The stability of the sandwich composite structures formed by leaving coal pillar, roof rock
and floor rock (RCF) is of great significance to safe production of coal mines. The failure of …

Broken coal and rock (BCR) are an important component medium of the caving zone in the
goaf (or gob), as well as the main filling material of fault fracture zone and collapse column …

Water‐weakening effect is one of the most important factors inducing large deformation and
stability problems of shale strata in the Huangjiazhai Tunnel. The influence of water on shale …

The evolution of rock mass cracks is particularly important for the study of the rock mass
fracture instability and catastrophic mechanism of underground engineering. To investigate …

To explore the differences in mechanical and energy evolution characteristics of coal–rock
composite samples with different coal–rock height ratios, uniaxial compression tests of coal …

In order to explore the control effect of backfill mining on dynamic disasters under special
geological mining conditions of overlying thick magmatic rock (TMR), a three-dimensional …

The double-lane arrangement model is frequently used in underground coal mines because
it is beneficial to improve the mining efficiency of the working face. When the double-lane …

Slope deformation and failure are major challenges for hydropower station engineering.
Taking the left bank slope at the exit of the flood discharge tunnel of the Wudongde …

The compression deformation and particle breakage of gangue filling materials are
significantly affected by different particle size gradations. To study the mechanical behavior …

To analyse the impact of underground pressure on the variation in floor porosity and pore
water pressure distribution during the coal seam mining process, this paper uses closed and …
