4. 2. Rock Mechanical Effects of Cement Grouting in Hard Rock

   Author : Staffan Swedenborg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : A pre-grouted rock mass is subjected to stress re-distribution as the tunnel excavation progresses. The strength and deformation characteristics of grouted rock joints are therefore of interest in any effort to predict the rock mechanical behavior as well as the failure of sealing in a grouted rock mass.

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underground mining; Sublevel caving; Rock mass quality; Borehole filming; Borehole quality; Borehole stability; Borehole instability; Drill monitoring technique; Measurement While Drilling MWD ; Hydraulic in-the-hole ITH drilling; Drill system behaviour; Principal Component Analysis PCA ; Geo-mechanical model; Chargeability; Fracture zone; Shear zone; Cave-in; Cavity; Rock blasting; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : For an efficient mining operation, it is essential to have as much information as possible aboutthe ore to be excavated and the rock masses surrounding the ore. Geological information andthe content and distribution of extractable minerals, are central concerns for long term mineplanning. READ MORE

6. 4. Influence of heat on the physical and mechanical properties of selected rock types

   Author : Christine Saiang; Karl-Johan Loorents; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunnel fires; heat influences; temperature increase; mechanical properties; physical properties; micro cracks; mineralogy; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : Impelled by the increase in the number of tunnel fires in the last decade alone, wide spread attention has been drawn towards tunnel fire safety studies. Many of these fires occurred in road and railway tunnels involving vehicles and trains. READ MORE

7. 5. Acoustical experiments on the non-linear and non-equilibrium behavior of rocks

   Author : Babak Khodabandeloo; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The study of dynamic behavior of non-perfect materials, such as rocks, is a rich topic for developing sensitive material evaluation and damage detection techniques. It has extensive applications in a variety of fields such as Physics, Geology, and Aerospace, Mechanical, Civil, Petroleum, and Material Engineering. READ MORE
