Regulations require all underground mines to have fully-trained and equipped professional mine rescue teams available in the event of a mine emergency. MSHA’s Mine Rescue Instruction Guide (IG) series is intended to help your mine to meet mine rescue team training requirements under 30 CFR Part 49. The materials in

Subdrill - The Underutilised Blasting Parameter January 2020 Use minimal subdrill and if the rock mass properties are favourable, use no subdrill at all. Negative effects of using long or excessive subdrill include: Wasting drilling and blasting time, resources and expenditure.

Blasting trials in the 1.6 metre high stope had indicated a three row drilling pattern with the centre row staggered, and a spacing of one metre between holes in any one row. Blasting using cordtex and Magnum cartridges was very successful, leaving full barrels along the stope. With limited blasting it was difficult evaluate rock throw.

Air consumption. an additional factor in selecting the optimum blasting nozzle, is closely related to the cost of abrasive blasting. Abrasive flow rate, nozzle pressure, and air consumption for each blasting nozzle along with abrasive valve opening are summarized at Table 3. At a similar abrasive flow rate ( 1,300 kg/hr), the air
