ASM Needs help with safety

Blow out and flyrock is one of the evidence of poor and unprofessional blasting operation.

This can result from poor steaming and overloading of holes and sometimes result from low charge weight.

Energy is define as the ability to get the job done, the capacity to overcome the energy barrier.

There are many ways to generate energy but for rock breaking, the use of explosive had been the most adopted means since 1900s. In every proper work done, professionalism is very important. Lack of professionalism result into disaster and accident. Since the aim of mining is to promote safety first through new innovation, inventories and safety management system, then the call for help to ensure this is achieve in Artisanal and small scale mines is important.

Fact

The artisanal miners will keep existing in the stope of mining operation as they has always be because if the following reasons:

1. challenge of start up capital in developing countries to set up large scale mine

2. large scale mines will for sure always go for huge deposit, neglecting placer/alluvial deposit with low grade and non uniformly distributed. #mining 

Artisanal miners need assistance and help to ensure all operations are safely carried out.

Reason for urgent response

The approach adopted by the low income Miner to extract alluvial formation tends to affects the environment, damage water, land and even air through pollution and acid mine drainage.

Aside from this hazardous effect, small scale mining operations working with insitu hard and soft rock sometimes engage in drilling and blasting operation.

This operation in most ASM mines are performed with less consideration to safety. Getting the explosive charge quantity that will break the rock down safely without any environmental effect becomes important. likewise understanding the behavior of this explosive generated shock and gas energy also contribute to ensuring the Earth crust condition after blast remain stable and safe for human existence.

Th question now arise that who will sensitize the ASM and other quarry workers about the safe design and execution of blasting in Most Africa and less developed country.

Explosive is for peace and not war

Let get the across to the ASM operators about the best and safe usage and handling of explosive but during transportation, storage and usage.

the mission is to go for safety first!

As all the mining worker must return back home to enjoy nice dinner with their family.

blasting aim to support innovation, development, and human existence beautification.

mine the ore safely

get the ore peacefully

Blast it safe to safe your world

Brief Summary

We must be alive to get all the money we are dreaming and thinking about! Mining still remains the most lucrative business in the world with high impact on Technology Development.

But the level of safety at the blasting operation cycle is minimal due to lack of sensitivity despite millions of Research work on this area.

This article was put together By Taiwo Blessing Olamide to sensitize the World mining sectors on the need to get involved in small scale mining to avoid unforeseen disaster.

Looking are many developed countries it becomes clearer that they are all functioning well in their large scale mines. Likewise the developing countries, they tends to have some level of success in the record of medium scale mining operations.

Taking a look at the small scale mining operations as a case study Nigeria and other Africa countries, most mining operations in artisanal and small mines are poorly monitored and design. Professional Mining engineers are kind of Given up on the local miner, instead of any form of assistance they set their compass on the direction where large mining thrives. Less attention has given to help, improve and monitored small mining operations because the large scale miners have all Earth equipment to get their mine cleaned and discretely planned.

This become my view and concern! That, though the small scale mining operators are abundoned but with time the large scale mines will soon fold up, reach the ultimate limit and come back to the small scale sites. In addition, the small scale miners might later cause damage to the Earth and bring aftereffect implication on the large scale mines and human existence at large.

Small mining firms are known for less safety concerns, less safety management and supervision.

looking from the direction of Blasting, small scale miners are not much concern about the effect of flyrock and it's causes, better worth how to minimize it.

They are less concerned about the effect of timing on blast fragmentation (Appreciating Professor Takis findings at Queen's University). This sectors are less aware about the aftermath effect of generated shock waves from excessive powder factor, how it can over break the wall, damage the unmined rock mass and reduce the stability of the mine slope completely.

Though we have our own mine safe and try not to show concern for the poor miner, neither do we have any plan to train, sensitize them on what they don't know. Before we try to mine for our own profit and mine development alone is time to begin a sustainable mining that check out others operation to avoid the future damage which is possible of affecting our mother Earth.

The ground itself has a stable stress field before the disturbance team called miner came, the induce stress resulting from excavation is capable of shifting all stress equilibrium into stress instability if proper control is not put in place. Each tectonic plate has it own respond to all the generated dynamic waves. But a time shall come when the plate will no longer be accommodative, then what can be done?

prevention is better than cure!

say no to poor blasting

support through mentorship, surveillance and supervision all blasting

manager must now be concern about the report of all blasting, not just how much tonnage do we get but how safe was the blast.

safety first

Campaign Slang:

Before Fire in the Hole, Safety must be assured

Mine is safe

Blast it safe

Check!! Check!! And recheck before putting fire

The beauty of a Good blasting is safety: Go for safety to safe the world

Why Blasting?

The rock Mass contain the ore mineral which is the mining engineer major target. Mineral resources are inevitable material needed for Technological innovation and national development. The place of this mineral resources can not be suschanged neither can it be replaced with synthetic materials.

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
