Rockburst Behaviors of Beishan Granite Subjected to Instantaneous Unloading

2013 Fourth International Conference on Digital Manufacturing & Automation, 2013
Deep geological disposal is an internationally accepted way to deal with high-level radioactive waste. A better understanding of mechanical characteristics of host rock is very important for the stability of underground excavation and its long-term safety during operation.

The influence of pH on diffusion of 75Se(IV) in Beishan granite

Journal of Radioanalytical and Nuclear Chemistry, 2018
The through-diffusion method and batch sorption experiments were used to explore the influence of pH on the diffusion behavior of 75Se(IV) in matrix Beishan granite (BsG). In the pH range of 2.0–8.5, the De values of 75Se(IV) in BsG decreased first and then increased with pH increasing, while the changing trend of Kd was nearly opposite.

The sorption interactions of humic acid onto Beishan granite

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2015
Abstract To explore the sorption phenomenon and mechanism between humic acid (HA) and Beishan granite (BsG), the influence of factors such as pH, contact time, ionic strength, temperature, HA concentration and solid-to-liquid ratio were investigated using the batch technique.

Migration study of iodine in Beishan granite by a column method

Journal of Radioanalytical and Nuclear Chemistry, 2013
The fate and migration behavior of radionuclides in environment are influenced by a series of physical and chemical processes such as advection, hydrodynamic dispersion (including mechanical dispersion and molecular diffusion), retention, chemical reaction and so on.

Migration of 75Se(IV) in crushed Beishan granite: Effects of the iron content

Journal of Hazardous Materials, 2017
The diffusion of selenite (labeled with 75Se) in compacted Beishan granite (BsG) was investigated using the in-diffusion capillary method at pH values from ∼2.0 to ∼11.0 under oxic and anoxic conditions. The results indicate that the apparent diffusion coefficient (Da) values of selenite in BsG always reached the minimum at approximately pH 5 ...

Comprehensive Evaluation of Soil Near Uranium Tailings, Beishan City, China

Bulletin of Environmental Contamination and Toxicology, 2018
To evaluate the impact of uranium tailings on soil composition and soil microbial, six soil samples at different distance from the uranium tailings (Beishan City, China) were collected for further analysis. Concentrations of radionuclides (238U and 232Th), heavy metals (Mn, Cd, Cr, Ni, Zn, and Pb) and organochlorine pesticide were determined by ICP-MS ...

Sorption of iodine on Beishan granite: effect of speciation and humic acid

Journal of Radioanalytical and Nuclear Chemistry, 2018
Sorption of iodine on Beishan granite was studied by batch method. Great difference exists in the sorption behaviors of I− and IO3−. Under acidic condition, the sorption of IO3− improves dramatically, and IO3− could partly convert to I−. However, the sorption of I− is close to zero at all studied pH.

Paleozoic multiple accretionary and collisional processes of the Beishan orogenic collage

American Journal of Science, 2010
The Beishan orogenic collage is located in the southernmost part of the Altaids, and connects the Southern Tien Shan suture to the west with the Solonker suture to the east. The orogen was previously regarded as early Paleozoic in age in contrast to the surrounding southern Altaid collages, which are Late Paleozoic or even Early Mesozoic.
