Metody monitoringu stability uhelných pilířů při dobývací metodě chodba-pilíř.

Abstract

The aim of this thesis is to describe methods of monitoring stability of coal pillars in mining method room and pillar. With this mining method is mining in Mining plant 2 locality North (former ČSM- North) in test regime. This thesis describes geological situation around this mining method. Then I deal with technical description of this mining method, geotechnical assessment for using separate roof bolt reinforcement and calculating stabile coal pillar. The most important part of this thesis are methods of monitoring stability coal pillars in mining method room and pillar. This chapter also contains controls of anchoring roof bolt reinforcement, measurement of scaling overburden and convergence of mine work. Results of monitoring are also presented in this chapter. The last chapter of this thesis deals with controls of mining works and roof bolt reinforcement.
