Study and rationale of tectonic fault crossing technology parameters by the mine face of a preparatory mine excavation

zones with geological disturbances, using systems for securing and
stabilising near-contour unstable rocks to reduce their disintegration
along the production workings. The study included stand and mine
tests of fast-hardening anchoring systems, assessment of their bearing
capacity, and mathematical modelling of the stratification of the
massif weakened at the contacts, with the representation of
geological disturbance around the rock layers and coal seam
interlayers, to determine the stresses on the workings support and
assess the condition of unstable supported spans in the disturbance
zones. The study has shown the effectiveness of testing the
technology of supporting workings, covering different degrees of
rock mass disturbance, which allows for the successful passage of
workings through disturbed areas using a combined support scheme.
The developed technological scheme for mining operations, based on
analytical modelling and the use of advanced support technology,
addressed the geomechanics of disintegration processes in rocks and
the impact of mining operating parameters on the moving front of
cleaning operations in underground deposits. This study confirmed a
significant reduction in risks when mining through disturbed areas of
the rock mass due to the use of the developed technological support
scheme. In addition, analytical modelling determined the optimal
parameters of underground mining operations to improve the stability
of mine workings when sinking through disturbed areas.
