“…It was examined how the cutting tool efficiency depended on its setting angle [10,11]. The values of the angles ensuring free cutting, least cutting efforts and low energy consumption of fracture were found [12][13][14][15].…”

“…At the same time, the two-stage technology has clear advantages. It involves boring a pioneer hole of small diameter at the first stage with an auger screw rod in a direct course and then boring it at the second stage to the desired diameter in a reverse course [1][2][3][4][5][6][7][8].…”

The paper presents the results of studies of technical solutions proposed in Kuzbass State Technical University and implemented in auger drilling equipment, characterized by the presence of a cyclic feed of a boring machine on the face and the corresponding reverse of the work by hydraulic jacks. Operation of complexes, which design feature is to provide a common plane for the axis of the boring hole and vectors of axial forces of the auger feeding mechanisms, was researched. The stress state of the cyclic step-feeding mechanism’s functional elements by mathematical and software means of the finite element analysis is considered. The threshold values of the feed forces are determined from the point of view of ensuring the safety margin of welded joints used in the cyclic step-feeding mechanism’s structure, and from the point of operational reliability of the system as a whole. The obtained data allowed making recommendations for further improvement for the subsystem of the auger’s cyclic step-feeding mechanism.

“…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.…”

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.
