physical & mechanical rock properties definition of stress, strain and fundamental elasticity property experimental method of rock failure and strength elastic and rheological property rock classification method based on mechanical properties like whole or deformation process, etc. Core sampling of domestic main rock types and making specimen Strength and deformation properties, Tunnel, location selection for tunnel and slope construction, investigation of basic rockmass, planning, construction, measurement and management geotechnical and rock mechanical method of investigation and calculation for appropriate supporting system. Classification, production of industrial explosives and performance test, principles of blasting agents and performance test content of "Enforcement Decree of the Control of Firearms, Swords, Explosive" and related Act and subordinate statute. Engineering usage method of industrial explosives, management method, tunnel and surface blasting design method blasting vibration and noise pollution, etc. We will be learning above and practice all sorts of tests and design.
2.Research Areas
○ Rock Mechanics
Research in rock mechanics involves laboratory and in situ testing of rock properties. A large number of on-going projects involve the study of rock mass structural characteristics vis-ă-vis the rock properties obtained from specimens in conventional lab tests. New projects include the use of geostatistics for optimal geotechnical site characterizations and its application to predict or analyze the spatial distribution of characteristic parameters of rock joints as well as probabilistic risk and uncertainty analyses for mining and civil structures.
Newly developed methods of site characterizations include space-based technologies for geotechniques and resource engineering, structural analysis of rock slopes, tunnels, and underground openings for mining.
○ Rock Fragmentation
Research in rock fragmentation focuses on both blasting and mechanical fragmentation techniques for underground and surface mines. Blasting studies include the design of optimal blast patterns and stress wave propagation, the dynamic responses of earth and surface structures to blast vibration, and the determination of detonation parameters of non-ideal heterogeneous explosives containing gaseous and liquid phases.
Mechanical rock fragmentation research includes the interactions of the machine with the rock, for lowest energy expenditure. We study continuous miners, road headers, tunnel boring machines, and surface miners.
○ Underground Construction
Underground construction applies mining and civil engineering technologies to the excavation of underground structures. This area of study includes all aspects of underground site characterization, opening design, excavation of openings, supporting systems, project scheduling, costing, ventilation, ground control, and equipment selection.
