor and outdoor monitoring system. Video surveillance is provided for production, auxiliary and delivery processes...
This article is focused on enhancement of HW/SW device by cooperation with a smartphone interface. The device was a programmable Lego Mindstorms Education EV3 set in the form of a robot designed to solve the Rubik’s Cube. The aim of the research was to replace the built-in color sensor with a camera that would allow the cube scanning process to be accelerated. Two approaches were chosen to meet the...
Energy and climate issues are an essential part of the sustainable development process of the EU countries. They are also one of the primary objectives of international policy, as evidenced by their inclusion in Agenda 2030, adopted by the UN in 2015 among the Sustainable Development Goals. The implementation of these goals is also taking place in the EU countries. Although climate protection and...
The article is aimed on the possibility of fuzzy control of an experimental device that represents the simplified model of automobile steering booster. The main part of model consists of a graphical unit illustrating the control of speed and supporting torque. Based on the structure of fuzzy controller, various counts and configurations of fuzzy sets were defined, whereby the relevant results were...
The paper describes a solution of reverse engineering tasks using the equipment of the laboratory of the Technical University in Zvolen. The first task was linked to evaluation of a wear rate of the tool used to for mulching and elimination of unwanted wood or weed vegetation. The obtained data will be used as a base line for determination of the time interval for the tool replacement. We developed...
The growing requirements and needs of users as well as a strong emphasis on pro-ecological solutions cause an increasing interest in battery-powered electric mining machines. Internal combustion machines consume oxygen, generate noise, fumes and heat, which affects work in underground mines, and minimizing these factors is expensive. Battery solutions allow achieving the same operational parameters...
In hard coal mines with methane, there is often a need to apply demethylation in order to keep the methane concentration not exceeding 2% in the ventilation air. The basic demethylation method in longwall areas is through drainage boreholes made in the roof rocks of the coal bed, from top gate, in front of the longwall. The drainage boreholes are usually made in bundles, in a fan-shaped arrangement,...
In this work were analyzed factors and working conditions that leads to the wearing of junk mills tools that are a part of junk removal equipment used in drilling and workover of borehole. Such equipment is a part of oil and gas industry and work under condition of intense abrasive wearing with increased pressures and cyclic loads. Was established that traditional hardfacing materials based on the...
Throughout history, human beings have been affected by the ongoing events in their environment. While some of the events take place in the sphere they live on, some of them are in the way that events outside the earth affect the world. Necessary measures should be taken on time and in place so that people are not adversely affected or at least minimally affected by the aforementioned events. Geological...
The mining production process includes a number of sub-processes, the most important of which is mining the rock mass. In this process, increasingly modern mining machines are being used to replace human labor and to achieve high productivity. Full utilization of the potential of these machines is of great importance for the efficiency of individual stages and the whole process of mining production...
The mining production process is of particular importance for the area of Upper Silesia, as well as a very significant impact on the economy of the entire country. One of the most common and most dangerous threats to this process is the methane hazard. It is related to the presence of methane in coal seams, which under appropriate conditions is a flammable and explosive gas. Events related to the...
The paper presents the problem of quality assurance of the laser cutting process of wood and wood-like materials and the selection of optimal processing conditions with respect to the required evaluation criteria. An experiment conducted to identify processing difficulties and potential causes of defects is described. Samples of three materials: pine wood, hardwood plywood and mixed wood HDF with...
Cementing of casing string is a final operation before the next stage of well construction; it provides maximum operational life of the well. Cementing of casing string is carried out with the use of technology, based on squeezing of the whole volume of drilling mud by special grouting composition. The main purposes of cementing include isolation of water-bearing horizon, strengthening of borehole...
