“…A preventive riskoriented approach [19] can be used as one of the solutions to the problem of collapses and landslide phenomena, which using expert assessment allows analyzing different sections of quarries and dumping sites, and, as a re sult, developing complexes of organizational and technologi cal measures to eliminate the potential danger. The data obtained from the construction of the fault tree showed that a comprehensive solution to the problem is need ed by engaging a riskbased approach and selecting measures to strengthen the ledges of the quarries and dump sites.…”

evAluAtIon of stABIlIty of sIDes of quArrIes AnD DuMps on the BAsIs of A rIsK-orIenteD ApproAch purpose. The current conditions for open pit mining lead to a number of problems that arise both for domestic and foreign enterprises of the mining complex. In this regard, the aim of the article is to assess the stability of the sides of quarries and dumps based on a riskbased approach. Methodology. The main research method is a method for analyzing the probability of certain risks, and the method is based on the use of a riskbased approach to assess the risk of collapse in quarries. This approach allows us to assess the stability of the quarry sides and dumps, as well as to select a set of measures to ensure the stability of the array. findings. The authors analyzed the existing shortcomings in the regulatory documents related to ensuring the sustainability of quarry sides and dumps. It was found that at the present stage they are not able to effectively ensure the development of internal local documents of enterprises in the field of the occurrence of damage associated with the collapse of rock masses. The data ob tained from the construction of the fault tree showed that a comprehensive solution to the problem is needed by attracting a risk based approach and selecting measures to strengthen the quarry sides and dumps. originality. For the first time, the authors applied a preventive riskbased approach to solve the problems with the stability of quarry sides and dumps in a real mountain facility. practical value. The results can be used to reduce the level of occupational injuries by reducing or eliminating emergencies as sociated with caving and landslide phenomena during the operation of an existing quarry.

“…The video recording complex consists of a laptop, from which data of video cameras are recorded, a network cable-twisted pair (12), with which the laptop was connected to a fiber optic path, which consisted of analog-to-digital converters (13) and fiber itself (14). The cameras (16,17) were connected to an analog-to-digital converter using network cables-twisted pairs (15).…”

“…Some CCCM, especially those obtained by carbonizing carbon fiber based on organic polymers, are characterized by an increase in strength with an increase in operating temperature up to 2700 ºC. At temperatures above 3000ºC, CCCM are efficient for a short time, since intense graphite sublimation begins (Kabanov et al, 2019;Kolotyrin et al, 2019;Radyuk et al, 2019).…”

Carbon-carbon composite materials are characterized by high heat resistance and thermostability for which they, in most of their physical and mechanical characteristics, can be attributed to the most promising materials. Approximately 81% of all carbon-carbon composite materials are used for the manufacture of brake rotors for aircraft, 18% – in space rocket technology, and only 1% – for all other areas of application. While the need for composites for rocket and space technology is constantly decreasing – the volume of production of brake disc rotors for aircraft is steadily growing, and therefore research on the properties of carbon-carbon composite materials (CCCM) under conditions of high-intensity thermal loading is extremely urgent at the moment. In this paper, we consider a method for introducing silicates and oxides hardening them with the addition of refractory, chemical elements into CCCM. Tests of tips from CCCM were carried out under conditions of high-intensity thermo-force loading. The objectives of the experiment were to obtain scalded forms of the tip model and to record the temperature on the surface during the action of a jet flowing out of the nozzle of the propulsion system (PS). The tip of the CCCM is blown by means of a propulsion system with a supersonic flow of a highly enthalpy oxygencontaining gas. The results of experimental studies were determined using video recording on the basis of which sequences of frames were obtained on the basis of which the burning forms were built. Using thermal imaging measurements, the temperature field on the model surface was determined during the entire time the supersonic gas flow was exposed to it.

“…The need to reduce harmful emissions in the air of working areas in open pits complimented by a significant excess of maximum permissible concentrations is described in the works of foreign scientists [31][32][33]. A lot of academic specialists have studied the risk-based approach to the exploitation of hazardous production facilities and have proposed the use of methods of spatial risk analysis [34] and the concept of "Vision Zero" [35]. The dependence of the safety of blasting operations and production efficiency and economic indicators of the products is unconditional [36].…”

The article presents comparison of the values of maximum permissible concentrations, revealed during the analysis of the national standards of Russia and Australia in the field of regulation of nitrogen oxides. The impact of poisoning of the workers of the quarry with nitrogen oxides after blasting operations are presented. A detailed review of studies of methods for reducing nitrogen oxide emissions is given. The way of decreasing emission of nitrogen oxides using highly active catalysts as a part of the profiled tamping is offered. Laboratory studies were carried out using a model explosive and pentaerythritol tetranitrate. The results obtained showed that zinc carbonate (ZnCO3) is the most effective. The reduction in the amount of nitrogen oxide emissions was 40% of that released during experiments without the addition of catalysts.
