Cyclic weak disturbance caused by blasting, drilling, earthquake and transport is an
important factor to deep rock projects failure. In order to study the influence of cyclic weak …

Mechanical excavation, blasting, adjacent rockburst and fracture slip that occur during
mining excavation impose dynamic loads on the rock mass, leading to further fracture of …

In large scale rock blasting operations, such as in mining, quarrying and tunneling, there are
usually a number of blast holes simultaneously, and the explosive charges are fired in …

An understanding of progressive time-dependent deformation is essential for determining
appropriate measures to ensure the long-term integrity of rock-masses surrounding …

Dynamic disturbance such as blasting may significantly affect the creep of rock.
Quantification of the influence of dynamic disturbance on the creep behavior of rock is a …

Rock dynamic fracture is a complex problem and has received considerable attention during
the last few decades. In this paper, tensile crack softening failure criterion is used to study …

Discontinuity‐controlled slopes constitute potentially fatal risks during exploitation activities
in open‐pit mines and severely threaten the safe mining of collieries. To investigate the …

We have established an experimental system to investigate waterjet impact capacity and
coal relaxation behaviors, with reference to hydraulic slotting. The results indicate that after …

During underground hard‐rock mining, the drilling and blasting method currently remains
the most economical excavation method, and the rock may experience a multistrain‐rate …

During underground mining, rock deformation may be time-dependent and is reflected in
rheological behavior. These changes may be also accelerated by dynamic disturbances …
