Strength and resilience are two critical attributes for making it through all of the ups and downs in life, but sometimes it can feel like the universe never stops testing our resolve. But this ...

we are pleased to start our 2025 wedge hole drilling program to assess the high-grade gold potential of the Campbell Shear below the Robertson Shaft. This approach is a very efficient and cost ...

These tend to cut the bolt by shear rather than stretch it ... in proportion to the change in tensile strength. For an example, going from grade 2 to grade 5 will allow a 60% increase in preload.

The dynamic response of rock mass is largely restricted by its joint surface. Previous studies have shown that the degradation of joint surface can not be ignored when calculating the shear strength ...

Artificially fractured feldspathic sandstone specimens were soaked in chemical solutions with pH values of 2, 7, and 12 for 3, 6, 9, 12, and 15 dry-wet cycles, followed by direct shear tests under ...
