In response to the increasingly severe situation of main roadway shock in coal seams, with a focus on strong-bump seam roadways under an asymmetric goaf certain mine, theoretical analysis, numerical simulation, and engineering practices were employed. This study investigated factors influencing roof damage, changes stress, characteristics overlying strata movement. research unveiled mechanism prevention seams goaf. The results indicate that damage can be divided into two categories:...
There is a very thick water-bearing key strata above the coal seam in Binchang mining area. When scale large, it easily breaks and leads to rockburst with surge of water gushing panel. Adopting layout pattern small panel large pillar can improve stability main strata, but at present, research on under extra-thick still not perfect. Therefore, taking second third panels mine as engineering background, width are optimized by means theoretical analysis, field measurement, numerical simulation...
Understanding the dynamic mechanical properties and damage mechanisms of surrounding rock during blasting mining is crucial for preventing engineering accidents. In this study, triaxial uniaxial impact compression experiments were conducted on paste phyllite using a Split Hopkinson Pressure Bar (SHPB) device under various confining pressures strain rates. The effects pressure rate phyllite, including stress-strain behaviour, compressive strength, energy evolution characteristics,...
Impacts of argillisation surrounding rock due to water seepage on roadway bolting were investigated. First, the microstructure and mechanical properties argillaceous studied show weakening effect strength. Then contrastive tests made anchorage performance bolted areas permeability rock, with without seepage. Surrounding stability a typical Tailgate 721 in Qi'nan Mine was numerically simulated. Serious failure roof fall could be attributed chain reaction The key problem lies effective...
