Chute Technology’s world-first chute design cuts costs and downtime

A multidirectional rotating underground coal chute system that can be installed in less than a single shift at a typical mine has been developed by Chute Technology in what the Australian technology and manufacturing partnership believes is a world first.

The cost-saving universal chute – which can rotate output through 160 degrees left or right – can remove completely the need to custom-manufacture individual chute types to fit the confined spaces and particular angles of individual mines. 

The versatile bolt-in system – comprising a complete integrated structure from head end to conveyor outlet – features a rotating outlet beneath the head that can be angled to any position required to facilitate product flow.

In addition to radically reducing the labour required for manufacture and installation, the chute’s ability to be installed in a fraction of the time of custom chutes minimises downtime by keeping production moving when chutes wear out.

“This is a brilliantly simple breakthrough in cost and time saving at a time when the mining industry needs it most to maintain production. The benefits are obvious when you look at the basic concept, but we don’t know of anywhere else in the world where it has been done,” says Chute Technology Partner Mr Tom Woods, whose experience of coal chute manufacture through family company T.W. Woods Construction extends back more than 40 years.

The new chute system – of which the first example has already been produced – is the result of the analytical, design and manufacturing experience of each of the three Principal Partners in Chute Technology, who have combined experience of more than 80 years in a wide variety of resource industries including coal, iron ore, alumina and limestone across Australia, the USA, South America and South Africa. The company’s technologies are also applicable to gold, nickel and other bulk minerals and ores.

“A great thing about the new system is that it is easily configured to flow with the hugely diverse geology of mines throughout the world, which have shafts joining other shafts at whatever angles the geology and conditions underground dictate.

“Instead of having to engineer custom-fabricated chute systems to suit unusual angles, this system just bolts into place in a fraction of the time and at a fraction of the cost in time and money.

“In addition to savings in extending mines and adding new production, the chute system is far more time and labour-efficient in replacement of worn-out chutes, when you usually have to dismantle the old and install the new piece by piece. This one just slots into production virtually overnight.  

Chute Technology Pty Ltd combines the local and international manufacturing experience of T.W. Woods, represented by Director Tom Woods, with the similarly broad engineering and technology experience of Engineering Consultant Dennis Pomfret of Dennis Pomfret Engineering, and Design Engineer Gary Telford of McKajj Services, which contributes extensive design engineering, detail drafting and project management experience.

A bonus of the system they have produced is that it is designed from the outset to solve spillage and conveyor bulking problems common in coal mining and coal handling facilities.
