Methodology for Assessing the Stability of Drilling Rigs Based on Analytical Tests
Energies, 2021 Underground mining machines, such as wheel-tyre drilling rigs, are articulated and equipped with booms that project far beyond the undercarriage. Such a structure makes these machines prone to losing stability.

Model tests of road subsidence progress with underground cavities caused by cyclic dynamic load
Shuiwen dizhi gongcheng dizhi, 2021 Due to the cyclic dynamic load, the underground cavity will gradually develop into road subsidence. In view of this problem, this paper establishes model tests to simulate the whole developing process of road subsidence.
