Gas hydrates are a promising unconventional gas resource that can alleviate energy
tension. Unfortunately, borehole collapse is one fatal geomechanical issue restricting its …

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 …

The differential evolution (DE) algorithm was deployed to calibrate microparameters of the
DEM cohesive granular material. 4 macroparameters, namely, uniaxial compressive …

Compared to general anisotropic rocks, the contact zone composite rock composed of
strong and weak rocks has distinct characteristics in terms of structure and physical and …

A sound understanding of the geomechanical behavior of sandy reservoir containing
hydrate interlayer is crucial not only for safe exploitation of natural gas but also for assessing …

The heterogeneous distribution of hydrates in natural or synthetic hydrate-bearing
sediments (HBSs) has definitively proven its influences on hydrate dissociation and related …

The hydrate-bearing sediments (HBS) mechanical properties during hydrate dissociation
are important to the safe, efficient and sustainable exploitation of natural gas hydrates …

Frequency plays a pivotal role in determining the rock-breaking effect of self-excited
oscillating pulsed water jet. Experiments were conducted to investigate the relationship …

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 …

The limited efficiency of current supports has led to serious support system problems in
loess tunnel construction, which are mainly noted in arch distortion, shotcrete cracking …
