| Abstract: |
| Analysis is made on engineering geological condition and tectonic fissures distribution of targeted mine. And the developed joint fissures of the rock mass of critical area have been studied. Numerical simulation is used to study the stress changes and surrounding rock mass deformation law of fractured rock mass in the excavation and mining conditions. Taking advantage of non-pillar sublevel caving method, the influence of the surrounding rock stability of the fractured rock mass in different excavation phase has been researched. |
