“…The depth and degree of environmental hazard arising under the influence of these factors are due to a combination of environmental and mining conditions, which have specific features, and differ in coal basins, deposits and enterprises [6]. For this reason, the necessary set of measures to prevent, localize and eliminate negative environmental consequences should be developed before the start of technical works on mine elimination at the stage of pre-design work and design.…”

Mines have an impact on all components of the environment during and after coal mining. Process of restructuring coal industry and elimination of unprofitable mines changes anthropogenic impact on the environment. Structural and technological change in the geological massif is terminated, but other types of negative impact on the environment continue become more active. Elimination of coal mines is accompanied by the emergence of new phenomena and processes that were not in the period of operation of enterprises and that have a negative environmental impact. The degree of impact of the mine on the environment depends on many factorsgeological conditions, hydrogeological factors, development and quality of land allocated for mine workings. As a result of the combined effect of negative factors during mine elimination, sustainable increase in the area of territories with active development of flooding communal and industrial facilities, agricultural lands, communication facilities, transport highways are appeared. As a consequence processes of pollution of surface water and groundwater are activated, that combined with ground surface depression, accumulation of potential energy in flooded mine workings with the formation of hydro-geo-mechanical stresses and decrease of resistance of rock masses. Geochemical pollution of industrialurban and agricultural landscapes is observed almost everywhere. The paper lists types of environmental pollution that occurred after elimination of coal mines. Possible ways of solving environmental problems of mine elimination are considered.

“…Other researches (Bolobov et al 2012;Khoreshok et al 2012;Mamet'ev et al 2015;Kolesnichenko et al 2012) present test results of tangential rotary cutters operating on mining machines in mines in Kuzbass (Russia) and recommendations to improve their design. Advanced design of cutters with replaceable reinforcing cells, removable head, secured shank, etc., are offered in various scholarly proceedings (Bell, 2013;Bookhamer and Swope, 2014;Monyak et al, 2014;Parrott, 2014;Prokopenko et al, 2015bProkopenko et al, , 2016. Using ellipsoid cutter tips instead of conical ones is discussed by Khoreshok et al (2013).…”

The objective of this study was to find opportunities for metal waste recycling in the process of rock breaking in mines. A built-up cutter design for a combined cutter-loader and a recycling technique for a considerable portion of the deteriorated tool are suggested. Industrial tests have proven the possibility of a ten-fold increase in the use of cutters on mining machines for coal rock mass destruction. The proposed technique allows a four times reduction in metal consumption in the production and use of cutters and a reduction of the ultimate resulting waste by 80%. This advanced technique could be transferred extensively into such industries as open-cast mining, repair of motor-roads, construction and agriculture.
