The complex fracture network generated by CO 2 fracturing is conducive to coal seam gas
extraction. However, the conventional research carried out experiments on small-size …

Concrete made from rice husk ash (RHA) is stronger and more durable than normal
concrete. It can also help reduce greenhouse gas emissions. A feasible prediction model to …

The dynamic compressive strength (DCS) of frozen-thawed rock influences the stability of
rock mass in cold regions, especially when rock masses are possibly disturbed by dynamic …

In cold regions, the dynamic compressive strength (DCS) of rock damaged by freeze-thaw
weathering significantly influences the stability of rock engineering. Nevertheless, testing the …

Monitoring the carbon dioxide blast wave is an efficient method for determining the power of
carbon dioxide blasting. Due to the harsh measurement environment, noise is inevitably …

Considering the problems related to hydrofracturing, CO2 fracturing is a more effective way
to enhance the permeability of coal seams. Conventional research has focused on the …

In-situ stresses have a significant effect on blast results in deep rock mass. In this paper,
firstly, the effect of a prestress (similar to an in-situ stress) on the propagation of blasting …

Mortar bolts are an important part of the tunnel support structure, and tunnel blasting can
cause vibration hazards to the existing bolt support structure. According to the theory of …

To investigate the crack propagation mechanisms in low-permeability coal seams induced
by liquid CO2 phase change blasting under different blasting pressures, this research …

The inversion of seepage parameters is an important research topic in the safety evaluation
of earth-rock dams. Core earth-rock dam is a commonly used structural type in earth-rock …
