Purpose. One of the most common problems mining companies face in developing open-cut deposits in complicated geological and climatic conditions is avalanches during the spring-winter work period. This phenomenon is accompanied by a rapid displacement of snow masses, which can lead to catastrophic consequences. In this regard, the article aims to d...

This article deals with the role and the place of risk-based thinking in today’s occupational safety and health (OSH) systems used by mining companies. A brief survey on modern challenges and pressures affecting companies, as well as on the structure of supply chains, is given. It is demonstrated that, despite all measures and actions that are bein...

The experience of the Arshanovsky coal pit in solving the problem of rational water disposal is presented. A wastewater and drainage water treatment system is proposed that can significantly reduce the content of suspended particles in clarified water discharged after settling and filtering – up to 1.5–5 mg/dm ³ , while the effect of water clarific...

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 analyzi...

Purpose. Rationale of priority areas in the field of hazard analysis at hazardous production facilities (HPF) and the develop­ment of a method that allows for spatial analysis of the risk of accidents at a high level of detail.methodology. The authors proposed a method for processing heterogeneous information in order to identify hazardous areasfor...

The article describes the main performances of the global coal industry, as well as key occupational safety and health indicators (OSH indicators) of the coal mining industry of the Russian Federation. The main goal of the article is to present the results of research of potential utilisation of the Elmeri observation method in order to evaluate sa...

The problem in question is relevant since the process of detonation and shockwaves collision and recompression of detonation products is a challenging task in terms of gas dynamics. The paper is aimed at addressing this problem that would enable to intentionally control the process of transferring energy of explosive to environment through choosing...

Modern trends in the Russian mining industry manifest themselves in a gradual increase in rock mass extraction volumes (in coal and ore mining industry), especially using open-cast mining. New mineral deposits continue to emerge, and the existing ones are being exploited, but the mining conditions are becoming more complicated and problematic, and...

Introduction: coal dust formed during mining is the main harmful factor of production and is able to participate in the formation of explosive mixtures. One of the effective methods of dust suppression is wetting the dust with water. Purpose of research is to determine the optimal parameters of dust suppression: water pressure and diameter of spray...

Rock destruction mechanism by explosions is sufficiently complex, since the destruction occurs in very short intervals at sufficiently high values of dynamic loads. Therefore, no common point of view on rock destruction by explosion has been developed up till now. This article discusses stressed state in medium at quasi-static stage of impact upon...

The current stage of the development of open pit mining is characterized by the increase in the depth of the quarry and the deterioration of mining and geological conditions of mining, which is inevitably accompanied by the release of large amounts of harmful gases and dust into the pit atmosphere. The presence of harmful impurities in the pit atmo...

The article analyzes the current state of industrial safety in the mining industry in Russia. The main reasons for today's accidents and injuries, as well as the specificities of modern systems of the industrial safety and labor protection control are presented. The results of the quantitative correlation-regression analysis of the traumatic factor...

The paper describes a mathematical model for the calculation of the parameters of dynamic loads on the wall of a blasthole (well) during the explosion of charges having various designs and different initiation modes. It presents the results of the calculations of a stress wave in the rock mass from the explosion of a blasting charge, and the gas-dy...
