Drill and blast method has been widely used as an effective excavation for underground rock caverns or tunnels. To achieve a good design, understanding on the dynamic response fragmentation process is important. In this paper, numerical simulations are performed typical parallel hole cut blasting based discontinuous deformation analysis (DDA). The loading obtained from explicit FEM code LS-DYNA of mass modeled by DDA. Different influence factors under investigated, including different delay...
Abstract In view of the problem strong rock pressure is easy to occur in coal seam mining western gully terrain. Based on conditions area under compound key strata Zhujiamao Coal Mine, methods similar simulation, theoretical calculation and analysis, numerical simulation field measurement are adopted. The dynamic structure model constructed, mechanism prevention control measures working face analyzed. research shows that upper slope section first undergoes rotary deformation, then chain...
In this study, we aim to probe the self-righting behavior of abalone on a substrate based experiments and mechanistic analyses. A successful process is observed, its critical condition in theory can be given terms rotation angle. Then, according moment balance potential energy minimization, required tension force foot for derived with respect The experimental result also shows that many cases cannot finish process. measurements tolerant strength muscle adhesion are both conducted. It judged...
Urechis unicinctus can utilize the ability of large deformation to advance in sands by radial expansion, just using a small force. However, U. skin and discrete nature make it hard analyze this process quantitatively. In study, we aim uncover burrowing mechanism granular sediments combining finite elements. We observe that will expand radially at head, then head shrink move forward. The expansion collapse let them flow, making easy advance. mainly relies on skin's sufficient pressure achieve...
