By definition, I describe mineral as solid inorganic naturally occurring matter, that is been generated during magma eruption through sufficient time cooling and interrelate and exchange of element in the liquified rock lava.
The mining engineer as well known by other disciplines involve themselves in getting the ore from the Earth crust and refining it to fit end user's need.
The extraction process begin from altering the Earth land form through wide range of excavation and degredation attempt to get the so called overburden material removed in order to gain access to the enriched ore vein.
Emphasis on Bowen series reaction*: During formation of mineral, the cooling time tenders to affect the location of each precious mineral, some tend to form at deep depth due to the slow rate of cooling. Slow cooling support fast and bigger growth of mineral size. The bigger the mineral accommodation, the higher the economic value. This condition makes the ore deposit locate in strategic position where need arise for size reduction to ensure the valuable minerals are easily separated.
Ore is an accumulation of valuable mineral existing in an economic quantity. This ore is what the Mining engineers want and it existence can only be found in rock Mass. In addition, the ore block do not exist alone as an entity but usually bond with the parent rock which can be igneous, sedimentary or metamorphic rock.
The host rock may exist as outcrop or deep depth rock Mass which becomes impossible to move directly to the processing plant for libration and separation process.The quest bring about ways to reduce the rock mass and free the ore block for further ore dressing. Transportation of run-off-mine is capital expensive and also the mine-to-mill operation cost is high!
Innovation attempt in the 1900s to begin the use of black powder aim to assist and improve mining operations.
This improvement covers the production and cost minimisation.
Likewise the 1960s Innovation of detonation cords and cap by the Dyno Nobel group assist the safety and effective use of the energetic material.
Blasting Is important but must be safely carry out to ensure the reason for blasting is not been blasted.
Let your manager be aware!!!!
Campaign against unsafe Blasting
Say no to poor and unsafe blasting operation.
Both civil works and mining operations required blasting activities to get the rock Mass size reduced or get the obstructing rock casted out from the road map.
Using explosive in a bit to generate the needed energy can be highly dangerous if not properly handled
Many quarries had begin blasting long year ago without any plan, without any post blast check, without any preblast planing. Fire work is not good when out of hand and this can happen when excessive powder factor is use or there is existence of misfire due to unforeseen circumstances.
Blasting is much more dangerous and must be done safely.
This campaign is to sensitize all quarry owner, manger and mining engineer on the need to put proper consideration on proper and safe blasting.
Advice to mining industry:Things to enhance your blast safety
1.Get the blast design right
2. Conduct your preblast checking and take note of various structural features that needs design attention
3. Identify any hole with fractures and note any existing dyke and sills as intrusion
4. Supervise the handling and transportation of all explosive material from magazine to site and from site back to the magazine
5. Monitor all explosive usage and ensure due procedure is follow during charging and chaining to avoid unnecessary fire cut, misfire and other arising issue with blast impulse distribution.
6. Provide good policy for you blasting team and monitor all unsafe act and conditions with instant action
7. Give all blasting operation special team for emergency response and safety team.
8. Ensure all clear surveillance is made available and active for all blast operation.
Let make blasting a good blasting and not a Killing or ground damaging blasting.
We want the ore for the people, then we must not create dead trap for the people through landslide, wall fall and holing due to over break during blasting.
The explosive energy is for peace and not for war
