Abstract

It is examined how convergence of roof and floor affects temporary roadways during extraction of coal measures in Kuzbass. The geological and geotechnical factors that can cause deformation in roadways are identified. Roadways are classified in terms of their location relative to a coal seam being mined and a coal seam being overmined in a coal series. The parameters and phases of deformation of rocks are analyzed as primary and secondary convergence of roof and floor rocks in temporary roadways. The primary convergence is observed in temporary roadways located in parallel to the mined-out void and driven in the bottom layer of a thick coal seam being overmined. The secondary convergence takes place in temporary roadways in the abutment pressure zone induced by the earlier mined-out extraction site.
