The main aim of mining is to secure profit.
This in most cases may be affected by mine operation cost if not properly managed.
Drilling and Blasting plays high role in ensuring profit in Mineral exploitation.
If the expenses incur on drilling and Blasting yield poor result, it tends to affect all the downstream operation cost.
It therefore good that blast design be done and monitored thoroughly by the Mine supervisor.
This is liken to safety in the mine, workers life is very important and must be given principal consideration.
Blasting must be done safely with no accident record or any form of misfire.
Explosive is dangerous when poorly handle but peaceful if well handled.
In 1960s before Alfred Nobel light up Explosive works, the use of Nitroglycerin Explosive base, TNT and puliminating Mercury & gold had cause great havoc due to there high sensitivity.
But for the discovery of Ammonium Nitrate base Explosive which are less sensitive but high exotically sensitive.
Explosive is now design to detonate under the availability of Shock wave from highly sensitive detonator and other Blasting accessories.
Conclusively;
Mine profitability is a function of;
1. Good Safety management System
2. Good mine operation system (development, drilling, Blasting, excavation, haulage & transportation)
The three key safety elements are very important to ensure mine safety.
These keys are:
1. Engineering
2. Education
3. Enforcement
Engineering safety element: This comes in the place of Engineering design, quality assurance and quantity assurance. Bench design work, mine design, blast design and other Engineering related min aspect must be given high priority.
2. Education safety element: All workers must be education on mine state view, wall stability, equipment usage and handling. Knowledge is safety: knowledge of mine operation and equipments goes a long way to remain safe in the mine.
3. Enforcement element: All safety rules, regulation, law, policy must be enforce on mine workers
