Deformation Monitoring of Waste-Rock-Backfilled Mining Gob for Ground Control

Backfill mining is an effective option to mitigate ground subsidence, especially for mining under surface infrastructure, such as buildings, dams, rivers and railways. To evaluate its performance, continual long-term field monitoring of the deformation of backfilled gob is important to satisfy strict public scrutiny. Based on industrial Ethernet, a real-time monitoring system was established to...

Numerical modeling of tunneling induced ground deformation and its control

Tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. The predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. The commonly used Earth pressure balance (EPB) tunneling machines, uses the excavated soil in a pressu...

Floor Heave Mechanism of Gob-Side Entry Retaining with Fully-Mechanized Backfilling Mining

Serious floor heave in gob-side entry retaining (GER) with fully-mechanized gangue backfilling mining affects the transportation and ventilation safety of the mine. A theoretical mechanical model for the floor of gob-backfilled GER was established. The effects of the mechanical properties of floor strata, the granular compaction of backfilling area (BFA), the vertical support of roadside suppor...

Monitoring of mining induced surface deformation

The main objective of the project ”Monitoring of mining induced surface deformation” (ALOS-RA-94) is to evaluate multi-temporal PALSAR data for land surface deformation monitoring, using interferometric techniques. Differential interferometry using PALSAR data over several mining sites in Germany, Poland and Czech Republic, as well as over alpine landslides in Switzerland and Italy was used to ...
