Safeguarding of Blast-affected Areas.
Proc Soc Explos Eng 10th Annu Conf Lake Buena Vista Florida 1984 Jan; :20 pages
A recent Bureau of Mines analysis has shown that failure of blast area security systems is the major cause of mine blasting accidents. Accidents occur during scheduled blasting because of failure to clear the blast zone, inadequate guarding and failure of personnel to follow instructions, retreat to a safe location, and/or failure to take adequate cover. The high incidence of blast-site security- related accidents could be considerably reduced by increased attention to improving minesite blast-guarding practices. Mining and Marketing Associates, Inc., conducted research under contract to the Bureau of Mines to determine the state-of-the-art of blast area guarding and to recommend safe procedures and areas deserving of future research. This paper is a summary of that research. Case studies of current blast area guarding practices at two surface and three underground mines are presented; practices at these five mines are considered to be much safer than those generally found in the industry.
