    With the increasing need for energy, both in quantitative and qualitative terms increasingly demands that natural energy raw materials are used techno - economically and in environmentally optimal way. This should be especially popular in our country does not have sufficient and structurally favorable supplies of energy raw materials. In this paper the aim is to introduce and implement new unconventional method of coal exploitation in order to minimize the emission of harmful gases. Specifically it comes to underground gasification of coal which is still a new and developing technology

    Defining the sliding plane in micro plan on rocky massif using geoelectrical method

    The paper presents data from geoelectrical measurements of micro locations where there is a sliding rock mass. These studies have been conducted on location mountain Plackovica in the Eastern Macedonian zone. The observations were performed with an interval of two years. Method geoelectrical sounding was conducted. Measurements are performed multiple times on the same profile, in order to define the sliding plane, depending on the weather. From the data obtained from geoelectrical sounding it can be concluded that the specific electrical resistance of the rock masses decreases at a time of increased amount of rainfall. During dry periods of the year occur relatively high values of the specific resistance, especially in the surface layer. This phenomenon is normal to expect. The analysis of the specific electrical resistance in the investigated profile clearly indicates that the plane of the sliding rock masses characterized by reduced specific resistance in relation to the surrounding rock mass, especially in extremely wet weather. In these conditions comes to the intense activation of the process of sliding rock masses. The results obtained are consistent with the basic theoretical assumptions, i.e. the zone with increased amounts of water has a lower value of the intensity of the specific electrical resistance, although it is the same type of geological environment. The results of these studies indicate that geoelectrical methods can provide useful information when investigating the sliding plane in rock mass

    During the COVID-19 pandemic, the tourism industry was severely affected, and the travel patterns dramatically changed. Yet, the love for travel and leisure remained with a focus on the environment and rural areas. The paper presents new insights into the possibility of developing innovative tourism product based on the Earth’s natural electromagnetic waves with an extremely low frequency of 7.83[Hz]. It discusses the option for using the Schumann resonance for tourism purposes. The main objective of the research is to demonstrate the way some rural areas have the potential to apply the therapeutic benefit of the Earth’s magnetic field to tourists and visitors. Data measurements are collected in the village Lesnovo (North Macedonia) during 2019. It was found a presence of positive and harmonious energy vibrations, thus pointing to the possibility of creating a completely new dimension for rural areas. This may attract more visitors and boost the rural economy if raising the awareness that villages may offer much more than just an ordinary rural ambient. The paper adds to the scarce literature on Schumann’s effects on tourists along with its practical contribution for proposing new frontiers and innovative solutions for tourism development based on positive vibrations of the rural areas

    A prototype system for monitoring the deformation and stability of different type of critical constructions

    Get PDF
    In this paper, we present a system prototype for monitoring the deformation and stability of different types of critical constructions. This system can be applied in order to achieve a higher level of risk management and safer working conditions. The system can have a wide application, for example it can be used as a real-time system for detecting deformations of mining construction or other types of critical construction areas. The main component of this system contains a Laser distance measurement module and single-board computers (SBCs) Raspberry Pi. This system can be integrated as a module in an already pre-existing monitoring system or as a stand-alone system. Here the basic functionality of the system platform and what can be done to improve monitoring process will be presented

    Synchronization of overburden dumping in Bucim open pit mine in function of minimal costs

    Get PDF
    Overburden exploatation in open pit β€œBucim” is performed from 3 (three) ore bodies, with least 2 (two) excavating zone. Overburden dumping is in 3 dump: two external and one internal. The need for synchronization of work is imminent, given that it is the same transport machinery - 12 trucks. In this paper it was made an attempt for mathematical modeling of synchronization of transporting and overburden dumping in three dumps

    Geomechanical characteristics of the tailing dam "Topolnica"

    Get PDF
    The tailing dam "Topolnicaβ€œ is a storage type because it has a dual purpose, that is used for the disposal of tailings flotation in the space of a river bed and it accumulate fluid flow water from the river Topolnica which serving open pit mine with drinking water. First projected elevation was 610 m above sea level, it has long been exceeded and reached final height of 90 meters. In the last couple of years, when the elevation of the tailing dam arid approached to the final projected elevation, the open pit mine approached to develop technical documentation for the same elevation. It was made a additional project for elevation to the upstream slope for 20 meters, elevation 630 m. In 2006 it was made second additional project for elevation of the upstream slope for another 24 meters, elevation 654 m and a total height of the crown of 136 meters. With the implementation of a additional project for tailing dam it is numbered as a highest dams in Europe
