METAL/NONMETAL MINE FATALITY -On September 7, 2011, a 30 year-old miner with 1 year of experience was killed at an underground gold mine. The victim was on a ramp waiting for a blast to be initiated. When the round was initiated, small rock and debris traveled through a 3-inch diameter diamond borehole, striking him.
Plug a diamond drill hole that intersects any opening and map the hole. During blasting operations, consider mine specific conditions, including diamond drill holes and rock strata, and establish mine policies and procedures to protect all persons. When developing a blasting plan, make sure all drilled holes and open passageways that intersect the area to be blasted are known and taken into consideration before initiating any blast. Use a central blasting system and schedule blasting between shifts or on off-shifts when no one is present. Train persons to identify hazards associated with blasting activity and take action to correct them. Never initiate a blast until the blast area has been determined to be safe and all persons have been evacuated from the designated blasting area. Take special precautions to ensure that all roadways and regularly traveled areas are blocked to prevent access when blasting is being conducted.
