Opis:
Ensuring the stability of mining excavations is a crucial aspect of underground mining. For this purpose, appropriate shapes, dimensions, and support of workings are designed for the given mining and geological conditions. However, for the proper assessment of the adequacy of the used technical solutions, and the calibration of the models used in the support design, it is necessary to monitor the behavior of the excavation. It should apply to the rock mass and the support. The paper presents the automatic system designed for underground workings monitoring, and the example of its use in the heading. Electronic devices that measure the rock mass movements in the roof, the load on the standing support, and on bolts, the stress in the rock mass, are connected to the datalogger and can collect data for a long of time without any maintenance, also in hard-to-reach places. This feature enables the system to be widely used, in particular, in excavations in the vicinity of exploitation, goafs, or in the area of a liquidated exploitation field.

The article is a report of studies on the relationship between social support and the effectiveness of treatment for diabetes in youth. The aim of this study was to answer the question whether between patients with different treatment outcome differences in perceived social support. The study were 100-strong group of diabetics aged 16–18 years (50 girls and 50 boys), which has been assigned to groups of varying effectiveness of diabetes management. Adopted two criteria for allocation of subjects into groups: 1) the level of self-control of diabetes measured by the scale of „Treatment of Diabetes”(LC), 2) the degree of metabolic control measured by HbA1c. To measure the social support Sarason’s Social Support Questionnaire was used. Analysis of test results does not reveal significant differences in social support among patients with high and low self-control. In patients with varying degrees of metabolic control of diabetes patients with poor treatment outcome perceive less social support network (p < 0.05), but they are more satisfied with it (p < 0.01) than patients with good control of diabetes. In addition, the length of morbidity of diabetes is moderately, negatively correlated with the network of support and the degree of satisfaction with the aid received.

Opis:
The subject of thin seam exploitation is a complex problem; in reality, it involves several problems such as technical, ergonomic, and economic barriers. They refer mainly to combined longwalls – where a human presence is required at the site; the most important problem is the issue of the limited workspace in longwall roadways. This generates engineering and organizational problems, especially during the launching and removal of the longwall roadways. Having considered the above-mentioned, the Department of Mining, Dressing, and Transport Machines at AGH in Krakow has begun research whose main objective is to develop and test a new structure for a powered support for thin seams. In this paper, virtual models of the new hydraulic roof support and a conception of the structure of a control system were presented as well as the test results of the new construction hydraulic roof support. Research in this field was conducted for the project entitled “Studies of the Development of an Innovative Hydraulic Roof Support for Low Seams”. The project is funded by the National Center of Research and Development (NCBiR).

Opis:
A multi-criteria model for determining the order size for materials used in production has been presented. It was assumed that the consumption rate of each material is a random variable with a known probability distribution. Using such a model, in which the purchase cost of materials ordered is limited, three criteria were considered: order size, probability of a lack of materials in the production process, and deviations in the order size from the consumption rate in past periods. Based on an example, it has been shown how to use the model to determine the order sizes for polyurethane adhesive and wood in a hard-coal mine.

Opis:
All definitions for integrated control agree that maximum emphasis should be put on prevention by using resistant cultivars and cultural measures. Moreover, the use of plant protection products should be limited to the essential minimum using Decision Support Systems (DSSs) that integrate and organise all relevant information. Computer-based DSSs that require weather information and regular late blight scouting inputs have been developed and validated in a number of European countries. In the frame of the EU concerted action “European network for development of an integrated control strategy of potato late blight (EU.NET.ICP)” several DSSs were validated in 1999-2001. The overall conclusion was that in most cases the use of DSSs combined a good disease control with a reduction of fungicide input. The DSSs can be used as a PC-version but more and more, parts of information are delivered to users by phone, fax, e-mail, SMS and websites on the Internet. An important task for the near future is to update the DSSs with information on the epidemiology of the new aggressive population of Phytophthora infestans. Issues such as (1) the influence of temperature and relative humidity on the infection process, (2) the role of primary inoculum sources (seed, oospores, volunteers, dumps), (3) the role of secondary inoculum sources (distance, severity), (4) control of early blight and (5) resistance ratings for foliar and tuber blight have to be addressed in order to be able to formulate a robust control strategy that effectively controls late (and early) blight with a minimum input of fungicides.

Opis:
Voltage source converter-based multi-terminal high-voltage direct current (VSCMTDC) transmission system can realize a multi-point power supply, multi-drop power receiving, and mutual coordination between the converter stations to ensure the reliability of the transmission. Based on the PSCAD/EMTDC platform, a five-terminal DC transmission system model is established. According to the fast power regulation capability and overload capacity of theVSC-MTDC power transmission system, an analysis of additional emergency power support for a transmission system under large disturbance conditions was carried out. A new control strategy for emergency power support that introduces its basic principle is proposed in this paper. It uses the short-term overload capability of the DC system. By changing the power reserve of the converter station and the electrical distance between the converter stations, the influence of the power reserve and the electrical distance on the emergency power supply guarantee is analyzed the stability of the system is improved, thereby improving the sudden change of power caused by voltage fluctuations, and the feasibility of the control module is verified by PSCAD simulation. The simulation results show that when the system power supply suddenly changes, the converter stations at a short distance and large power reserve has a better effect on emergency power supply protection. A comparative study of the active power support of a single converter station and multiple converter stations is carried out. The research results show that the use of emergency power support in the DC transmission system has a good effect on maintaining the stability of the inter-connection system and the reliability of the power supply.

The article presents the methodology and results of tests of a prototype controller designed for the electrohydraulic control system of a powered roof support. This controller is the basic part of the developed, innovative control system. The tests were carried out on a custom-designed testing station, equipped with one section of a roof support. The aim of the research was to check the functionality and speed of the controller's response while working with the actual support section. The tested controller and the control system has a modular structure, which greatly facilitates its operation and use. Measurements of control functions were carried out on the controller connected to the electrohydraulic control block. The research mainly focused on determining the period starting from the moment of providing the signal to the moment of switching on the basic functions performed by the support section. The obtained results confirm the assumptions made. The controller's operation is very stable, and its response times are very short. It can therefore be assumed that the tested controller is correctly designed and constructed. This creates great possibilities for its practical application in the built-in system for controlling the roof support. This may be particularly important in the case of high-efficiency longwall complexes, for which wireless control of the support is planned to be used. The presented research methodology and obtained results should therefore be an important source of information in the field of testing controllers for powered roof supports.

Mining machines suitable for hard coal mining, due to the specifics of this industry must be characterized by very high technical parameters. In particular, it concerns their durability, reliability and availability. Currently used machines approved for operation in underground conditions meet such requirements. Nevertheless, during their operation it is reasonable to conduct supervision and control of work parameters. This applies to both machine manufacturers and users, which is especially important in the event of a failure. Mine employees should be able control of the entire operation process. This control can be effective thanks to a visualization system developed to monitor the working parameters of mining systems. The paper discusses the innovative system and presents the results of efficiency tests. They concerned the visualization of the operation of a powered roof support. The obtained results indicate that the assumed goal of the system has been achieved. The system is built on elements of industrial automation, which guarantees the reliability of the indicated values. Its graphic layout and selection of the presented parameters are also approved. It should also be emphasized that the system can work with currently operating systems and is easy to expand. According to the Authors, the system should find a wide application in practice.

A decision support system for designing effective noise hazard prevention (NHP) strategies is proposed. NHP consists of four modules: (a) database, (b) input, (c) algorithms, and (d) solution. The user can choose among single-, two-, and three-approach solution procedures. Heuristic and genetic algorithms are used to determine appropriate noise controls (NCs). From the given noise condition and NC budget, NHP recommends a minimum-cost NHP strategy that prevents any worker’s daily noise exposure from exceeding the permissible level. If the budget is insufficient, NHP is able to search for a feasible noise hazard strategy that requires a minimum NC budget.

The article describes how social disorganization is conditioned by such phenomena as social cohesion, informal social control and the ability of the community to control criminal behaviour. The article reviews the research indicating the harmful practice of creating social housing zones in large cities, in which young people with low cultural and economic capital are concentrated. This tendency is not matched by the regularity of high cohesion and high informal social control in ethnically distinct neighbourhoods, but uniform in this respect, which has been revealed in the research. The response of educators, social workers, and youth activists to disadvantage areas is the organization of street work centers and group work centers in these places.
