In 2008-2012 the Yakutniproalmaz Institute and the Institute of Mining developed scientific and methodological principles and design solutions for development of the Udachny and Botuobinsky deep open pit mines using steeply inclined ramps and the CAT-740B articulated dump trucks with the capacity of 39.5 tons. Research was conducted to determine the rational slope for articulated dump trucks in the Udachny open pit and to develop guidelines for safe operation of such dump trucks on steep inclines. The performed experiments demonstrated the ability of articulated dump trucks to safely haul rocks with loads that were close to the nominal capacity using ramps with the slope gradients up to 24% in various weather conditions. In spite of a sufficiently large number of studies on justification of parameters of developing deep open pit levels, many questions still require additional research. This is primarily explained by the limited experience of operating articulated dump trucks in Russian deep open pit mines. In this context, the issue of justifying the optimal slope gradients for all-wheel drive models of motor vehicles remains relevant. The authors of the article have analyzed the existing normative documents and methods to determine the rate of longitudinal slopes. As the result of the study, the physical criterion of the least action is proposed as the optimization criterion for the slope gradients of the in-pit roads when operating all-wheel drive dump trucks.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42026414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to eliminate the industrial conflict, the authors are proposing the following methodological principles for the operation of a mining facility: 1) industrial risk is one of the key criteria in making management decisions at the enterprise; 2) industrial risk management is an integral part of the industrial activity management; 3) informational basis of the industrial risk management is monitoring of the internal and external environment, labor and production processes, structural and functional basis of the labor safety system that enables identification of regular trends and development and implementation of preventive measures on this basis. Resolving the challenge of predicting and managing industrial risks within the framework of the labor safety system ensures transition from reducing the frequency of injuries to controlling the probability of their occurrence. For this purpose it is necessary to design a labor safety system with the specified parameters that would provide an acceptable level of industrial risks. The efficiency and designing of the system, as well as implementation of the proposed principles, directly depends on the personnel. Therefore, it is advisable to apply the competency building approach to personnel training. Application of the competency building approach helps to eliminate deficiencies related to performance of the functions; to accelerate decision-making and speed-up the response to new hazards when emergencies occur, to enhance the competency of personnel in a targeted way, to involve a large number of the mine personnel in the activities to ensure production safety. Formation and functioning of the labor safety assurance system based on the organizational and technical project will allow to integrate the procedures of industrial risk management into the production management system, thereby forming safe conditions, necessary and sufficient for effective execution of the production task.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45257171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most proven types of combined transport that provides high productivity is the truck-and-conveyor system. Therefore, this paper focuses on its adaptation to the future mining conditions (high dynamics of open pit mining development with creation of deep quarries, the need to reach open pit depths of up to 800–1200 m). The field of application of different types of transport is not static and changes along with the technical development of transport means, their introduction into mass production, and a change in the target group of mining and operating conditions. The article provides a systematization of open-pit transport applicable in modern conditions and shows the experience gained by the Institute of Mining of Ural branch of RAS in the in-pit crushing and conveying technology, mobile (semi-stationary) crushing and reloading plants and self-propelled crushing units. The results of calculations and technical and economic parameters of open-pit truck haulage and conveyor transport in a wide range of mining conditions are described. It is shown that an urgent research and engineering challenge is the development of technologies for the phased introduction of high-performance equipment for in-pit crushing and conveying transport to a great depth with a minimal additional extension of the open pit walls. At the same time, it is possible to use both steeply inclined and traditional belt conveyors, depending on the specific operating conditions. Conveyor transport is preferable for use at the main stage of the life cycle of deep quarries in terms of its efficiency and throughput, but its use is constrained by a number of factors considered in the paper.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44374548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The studies show that physiographic conditions, physical and mechanical properties of rocks, features of structural and tectonic structure of the rock mass can influence the unexpected character of the deformation phenomena. One of the important parameters that determines the development of catastrophic deformation processes is the geodynamic activity of the rock mass, which forms its stress state. The purpose of the research is to develop methodological approaches to identification of potentially hazardous areas in the rock mass. To do this, experimental studies were carried out in a mine where unexpected abnormal deformations took place, and the role of influencing factors was analyzed. Experiments were performed using geological, geophysical and geodetic methods. As the result of the study, it was established that unexpected emergency deformation processes develop in areas where the maximum number of complicating factors is concentrated. A rating evaluation of the area of surface development has been developed based on a combination of factors affecting the stability of the rock mass. The developed approaches make it possible to diagnose the rock mass and identify areas where geomechanical processes develop according to special parameters. Area zoning can be the basis for the development of automated monitoring system of rock mass deformations to prevent unexpected emergency events.","PeriodicalId":36119,"journal":{"name":"Gornaya Promyshlennost","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42769042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The consequences of extraction and primary processing of natural raw materials are the lack of effective control over the territories once the ore mining is completed. In order to develop effective methods to control the development of hazardous natural and man-made processes in the areas of inactive waste disposal facilities, it is necessary to analyze a sufficiently large set of data, including the condition of ground and surface waters, soils, flora, the efficiency of waste disposal facilities protection from direct or indirect impact on the natural environment. Research on modeling the processes of transfer and accumulation of pollutants includes a general assessment of the direction of man-made flows and selection of vegetation for phytoremediation of territories along the boundaries of the facilities as well as the direction of pollutant migration. The impact of mining facilities (dumps, tailings reservoirs) is directly correlated with the time of their existence, the toxicity and the rate of transformation of the components contained, the economic efficiency of their further utilization or conservation. Thus, the methodological approach to the rehabilitation of environmentally disadvantageous areas in places where mining and primary processing of resources is completed requires integration of several techniques and methods to assess the existing environmental situation. It also includes the speed and direction of its evolvement, and the economic assessment of damage to the natural environment.

It is acknowledged that the Mining Institute of the Ural Branch of the Russian Academy of Sciences is one of the priority scientific partners of the Yakutniproalmaz Institute. Over the many years of cooperation, a team of researchers from the Mining Institute of UB of RAS has studied the mining, geological and climatic conditions of mining operations in the permafrost zone. Innovative techniques and technologies for mining kimberlite ores in confined conditions of deep open pits as well as methods to assess and select the type of transport and dump truck models have been developed for the open pits and underground mines of AK ALROSA. Recommendations are provided on the safe operation of open-pit transport, including the one with robotic control. Studies have been carried out which were used as the basis to develop technological regulations for projects of reaching and developing reserves of the Udachnaya Tube. A calculation method was proposed and standards were developed for drilling and blasting operations in open pits of diamond mining enterprises of the Russian Federation located in the permafrost zone. The correlation of rock categories aaccording to blastability grade and the specific consumption of explosives, which we recommended, allows to establish rational limits for changing the parameters of drilling and blasting operations within the permafrost zone. Based on field studies, numerical values of the stress-and-strain state of the rock mass were defined during the construction of underground workings. The geomechanical conditions of underground mining of the Udachnaya Tube diamond deposit were justified for the conditions of transition from the open-pit mining operations to the underground ones, considering the stress-and-strain state and geodynamic activity of various sections of the rock massif.
