GIANT MINER

Truly energy can neither be created not be destroyed but can change from one form to another. Explosive are chemical compound which at detonation releases specific joules of energy. The energy release during Blasting travels in form of shock  wave, heat energy, light energy, sound energy and gas energy. The first release is light energy followed by shock wave which is associated with heat energy. The last release energy is the gas energy which finalize the work need to be done by Explosive charge. Energy is defined by various scholars as the ability needs to do work. The work before Explosive during detonation is to explode rock mass, fragment rock mass, throw rock piles and to  cause other negative effects like ground vibration, airblast, and rock projection (flyrock) Sequence of Explosive energy ULTILIZATION during Blasting  The light energy travels faster than all others energy, it shows the initiation direction of Explosive charge detonation.  Check t...

Pre Blasting and post Blasting inspection for data collection and blast design is very important so as to performance a profitable and productive Blasting. Some of the pre-blasting inspection carried out before Blasting includes; 1. Ground water condition (in-hole water check) 2. Rock face discontinuity mapping 3. Drilling parameters collection. 4. Free face checking. 1. Ground water condition (in hole water) Water may be present in the mine either through surface inflow or underground water outflow. Ground water condition affects Blasting materials, expecially when using a non water resistant Explosive like ANFO. This may result into MISFIRE and poor fragmentation. All holes must be inspected and those with water should be noted. Water tend to reduce the sensitivity of non water resistant Explosive. Explosive like Dynogel and emulsion gel and other water resistant Explosive should be use in noted water filled holes. Hole with water can also be drained or flush by high pres...

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...
