,Rock–Explosive Interaction During Underground Blasting,can optimize the design parameters by assessment of rock–explosive interaction to achieve the desired output. The expected outcomes from underground blasting would be different under varying geomining conditions. The optimum breakage of rock mass with enhanced pull and reduced overbreak is expected

Drivage Excavation Using Drilling and Blasting,ng. The burn-cut blasting pattern is used in all the Indian metalliferous mines to make drivages. The pattern consists of a set of holes to be blasted against the free face provided by relief/reamer holes. The design parameters in burn-cut face blasting include drilling pattern (burden, spacing, bla

Underground Ring Blasting,tion pace due to the use of large diameter drilling and blasting. However, this method has many associated operational challenges. These challenges have been overcome using the technological innovations. It has been possible to undertake ring blasting up to the depths of 50 m with the help of multi-

Blast-Induced Hazards,be a threat to the structures. Accordingly, there is a need to devise the controlled blasting pattern to safeguard such structures. The structures to be protected from blast-induced hazards include the surface residential structures, industrial buildings and underground structures. The threshold gro
