Among all methods for investigating the complex phenomenon of the coal and gas outburst,
numerical modelling is the most comprehensive one that can consider all involved …

As an emerging waterless fracturing technology, supercritical carbon dioxide (SC-CO 2)
fracturing can reduce reservoir damage and dependence on water resources, and can also …

Shale reservoirs are extensively exploited using hydraulic fracturing, which forms multiple
cracks that connect with the existing natural fractures to create a continuous path for the gas …

A new poroelastic damage model is developed in the paper to describe the macroscopic
failure of rock materials due to microcrack nucleation and propagation based on a multiscale …

Microscale and nanoscale fractures induced by stress transfer can effectively improve pore
connectivity, which can provide significant benefits by improving well productivity in shale …

Reliable prediction of the shale fracturing process is a challenging problem in exploiting
deep shale oil and gas resources. Complex fracture networks need to be artificially created …

Computer aided optimization of cement-based materials proportion can accurately quantify
the accompanying microstructure evolution, material composition, and the mechanical …

Rock materials are typically heterogeneous. Traditional digital image processing (DIP)
technology and the grain-based model (GBM) method are difficult to apply to engineering …

The significant difference between the mechanical properties of soft rock and hard rock
results in the complexity of the failure mode of the anti-dip layered slope with soft and hard …

Coal seam gas drainage is not only the effective measure for gas outbursts control, but also
has the great significance for the use of gas energy and reduction of greenhouse-gas …
