Overlying strata movement law of continuous mining and continuous backfilling cemented-fill mining

Environmental Earth Sciences, 2021
Aiming at the problem of mining coal resources under the Yuxing Mine Ecological Park in Inner Mongolia, China, we adopted a continuous mining and continuous backfilling (CMCB) cemented-fill mining method; based on the systematic description of the mining and backfilling craft of the CMCB mining process, comprehensive use of theoretical analysis ...

An innovative strata movement model for predicting overlying strata deformations

Geotechnical and Geological Engineering, 2020
The overlying strata in mining could move, deform and break with the advancement of the underground mining operations and form the “three-vertical-zones” over the mined-out areas. In this paper, the influence function method based to predict the surface subsidence is innovatively introduced to establish the movement model of subsurface strata over ...
