• Experimental and numerical analysis of dynamic fracture processes in rock and rock-like materials using NRC vapor pressure agent 

  Min, G; Fukuda, D; Di, W; Liu, H; Kawasaki, S; Cho, S [Conference-Full-text]

  This study investigates the fracture characteristics of rocks and rock-like materials subjected to the Nonex Rock Cracker (NRC), a vapor pressure crushing agent. The NRC generates vapor pressure by instantaneously vaporizing ...
• Prediction of overbreak phenomenon in tunnel blasting using ORF index 

  Sato, N; Im, H; Nakazawa, Y; Jang, H; Ohtomo, Y; Kawamura, Y [Conference-Abstract]

  In the drill and blast method, one of the most critical issues is overbreak. Overbreak leads to decreased work efficiency and increased operational costs, and it is recognized as a problem that needs to be addressed. ...
• Development of a numerical simulation method for complex fracture process of rocks based on 3-D ECZM-FDEM using GPGPU parallel computation 

  Takarada, K; Fukuda, D; Di, W; Liu, H; Ogata, S; Maeda, Y; Min, G; Kawasaki, S [Conference-Abstract]

  For the developments of surface and underground mines, numerical simulation has been regarded as a highly crucial approach in terms of mining design and safety. The combined finite-discrete element method (FDEM)[1] has ...
• Enhancing Co2 mineralisation in steel slag with amines for developing a waste to construction material 

  Takebe, K; Elakneswaran, Y; Yoda, Y; Kitagaki, R [Conference-Abstract]

  Global warming has become an urgent issue due to the increasing atmospheric emission of CO2. In Japan, the steel industry emits a large amount of CO₂ and produces steel slag as an alkaline waste product. Using this steel ...
