Jol Jardine, mine manager of Terramin Australia’s Angas Zinc Mine, is a finalist in the 5th Annual Australian Mining Prospect Awards.
Jardine has worked in underground mining for over 18 years and as such understands the pitfalls often associated with the career. Recently, he devised a unique plan that allowed his minesite to achieve its goal of deepening the Boxcut.
The mine employed a civil construction approach to tunnel excavation to combat a wall of clay and silt.
According to the mine manager, an innovative approach to mining through the 80 m stretch of silt, patience and a lot of hard work, got the project over (or through) the initial hurdle.
The approach involved taking a civil construction-type approach to tunnel excavation, using a drilling jumbo to erect initial roof support, and cautiously digging out the face in two stages.
As hard rock appeared in the decline floor, and then increasingly became part of the advancing face, the material had to be broken in a way that would not shake up the silt too much. Never one to take the credit, Jardine paid tribute to the mining crews working on the decline, affectionately known as ‘the silt miners’ or ‘sultans of silt’, who triumphed in the face of a particularly challenging job.
Angas is expected to produce up to 65,000 tonne of zinc and 24,000 tonne of copper-lead concentrate annually when in full production.
The mine is expected to boost the local economy by $29 million.
