RUC Cementation Mining to carry out raiseboring at Bellevue gold project

RUC Cementation Mining has been awarded a raisebore contract at the Bellevue gold project, 40 km northwest of Leinster in Western Australia.

The project, which is valued at A$15.8 million ($10.6 million) over 28 months, provides for RUC’s Raiseboring division to establish vent rises, return air rises and underground escapeways at the underground mine.

RUC, a subsidiary of the Murray and Roberts Group, also completed several raisebores at the Bellevue gold project during the previous operations, project owner Bellevue Gold said in a separate announcement earlier this week.

RUC calls itself the industry leader for raiseboring, having proprietary techniques and equipment, cost saving initiatives and a localised offsite support centre based in Kalgoorlie, Western Australia. It says it is also focused on delivering services with good environmental, social and governance practices, which align with Bellevue’s strong commitments to be Australia’s first carbon-neutral gold producer.

Bellevue is forecasting production of 200,000 oz/y during years one to five at an all-in sustaining cost of A$922/oz ($618/oz) at its operation.

RUC Cementation ties in DaveyTronic detonators to underground mine network

RUC Cementation Mining Contractors says it has helped Davey Bickford Enaex achieve a new blasting first with its DaveyTronic underground electronic detonator blasting system.

The contractor has implemented “Safety First Firing” with DaveyTronic to allow it to fire blasts over the established communication system at one of its contracted operations.

RUC said: “This will enable RUC to wire in development faces as they are charged, saving the run around at end of shift firing with wiring in conventional electric detonators and ensuring the integrity of the connection throughout the shift.”

RUC believes in the not too distant future it will be able to integrate the firing system, remote fan start-ups, and gas detection system to make the firing and re-entry of the mine as efficient as possible.

This is a first for Davey Bickford Enaex using the existing fibre-optic network to set-up a secure blasting system underground, RUC said.

RUC Project Manager, Dave Sheppard, said: “This is an exciting time with the implementation and operation of our digital projects. The remote gas detection system (Smart Gas monitoring solution) allows us to monitor air quality from surface and, in conjunction with surface-linked firing, allows us to save up to half an hour per shift with re-entries – effectively offering a 5% productivity improvement.”

InSig Technologies’ Smart Gas solution reduces re-entry times at Mount Morgans

InSig Technologies says it and its partner company, RUC Cementation Mining, have successfully installed and commissioned its Smart Gas monitoring solution at the Mount Morgans underground operation in Western Australia.

This solution incorporates several fixed gas monitoring stations situated strategically throughout the underground mine, with these stations providing real-time gas level readouts to the control room located on the surface, it said.

It follows on the heels of InSig Technologies installing an underground Wi-Fi network at the mine in the March quarter, which it and RUC said could then lead to a ventilation on demand solution with the ability to monitor air quality from the surface.

The Smart Gas monitoring solution provides RUC, which provides full underground services to the mine, with another level of comfort and safety knowing personnel are not operating in a hazardous environment throughout the shift, InSig says. “It also allows for quicker re-entry times and staged re-entry to the underground mine workings by eliminating the requirement for personnel to physically check each level is clear before opening the workings.”

While it is early days for the system, re-entry times have already come down by 10%, according to InSig.

Mount Morgans, owned by Dacian Gold, consists of the Jupiter Mine Area open pit and the Westralia underground mine. The latter mined 200,775 t at 2.9 g/t Au for 18,409 oz contained during the March quarter.
