Open pit mines are built by digging in steps or benches at specific intervals based on the type of mining machinery and transport used. To minimize the danger of falling rocks compromising the structural integrity of the pit, the walls of the pit are dug at an angle that is less than the vertical. Usage of concrete, rock bolts and cable bolts to prevent the falling of rocks is common. In addition to rocks, the damage to an open pit mine could also be caused by the walls weakened by the holes drilled to ease water pressure. Like open pit mines, underground mines are dug at strategic locations charted out after careful analysis of the terrain and the general mine plan. After digging an underground mine, pillars need to be erected at appropriate intervals to prevent collapsing of the mine roof. The mining industry of Australia employs drill and blast engineers to take a leading role in the construction of the open pit and under ground mines.
Drill and Blast engineers are engaged in creating a open pit or underground mine. Drill and Blast engineers primarily work with explosives and charges to break down rocks, mountain surfaces and earth to create a mine. Drill and Blast engineers calculate the pressure points of the structure that has be blow up and devise a blast plan. With the help of a blast pan, explosive materials will be placed in strategic positions by drilling holes on the surface.
The mining industry in Australia expects the Drill and Blast Engineers to take up challenging jobs on a daily basis and keep the mine development process proceed without any hurdles. Drill and Blast Engineers are expected to provide technical assistance thereby ensuring that he mine development activities are carried out in an environmentally friendly, safe and economically viable manner adhering to the safety standards set by the mining industry in Australia. In collaboration with a team, the Drill and Blast Engineers should develop strategic drill and blast management plans in the mines of Australia. The mining industry in Australia also requires the drill and blast engineers to help in drafting the budgeting and forecasting o mine development plans.
An unflinching focus on the safety and security of mines is a mandatory requirement from the Drill and Blast engineers since they are responsible for the lives of mine personnel and the mine infrastructure. Aspiring candidates are required to have relevant drill and blast experience with good communication and soft skills to act as a liaison with various mine departments ensuring safety and punctual completion of the projects. Eye for details, good analytical and problem solving skills are a great plus in a candidate.
The drill and blast engineers should hold a Degree or a Diploma in Mine Engineering in addition to prior supervisory experience within a drill and blast operation. The successful candidate will be rewarded with an attractive remuneration package which will be dependent on experience and qualifications. The Mining industry of Australia pays $85000 to $13000 to start with and perks like FIFO, general health, dental and life insurance cover.
