Under biaxial confinements, it is evident that the elastic moduli of the three types of rocks decrease, and the plasticity increases monotonously with the increase of the intermediate principal stress σ2. As σ2 increases, the biaxial compressive strength σbcs of rock increases initially and ...
And the mechanics mechanism of formation of three types of stope are analyzed.Jun-Ling HOUGuang-Xiang XIEYong-Zhi TANGJun-Bin LIMin-Hua WANGHOU Junling,XIE Guangxiang,TANG Yongzhi,et al. Three-dimensional mechanical characteristics of rocks surrounding the stope of thick unconsolidated layers and...
displacements corresponding to the peak shear stresses were found in the specimens consisting of three particle size ranges. The effect of different grain size compositions on the peak shear stress and its corresponding shear displacement of the rock mass was revealed. Specimens consisting of one grain...

Seismic section was comprehensively interpreted to discover three unconformity types including truncation-overlap unconformity, parallel-overlap unconformity and truncation-parallel unconformity. According to the log data analysis, the unconformities were divided into three parts vertically: rocks deposited ...
In the vertical direction, during the Chang 73 sedimentation period, the lake surface area and water depth reached their maxima, and S and Mh lithofacies developed, which were conducive to the formation of high-quality hydrocarbon source rocks for tight oil. During the Chang 72-Chang 71 ...
The gold orebodies occur as bed-like or lense, and mainly controlled by the faulted zone. The oxide ores are the main ore types, with few primary sulfide ores. It has a very sharp fluctuation in the amount of REE(∑REE=12.04×10-6-136.167×10-6)in the rocks of the gold deposit, ...
Three highly weathered inland saprolites developed over different parent rocks, namely basalt, granite and schist, were sampled and analyzed for their physicochemical properties. The profiles were located along new road cuts in Peninsular Malaysia with depth varying from 10 to 26 m deep. The soils ...
