... with a diameter of 7.37 m to join the airport station. The tunnel alignment passes under airport runway 06L/24R. To estimate the effects of TBM tunneling on surface subsidence under runway 06L/24R, a 2-D numerical analysis was conducted using the FLAC-2D code. Moreover, to monitor the surface and ground movements...

... and the stability problem of the dressing plant by surface subsidence in the area of the mine's protective pillar. There are many mining space areas due to the production activities of more than 10 years in the area, which deteriorates mining conditions and causes deformation failure of rock mass around the stopes...

... but also fresh air entrance in the voids. Gas can also migrate underground through overburden strata potentially affected by former underground mining activities (e.g. dewatering, subsidence, formation of cracks or fractures). Gas migration between mining voids and the surface is mostly driven by pressure...

... for economical production. Recently, it has been shown that rock mechanics may offer a huge cost saving potential during field abandonment, as the rock itself may restore the sealing capability of the cap rock given the right conditions. On a larger scale, reservoir compaction and surface subsidence also imply...

... Abstract In mine areas, ground movement such as surface subsidence and landslide is frequently caused by the influence of mining work in the past or at present. It is of great importance to assess the hazard of the disaster to reduce the consequent damage from it. This study aims to assess...
