interpretations. The writer must make it crystal clear to the reader which statements are observation and which are interpretation. In most circumstances, this is best accomplished by physically separating statements about new observations from statements about the meaning or sign 检疫您的观察从您的解释...
The degree of influence of these three factors is different, meaning the degree of sensitivity is not the same. The GRA method is used to study the factors that influence backfill strength. The relationship of each factor is analyzed, and the significance of each factor is revealed [46]. ...
However, it was found that a maximum tensile strength of about 1 MPa could be reliably determined, beyond which the samples did not fail in the expected fashion (meaning, a fracture surface normal to the tension loading axis and in the middle third specimen length) and so the test frame ...
In addition, with the increase in RS content, more AFt is generated, meaning more water is consumed, which indirectly increases the concentration of backfill slurry and significantly enhances the compressive strength of the backfill. When 10–30% RS is added, the compressive strength is 20% ...
There are many constitutive models of geomaterial proposed in literatures with various levels of complexity [14,15,16,17]. Until now, the Mohr–Coulomb elasto-plastic model is the most used one to simulate the mining backfill due to the simplicity and clear physical meaning of model parameters...
