Purpose. To study the interaction of the sectional trains and the rail track with straight and curved sections and vertical and horizontal burrs affecting the stability, loading and safety of mining rail transport.

Methodology. We have designed the mathematical model of the movement of the sectional trains along the track with different burrs, deviations from normative requirements of operation and have determined indicators of burden, stability and safety of movement in difficult mining conditions.

Findings. We have carried out the theoretical studies of interaction of sectional trains and the rail track and have determined the indicators of burden, stability and safety of mine cars movement along the track which have horizontal and vertical burrs. The calculation model considers vehicles with loose and firm mounting of wheels and various rail track sections with the elasticdissipative rigid and knuckle joints.

Originality. We have determined the relations between the parameters of horizontal and vertical burrs in rails and the changes in burden, stability and movement safety of the mine cars at straight and curved sections of the rail track. We have determined extreme values of the indicators of interaction of components of transport sys-tem, have discovered the resonance phenomenon and de-termined critical speed for the safe mode of movement.

Practical implications. The obtained results of the research can be used to develop technical standards for construction, maintaining and repair of the mining rail transport.
