IF SAFE AND PRODUCTIVE IS MINABLE
Explosive charge can vary from rock to rock due to the different in discontinuity property, rock Strength, rock impedance, rock type, rock grains packing and other non controllable factors.
Make a good pre-planning before Blasting and also use test Blasting to build a standard blast design for your mine. SAFTEY and Profit must be balance.
Our miners must return home to their children and wife safely. We mine the ore and keep the earth healthy for the next generation.
As you resume to morning, evening and afternoon shift take note of the possible hazards in the mine due to previous operation. Check the mine face in case of overbreak, check the ramp in case of slabbing effect, check blast pile for undetonated Explosive charge, cord, check drilled hole dimension and accuracy, check the operation Condition of your equipment. Check records from last shift person, try and look into any recommendations and complain in the Reports to put them in order. Understand the production target for the day, Design the blast that will produce the target in a good fragment, plan on need items to make the blast and mine run safely and efficiently.
Reach out to your team, be concerned about their welfarism, get your team into action as a team player, start mining with prayer and end with thanks giving. What we do is simple, liberate the ore from the host rock, load the material into a haul truck, stock pile the run off mine at the processing plant.but more than this, we check for consequences of every operation, carryout job safety analysis JSA, adjust blast controllable factors to sweet and blend the uncontrollable factors. Work with the design slope angle to avoid increase in stripping ratio,and to ensure safety in place of slope face stability. Mining is just a profession you will like to involve in, let the firing Begins
As you extract and exploit the earth, check the health of the lithosphere also, treat any form of weaken rock stability Malaria, every possible slope discontinuity daylight fever in the rock face, every typhoid in the continuity of intact rocks must be treated with perfect design. Some need to be eliminated, suspended, isolated, control with Engineering design, administration policy of avoid high risk level on workers through the use of safety PPE. Let understanding be available for all your workers, let all Engineering design be with optimum factor of safety and let all policy, rules and regulations be fully enforced by concern supervisor and Mine managers. In most mine oversight is the disease consuming their profitability, managers should be involved and carry along in all operation. Blasting most not be done without the *ALL CLEAR* order from the blast coordinator or Blasting Engineer. Let all blasting time be consistent and made known to all workers, let all alarm be sound at least three times before the blast and then after the blast. Working equipments should be trekked away from blast zone do not use them as shield to hold flyrock. Get the machine to a safe place, let all Explosive be use without additional combustive material. Don't do this to increase Explosive Energy it affect the Explosive design OXYGEN BALANCE.
Have an emergency response team, and incident Management plan to handle any form of mine emergency, let all policy be in place and visible to all workers. Where Blasting is carried out in unstable temperature or pressure condition proper Explosive and Blasting accessories selection must be done and adjustment must be done to blast design to suit the Working condition. Let all holes be checked properly for in filterated edge water before charging, using ANFO swelled or dissolved in water result in the release of Carbon monoxide fume or other notorious gases with brownish or pale brown color which is toxic and irritants great source of harm to human lungs and health generally. Let mining be a safe Mining and blast be a safe and productive mining. Blast fragment should contain less than 5%undersize and oversize material to ensure smooth run-in of processing plant as planned. Plan ahead of raining season also, design your dewatering system and make it clear to bear your producing capacity. Disappointing buyer is a sign of demolition in market and a sign of reduction in mine revenue. Raining season is know to be a time of low production due to limited access to the mine and low efficiency in productivity, poor pit accessibility, small working space, low haulage operation, unstable mine face due to increase in material bulk density, high rate of misfire. Plan ahead, work ahead and work safely.
Let you mine be safe and let you workers be secured, make environmental health and safety garantee for community, release of dust, ground vibration and high decibel noise during your Blasting and other operations will add to the people's problem, likewise projection of rock debris can break human skull and tear brain appart, it can also break door, crash cars and even amputate body part avoid over charging of hole and control your fly rock. We must make peace with nature to make peace with men, control the rate of ozone layer depletion, reduce rate of green house gases release into the atmosphere. Let make mining work out, if the material is not mine, then it is grown. Industry feed on us let production rate increase to reduce poverty rate through production of materials, employment, source of income to people, infrastructural development, social economy growth among others. Mining Engineer is a profession and not a hand skill, let all company be managed by competent person, supported by as many as needed assistance to make things work.
