On the basis of the massive amount of published literature and the long-term practice of our
research group in the field of prevention and control of rockburst, the research progress and …

Based on the review of a wide range of literature, this paper finds that:(1) the average
specific surface energy of various single crystals is only 0.8 J/m 2.(2) The average specific …

To comprehensively understand the differences in mechanical behavior of coal during the
mining process at different depths, cyclic triaxial loading and unloading (CTLU) experiments …

The main purpose of blasting operation is to produce desired and optimum mean size rock
fragments. Smaller or fine fragments cause the loss of ore during loading and transportation …

Triaxial compression tests were conducted on fine-to-medium–grained granite specimens,
with initial confining pressures of 10, 20, 40, and 60 MPa, under various loading and …

Theoretical and experimental studies have revealed that energy dissipation and release
play an important role in the deformation and failure of coal rocks. To determine the …

The Lazy Colliery in the Ostrava–Karvina Coalfield of the Upper Silesian Coal Basin
adopted modern longwall technology for an underground extraction of coal seam No. 504 …

Blasting is well-known as an effective method for fragmenting or moving rock in open-pit
mines. To evaluate the quality of blasting, the size of rock distribution is used as a critical …

Cut blasting with single free surface is the first step of the large-diameter long-hole (LDL)
mining method, which creates more relief space for subsequent blasting procedures. The …

Tongchuan sandstone in northwest China was taken as the research object to study the
micro-damage, macro-fracture characteristics and dynamic properties of rocks after freeze …
