Recent advances in excavation, design and support methods: A case study of Mangdechhu Project, Bhutan

P.K. Mishra, R.K. Chaudhary, P. Punetha
Construction of hydro power projects in the Himalayan region poses various problems which can have direct implication on the cost and time schedule of the projects. Varying geological conditions necessitate use of modern methodologies for ensuring stability and overall time bound completion of the project...

3D-Numerical simulation of a mine using cohesion-softening, friction-softening and hardening behavior

P.K. Rajmeny, PK Jain, Vakili Abouzar
Numerical modeling is a potent tool to evaluate stability and to assist in long term planning of a mine along with predictive modeling of planned mining situations. However, selection of proper input properties regarding the rock mass still intrigues the Rock Mechanics community. A well-documented case...

Rib geomechanics: Its impacts in coal pillar extraction

Singh Satyendra K, H. Agrawal, A.P. Singh
In Bord & Pillar (B&P) depillaring, there are redistributions of mining-induced stresses on acontinual basis, primarily with apronounced effect on the natural supports - ribs and stooks. A rib need to be stable on temporary time-frame such that (a) it should provide adequate safety to men and machines...

Application of nanotechnology for underground roof bolting

Ramayya M S Venkata
Rock re-inforcement in Underground Coal mining is generally being done by roof bolting. Roof bolting is a pre-requisite and important activity for safety and high percentage of productive extraction of the Coal from Underground Coal mining. Nanotechnology and Nanoscience is the latest development in...

Advances in rock mechanics and future trends

B.B. Dhar
Rock mechanics is an engineering discipline which is as old as 1770s. Coulomb of Mohr-Coulomb failure criteria fame carried out tests on rocks and presented the results in a paper to the French Academy. After about 150 years, Griffith proposed his theory of brittle material failure in 1921. At about...

Stability of underground mine workings due to surface blasting

P.K. Singh
Blasting in the mining industry is being transformed, and can no longer be treated as an art or a practice purely dependent upon experiences of individuals. Examples of key drivers that have demanded consistent and more accurate blast results are initiatives to control pit-wall damage to help mine operators...

Rock blasting technology: The way forward

V.R. Sastry
Main objectives of rock blasting are to fragment the strata for achieving required yield with desirable fragmentation and minimum side effects. Though the side effects like ground vibrations, noise, fly rock, etc. cannot be avoided completely, these can be minimized by selecting suitable explosives,...
