... that utilizes PINN to identify these attributes and explores potential future applications of this framework. PROBLEM STATEMENT It is common that the location where field measurements of ground subsidence are taken and the boreholes used to gather information about subsurface geological layers do not align...

... 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...

... with slurry or spoils, and instant support of concrete segment lining, etc., which are mitigating the risk of subsidence. Numerous research has been conducted on the predictions of the settlement during design phases using analytical, empirical, and numerical methods. One of the most widely accepted analytic...

... 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...

... horizon and the time effect characteristics of microseismic events and pressure of support all verifies the effect that the subsidence of the one side overlying strata induces the rise of another side. The critical disturbance distance of the roof between two mines is 580-1900m. When the comovement effect...

... 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...

... to propagation of a caved zone toward the surface and formation of chimney subsidence. Chimney subsidence has numerous catastrophic consequences such as the adverse environmental impacts and damage to surface structures in vicinity of excavations. Due to the importance of subsidence in civil engineering...

... Abstract This contribution describes linkage of stress concentration at the face of tabular excavations, for example, longwall coal mine panels, at a meter scale to surface subsidence at a kilometer scale. Joints are considered according to orientation and spacing at an intermediate scale...

... Abstract One of the most concerns of room and pillar mining system is subsidence of the ground surface due to coal mining particularly in room and pillar mines. Subsidence of ground surface is a result of floor, pillar, or roof failure of the mine. At the same, due to many difficulties...

The results clearly showed that caving-induced surface deformations tend to be discontinuous and asymmetric due to large...

... Abstract When underground extractions occur beneath or in close proximity to valleys and other forms of irregular surface topographic features, the observed vertical subsidence at the base of the valley is less than that would be expected in flat terrain, while the valley sides are observed...

... ABSTRACT The ceasing of a two centuries intense French underground mining industry has let a stupendous number of disused mines exploited by the room and pillar method. By the end of the 1990s, a series of catastrophic ground collapse and subsidence phenomena in urbanized zones occurred...
