Analysis And Synthesis

Stripping and mining operations at open-pit coal mines are performed mainly by heavy shovel-truck systems (STS). One of the main problems of the STS is a rather low level of its operation quality, an objective assessment of which is an important step in identifying the causes of low quality and effective ways to improve it. The purpose of assessing the STS operation quality is defined as a functional criterion. The next important step of the assessment is to choose the set of indicators that most characterize the STS operation quality. In this article we present the rationale, the general principles for the formation of quality indicators set, the sources and the main dependencies for its determination. For this purpose, modern methods of data collection and processing, analysis and synthesis are used. The ability to assess the STS operation quality is very important for identifying the main directions of improving its operational performance, reaching the optimization of the key performance indicators by the quality criterion, and, as a result, for the possible saving of material and technical resources in the open-pit mining of minerals.

Open-pit mining activities, including blasting, drilling, loading, and transport, often result in the direct emission of particulates and gases into the atmosphere. Occupational exposure to these pollutants is considered as the risk for health, especially the risk of developing respiratory diseases. An air quality monitoring system and spatial analysis are necessary to identify these potential hazards. In this study, we propose an air quality monitoring system that integrates gas and dust sensors into a small multi-rotor copter or unmanned aerial vehicle (UAV). Different spatial interpolation methods including trilinear interpolation, nearest neighbour, and natural neighbour applied to the monitoring data (CO, SO2, PM2.5, CO2) from our system to derive air concentration levels in the atmosphere of open-pit coal mines were also examined. The results show that the UAV based air quality monitoring system performed efficiently and safely in conditions of deep open-pit coal mines. In addition, for the estimation of the concentration level of gases and dust in unsampled points, trilinear interpolation performed with the most accurate result, followed by natural neighbor and nearest neighbor.

The problem of industrial injuries and occupational diseases of workers is relevant for all countries, including the Republic of Kazakhstan, where more than 200 people die every year and more than 2,000 are injured at workplaces due to hazardous and harmful production factors, including insufficient natural or artificial illumination of workplaces. The aim of the work is to study the level of illumination of workplaces at enterprises of the Republic of Kazakhstan and to establish the influence of this factor on the working conditions. The object of the study is workplaces and employees of one of the largest machine-building plants, where 60 employees were interviewed, and instrumental measurements of illumination levels were performed in two workshops. The questionnaire method and methods for assessing workplaces by the level of illumination were used. The analysis showed that the largest number of surveyed workers (58.4%) were not satisfied with the level of illumination; according to the instrumental measurements of illumination, 40.9% and 46.6% of workplaces were harmful and dangerous. Employees working under harmful conditions are entitled to a number of benefits and compensations. Thus, the creation of rational working conditions, including illumination of workplaces, helps to minimize injuries and occupational diseases and increase the efficiency and productivity of labor.

Today, up to two-thirds of the world’s minerals are mined in an open, more economical way. However, at the same time, billions of tons of overburden are extracted, which are piled in the dumps, where they are polluted, lose their value and, in addition, reduce the quality of the environment. The possibility of industrial use of various rocks of from quarry field characterizes the complexity of minerals extracted by surface mining. Currently, there are no clear criteria for determining the size of blocks when designing enterprises for open pit mining. In most cases, when designing open pit mines, a quarry field is conventionally divided into several blocks, which does not always ensure the optimal production capacity of the mining enterprise due to the uneven distribution of reserves in the block contours. Because of that, during the transition from one block to another, a decrease in the production capacity of the enterprise can be noted. To avoid productivity decreasing, the precise analysis of the block parameters must be performed.

Mining enterprises are widely introducing digital technologies and automation is one of such tools. Granularity monitoring, namely, the size determination of rock mass pieces is a common operational component of the processes that extract minerals by open-pit mining. The article proposes an approach that, in addition to the lump size distribution, makes it possible to estimate the lump form distribution as well. To investigate the effectiveness of monitoring the form of blasted rock mass lumps, the authors conducted experiments in four stages related to the rock condition. They include geological occurrence, explosive crushing, trommelling, and mill crushing. The relationship between these stages is presented and the change in the lumps fragment form is traced. The present article proposes an informational and analytical model of the processes at mining enterprises, extracting minerals by open-pit mining, as well as an algorithm for determining the lumps form and obtaining their distribution in the rock mass.

Abstract As a controllable active resource in China, coal mining is facing the transition from output to quality. Base d on the total mining production and average capacity, the current situation and level of coal mining at three scales of mine, city and province is analyzed , data support for the layout of sustainable mining development and the optimization of output is provided. The results show that China's coal is mainly mined by underground mining, accounting for 87%, with an average production capacity of 0.93 million tons. Open pit mining accounts for 13%, with an average production capacity of 5.73 million ton s. S o t he average production capacity of open pit and underground workers is 1.045 million tons, with 1,181 coal mines capacity lower than 0.3 million tons, accounting for 35% of the total coal mines, contributing only 4% to their output. They are distributed in about 48 cities in 6 provinces, seriously restricting the green coal mining. The coal industry should speed up the reduction of small coal mines in key provinces and cities, eliminate outdated product ion capacity in the central region, increase the speed and proportion of coal resources moving westward, and promote high quality development of coal mining.
