Opis:
Purpose: the main purpose of the article is to underline importance of updating knowledge by mine rescuers related to deteriorating geological conditions of mines, that can lead to accidents and events that result in serious disasters. Design/methodology/approach: theses presented in the article have been verified using: literature review, critical literature analysis, document research and comparative analysis. Findings: based on content of this article, mining rescue will be considered as the most important aspect of the entire occupational safety system. The main element in mine rescue is the lifeguard-specialist, who has unique and constantly improving qualifications and professional competences. Hence, the role and quality of mining rescue should be assessed not only in the scope of the tasks that it has to perform, but also perhaps even more importantly, in relation to new challenges that require the constant adaptation of mining rescue to fit dynamically changing organizational and technical conditions, both underground and on the surface of the mine. Originality/value: the article enriches knowledge and develops discussion in the area of mining rescue. Thanks to the knowledge presented in the article, it can be concluded that role and the rank of mining rescue lies not only in the dimension of tasks that it has to perform, but also importantly in the dimension of new challenges that determine the need to constantly adapt mining rescue to dynamically changing organizational and technical conditions, both underground and on the surface of mine sites.

Opis:
The method of unconventional solid rock loosening with undercutting anchors and the literature analysis of the problem are presented. The tests and test results of the rocks loosening process with a fixed undercutting anchor are described. The tests were carried out within the RODEST project, OPUS 10 competition No. 2015/19/B/ST10/02817, financed by the National Science Centre. Numerical modeling process as well as a series of laboratory and in situ tests were carried out. The test stand equipment and methodology for the in situ tests are presented. The tests were conducted in four mines, which allowed to obtain and determine the following characteristics: 1. loosening force as a function of anchoring depth (for a given type of rock), 2. the range of rock loosening in a function of anchoring depth (for a given type of rock), and 3. loosened rock volume as a function of anchoring depth (for a given type of rock). The in situ test results are compared with the concrete capacity design (CCD) model used for the calculation of anchor load capacity in concrete.

Opis:
Purpose: the main purpose of the article is to compare Polish and Chinese mine rescue services. It tries to bring closer the organization of mine rescue in Poland and in China and constitutes a development of the research work of the author's article entitled "Motivation to work in rescue services of young mining staff" (Hetmańczyk, 2017, pp. 19-24), indicating the main factors motivating young mining staff to work in the rescue services. Design/methodology/approach: theses presented in the article have been verified using: literature review, critical literature analysis, document research and comparative analysis. Findings: based on content of this article, it will be highlighted the need to seek new solutions to increase the efficiency of mine rescue. In the opinion of experts and practitioners in the area of security, the next "jump" may lead to the intensifying of preventive measures aimed at human beings, mainly focused on making changes in the consciousness of mining crews. In practice, this would mean including within the scope of preventive measures, those which have a major impact on the skills, motivation, and attitude to issues related to safe operation. Finally, the mine rescue system, through prevention and training, will strengthen safe mining practices. Originality/value: the article enriches knowledge and develops discussion in the area of mine rescue. Thanks to the knowledge presented in the article, it can be concluded that role and the rank of mining rescue lies not only in the dimension of tasks that it has to perform, but also importantly in the dimension of new challenges that determine the need to constantly adapt mining rescue to dynamically changing organizational and technical conditions, both underground and on the surface of mine sites.
