Stress Measurement in Coal Seam Ahead of Longwall Face - Case Study

Popis výsledku v původním jazyce

Stress measurement and stress monitoring is an important task in mining geomechanics, because knowledge of the stress - strain state in a rock mass is the determining factor for the proper planning of roadway support and for the correct design of underground mining. This strategy is useful for ensuring mining safety, because increasing depth causes several issues, especially in areas with rockbur st hazard, when roadways are loaded by the pressure ahead of an advanced longwall or by the stresses inducedby destress blasting in overlying rock. Besides, mining is influenced by stress induced by previous excavation s , mining edges in the overburden or abandoned workings in the same seam. The paper presents experiments with Compact C onical - ended B orehole M onitoring (CC BM) probes, which were used for stress monitoring in the area of a high - capacity coal face at Karvina Mine at the Lazy site (Czech Republic). This longwall panel is influenced by all the factors mentioned above. Moni
