The subject of this paper is the assessment of the influence of the construction and design elements on traffic safety at level crossings in undermined areas. The first part is dedicated to level crossings in the Czech Republic and accident rates at level crossings in the Moravian-Silesian Region. The following part describes the in situ experiment, which was conducted at selected crossings with different types of safety arrangements, intensity of traffic and traffic moments. Our results were compared with the res...

Introducing new technical solutions into practice is inseparably connected with a number of problems. In addition to obvious concerns about the quality, reliability and effectiveness of the solution, there are also social problems. They are related to distrust of employees regarding new solutions and is caused by a limited knowledge about the introduced product which is related to employees' concerns that such a product may disturb the existing state of balance. Therefore, in the case of introducing a new solution...

The Makmal gold deposit is located in the Republic of Kyrgyzstan. As a result of mining operations, under the bottom of the quarry, an open worked out space was formed with access to the surface above each chamber and overhanging rock consoles. This mining situation at the field caused the danger of sudden collapses of rock consoles and the walls of the chambers of the separating pillar. In this article, in order to justify the method of filling the voids and choosing the technology for the extraction of the pilla...

The paper deals with general aspects concerning the assessment of the roads technical condition based on the calculation of individual, combined and general performance indicators. Besides general aspects, the paper also presents a case study concerning the assessment of the technical condition on the national road section DN 18 Baia Mare ? Sighetu Marma?iei, Section E, km 52+000?km 62+000. The assessment of the technical condition on the analyzed road section was realized according to the COST 354 action of the E...

Restructuring of mining activity in Romania resulted in active implementation of reconstruction programs, upgrading and modernization of the mines in the Jiu Valley. These programs were aimed mainly at increasing labor productivity safely. Considering, along with requirements for ensuring a safe and healthy working environment, also the issues related to the drained methane valorization and to environmental protection restrictions it was imposed to rethink the so-called "global methane treatment" at the level of m...

The decisive factor in the process of under pressure networks inspection is determined by the correct choice of the control method in order to observe with great attention the possible faults caused by the physical wear and tear resulting from the long use. Emphasis is placed on safety conditions of under pressure equipment, which include mandatory minimum technical requirements for periodic checking of under pressure networks for pressurized, liquefied or dissolved gas. Defectoscopy is a set of procedures used to...

This paper compares the indicators of spatial development for the road network of Croatia towards chosen countries in Europe and on a county level in Croatia. It also shows the number of traffic accidents per counties and links it with indicators of spatial development. The paper presents the results of the research of spatial distribution of traffic accidents in Croatia by counties. An example of a hazardous site identification on the A6 motorway is provided by the accident data report. All the comparisons and an...
