Hace 4 días · In recent years, with the advancement of mining, water conservancy, and hydropower projects, the size of underground chambers has progressively increased, leading to a rise in complexity in the ...
Hace 2 días · Therefore, based on the inside rock vibrations have been recorded in our previous work (Gou et al. 2020), the wave propagation induced by underground explosives is first analyzed from inside rock to ground surface with considering the influences of geology and topography, then the ground motions induced by blasts at both ore blocks in an underground mine is recorded to analyze and predict PPV ...
Hace 4 días · The evolving patterns of shear mechanical characteristics and acoustic emission features of bolted rock joints were obtained, elucidating the influence of anchorage methods and revealing the shear failure mechanisms of joints under different anchorage lengths.
Hace 2 días · Rock mass strength identification in underground mines is crucial for designing safe excavation and mining operations. However, conventional methods using drill. ... International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (Vol. 13, No. 5
Hace 2 días · In rock mechanics, the presence of joints and fissures significantly affects the geological stability of a rock mass, especially in fractured rock mass, where they play a pivotal role. As the strength of rock is impacted by these discontinuities, the properties of jointed rock are particularly susceptible to the influence of ice within these joints during freezing temperatures ( Wang and Zhou ...
Hace 4 días · The loading system stiffness (LSS) of a rock mechanics testing machine is important in laboratory testing because it dictates whether the coal or rock failure process is stable or unstable. It is also critical to ejection kinetic energy after coal specimen failure.
Hace 2 días · A two-dimensional model of a loess underground cavern was developed using OptumG2. ... Rock Mechanics and Rock Engineering. 2023; 56: 6395-6410. Crossref; Scopus (1) Google Scholar, 46. Wu C. ... Precursor of microseismic energy and stress evolution induced by rockburst in coal mining: a case study from **ashijie, Shannxi, ...
