MNM Safety Alert Explosive and Blasting Safety Mine
Blasting safety demands the highest level of attention among employees working in metal and nonmetal mining. Since 2010, seven miners have died at mines as a result of flyrock, misfires and toxic fumes. Two miners died in one incident in 2013. All mine operators, independent contractors and miners must follow strict explosives safety procedures to prevent fatalities.Professional Masters in Mining Engineering and Management,The Professional Masters Mining Engineering and Management (MP-MEM) is a new degree program focused on the practical application of technical, financial, management, and other linked disciplines that make up the mining industry today. It was developed on the premise that in addition to technical capacity, future mining industry leaders will need to:
CDC Mining Handling Explosives in Underground Mines
Part construction crew, part demolition crew: underground miners deal with both creation and destruction in a typical day. Though explosives are safer than ever before, caution is still needed when dealing with such a powerful force. This video teaches new miners basic safety rules to keep from hurting themselves or others while handlingExplosives and Detonators Mining and Blasting,High VOD explosives are more suitable in hard rock and low VOD in softer rock. Generally, explosives with a lower VOD tend to release gas over a longer period and consequently have more ‘heave’. The VOD range in commercial explosives is 2500-7500 m/s. 3.3 Density The density of a explosive determines the charge weight per meter of hole.
