Every year worldwide coal mining companies seek to maintain the tendency of the mining machine fleet renewal. Various activities to maintain the service life of already operated mining equipment are implemented. In this regard, the urgent issue is the problem of efficient distribution of available machines in different geological conditions. The pr...
The statistical analysis of the stop-watch reading data on operation of tangential-rotary cutter bits in various geological and geotechnical conditions of coal deposits and in underground excavations has allowed classification of all types of cutter bit failures and placing them into two groups - design faults and operation faults, with the identif...
Based on the analysis of qualitative interaction between rocks and a rock-breaking tool, a new coefficient of the tool efficiency is proposed. This coefficient makes it possible to estimate the quality of the tool impact on broken rocks and to predict energy input of rock breaking and, consequently, productivity of mining machines in specific geote...

... This is the best option, except in weak geological conditions [14]. This method has been introduced globally and is implemented by many countries, such as Australia [18], India [19], Russia [20], and others [21,22]. In China, highwall mining was first described in the late 1990s, as pointed out in literature [23] that analyzes its potential application at the Antabao open-pit mine. ...

... Therefore, when purchasing new equipment, industrial companies are guided primarily by productivity and costs, rarely taking into account the environmental consequences of production modernization [11]. On the contrary, environmental import substitution, being part of a long-term strategy of sustainable development, should be aimed at the development of competitive industries focused on modern environmental standards and norms of resource consumption, and not at crowding out imported means of production [12]. ...
