Drilling and Blasting an overview ScienceDirect Topics

10/08/2011· The preceding analysis indicates that an increase in drilling and blasting energy can increase the efficiency of total energy in the whole size reduction system. Moreover, a total of 210 blast tests show that the specific surface created by blasting in the unit of cm 2 /g linearly increases with an increasing specific energy consumption in the unit of J/g, where g is the grams of the rock [22] .

Blasting Best Practices T.M.I.

The Blasting Process. Using explosives to open up an area, demolish structures or dispel rock is a complicated task because there are numerous risks. However, you can break the procedure into a few core parts. The basic steps of the blasting process involve: Evaluating the zone; Placing the explosives; Initiating the blast; Clearing the area and reinforcing the site; 1. Evaluation of Blast

Underground mining (hard rock) Wikipedia

One of the most important aspects of underground hard rock mining is ventilation.Ventilation is the primary method of clearing hazardous gases and/or dust which are created from drilling and blasting activity (e.g., silica dust, NOx), diesel equipment (e.g., diesel particulate, carbon monoxide), or to protect against gases that are naturally emanating from the rock (e.g., radon gas).
