Epigenetics is the epi-information beyond the DNA sequence that can be inherited from
parents to offspring. From years of studies, people have found that histone modifications …

Coal deformation energy and gas expansion energy are the main power sources for coal
and gas outbursts (called outbursts for short). Although the combined effect hypothesis of the …

To evaluate the coal burst proneness more precisely, a new energy criterion namely the
residual elastic energy index was proposed. This study begins by performing the single …

Understanding the real physical and mechanical characteristics of deep rocks under in situ
geological conditions is fundamental for deep rock engineering. Rock mechanics that …

The top coal of extra-thick coal seams is susceptible to irreversible failure under cyclic
loading and stress rotation caused by longwall top coal mining. To ensure efficient mining …

As coal mining is extended to greater depths, it is found that the mechanical behavior of
deep coal differs from the mechanical behavior of shallow coal, resulting in a significant …

Coal brittleness is an important index for evaluating whether coal can be fractured
effectively. Coal with high brittleness can form a large complex network after fracturing, and …

Many underground engineering projects show that rockburst can occur in rocks at great
depth and high temperature, and temperature is a critical factor affecting the intensity of …

To investigate the effects of the pre-existing single crack angle on the mechanical behaviors
and energy storage characteristics of red sandstone, a series of uniaxial compression and …

A true triaxial test system was used to study the mechanical and damage characteristics of
coal under tiered cyclic maximum principal stress (σ 1), intermediate principal stress (σ 2) …
