Patterns of Roof and Soil Convergence in Development Workings during Coal Seams Mining in Seismically Hazardous Areas of Kuzbass

Author details

Abstract

The work studies the patterns of roof and soil convergence in development workings during coal seams mining in seismically hazardous areas of Kuzbass. The formulation of the research problem, adaptation of methods for studying the processes of geomass deformation, analysis of the geodynamic and mining-technical situation and field studies were completed. Most of the Kuzbass mines work with coal seams at great depths. This is due to the risks of geomechanical, geodynamic and seismic events that have a negative impact on the safety of mining operations. One of the negative phenomena that has a significant impact on the safety of mining operations is the convergence of the roof and soil of preparatory mine workings. When mining formations of coal seams, areas of preparatory mine workings in the immediate vicinity of the goaf and located in zones of bearing pressure from the working faces are especially susceptible to intense deformation of rocks in the vicinity of mine workings. To study the convergence of the roof and soil convergence in development workings, full-scale measurements of vertical displacements in preparatory workings were carried out with their location in the zone of supporting rock pressure of the excavation site being mined in seismically hazardous areas of Kuzbass. Factors influencing the types of deformations and destruction of the host rocks and support elements of development workings were established. The dynamics of the energy of recorded seismic events was revealed at different rates of roof and soil convergence the within the excavation area. Consequences precursors of the rapid soil convergence in preparatory workings and measures to prevent negative phenomena were substantiated.
