IMDEX addresses blasthole surveying issue with BOLT

IMDEX is looking to upend the standard drill and blast process with IMDEX BOLT™, a production hole survey tool for underground applications measuring blast hole deviation using a north seeking gyro.

IMDEX Commercial Manager – Underground Survey Applications, Mike Ayris, has been promoting the importance of surveying blast holes since he founded Downhole Surveys (DHS) in 1989.

DHS was majority owned by directional drilling specialists Devico and became part of the IMDEX group when IMDEX acquired Devico earlier this year.

For Ayris, the process is not drill and blast; it’s drill, measure, analyse and blast.

BOLT, meanwhile, is in the commercial prototype phase and has been installed at four sites with two trials underway.

Recent design changes have reduced the weight, making it easier to deploy overhead, thereby solving one of the key challenges of working in an underground environment, IMDEX says.

“BOLT addresses one of the biggest problems we have in blasthole surveying and that is the holes are drilled overhead,” Ayris said. “These can often be 5-m high. The only way of getting there and physically pushing a tool up the hole is from an elevated work platform from which the tool is pushed into the blast hole.

“IMDEX have created a method of deploying the tool from ground level.

“The original design of the BOLT had a depth limitation of about 20 m, but most of our clients are drilling between 25 m and 30 m and it is the longer holes that need to be surveyed because they deviate the most.

“A typical drive development from one level to the next is roughly 15 m but mining companies are investigating ways to double this length to 30 m as a way of increasing efficiencies and reducing costs.

“It now means the need to drill blast holes twice as long as previously. A lot of drill rigs are designed for 15 m not 30 m, so they are pushed beyond their capabilities which then causes deviation, among other factors.

“The consequence of blast holes deviating can be a stope hang up or bridging, where the rock is fired but doesn’t break or fall, forming a wedge. Once that happens there is no way of getting the rock out. Companies will try drilling beside the bridge and use explosives but it’s highly dangerous and very ineffective.

“Bridging is a major problem in underground mining, and blasthole deviation is one of the causes because if the blast holes deviate away from each other the explosive impact at the end of the hole is reduced.

“There are a lot of other factors, but surveying and measuring the deviation is one thing we can control by getting the information before blasting.”

Ayris said while engineers typically designed blast holes to have a maximum deviation of 3%, in his experience few holes fell within that specification, with some deviating by as much as 17%.

“If you look at the mining process, money is spent exploring from the surface, then getting the tenement lease, creating a decline to the orebody, doing the development drives, and drilling the blast hole,” he said.

“Drilling and firing is the last process, so you want to get it right.

“With BOLT we are trying to create a system that is on every underground mining operation so that blast holes are routinely measured. It’s not just drilling, filling the hole with explosives and hoping for the best. Now it’s drilling, surveying, reviewing and analysing the data, and making adjustments to the pattern based on that information before firing.

“It’s a very different way of thinking and we are challenging the traditionalists who just want to drill and blast. It is changing, it is definitely changing.”

Perenti secures largest ever Australia surface mining contract at KCGM’s Fimiston mine

TBS’ Collar Keeper blast hole solution goes commercial in Western Australia

Aquirian Limited’s TBS Mining Solutions Pty Ltd (TBS) has commenced commercialisation of its revolutionary Collar Keeper® System, with a fully commercialised, extended trial underway in Western Australia’s Northern Goldfields.

TBS is on-site with 60% of the mine site’s Epiroc T45 drill rigs converted for an extended commercial trial, it said.

This milestone follows the completion of its final in-field trials at the end of 2021, where 254 production holes were drilled, including 30 wet holes in difficult ground conditions, where The Collar Keeper System eliminated the requirement for costly and time-consuming collar piping, according to Aquirian.

While the ongoing COVID-19 outbreak in Western Australia delayed access to site, Greg Patching, Executive Director Business Development and Innovation, said: “We are thrilled to be finally in the field commencing the transition for our customers onto the Collar Keeper System. This marks a major milestone for the development and commercialisation of the system.”

TBS has also received strong interest from several overseas mining companies and received its first orders for a commercial trial to commence in Zambia in mid-late May, it said.

The company continues to work on the development of the Collar Keeper System, including expanding the range of drill rig applications and mechanisation of the system which will, in time, provide a pathway towards full automation for clients worldwide, it said.

The Collar Keeper System is a combination of Aquirian-developed, retrofittable drilling apparatus combined with its existing Collar Keeper. The technology represents a step change in managing blasthole quality and is targeted to provide a unique solution to a range of different blasting environments with global applications, the company said.

The initial focus for the technology is on mines operating in Western Australia with smaller-diameter holes in challenging ground conditions, where high-cost collar piping is traditionally used.

“The traditional method of collar piping has not changed in over 40 years and introduces significant hazards as well as cost, time and quality issues, and poor blast outcomes for clients,” the company said. “In addition, the poor blasting outcomes lead to further downstream costs in load and haul, and the processing of mined material.”

Epiroc boosts blasthole drilling power and flexibility with DM30 XC

Epiroc has introduced the DM30 XC blasthole drill for a variety of multi-pass rotary and down-the-hole (DTH) drilling applications, offering, the company says, 33% more power and many benefits to customers.

Built off the same platform as the Epiroc DM30 II, the DM30 XC is designed for maximum productivity and efficiency due to increased rotary torque, increased pulldown and a larger hole range capability. The DM30 XC is built to handle a 101-159 mm drill pipe and has a weight on bit up to 20,000 kg. The heavy-duty, crawler-mounted, hydraulic top-head drive drilling rig features a 9.1 m drill pipe change and a standard carousel.

“The DM30 XC is built tough for the most demanding jobs, and high quality at an excellent value is what sets it apart from other drills in its class,” Mark Stewart, Regional Business Manager, Epiroc Surface division, said. “The drill is designed for mining so the structural components will hold up to the heavy-duty cycles required in a mining drill. The robust frame and tower weldments are manufactured to last the lifetime of the machine.”

With a starter rod under the rotary head, the DM30 XC can achieve a total clean depth capacity of 45.1 m for multi-pass applications and 8.5 m for single-pass applications. High efficiency and a 1,136 litre fuel tank allow the rig to run for up to 16 hours before needing a refill for continuous operation. In addition, the smaller, compact footprint of the DM30 XC makes it easy to manoeuvre on tight benches and simple to transport over between pits.

No matter the customer’s need, the DM30 XC offers options to suit any application, according to Epiroc.

Customers can choose a low- or high-pressure compressor to create the right configuration for their drilling operation. A one-piece FOPS (Falling Object Protective Structure) rated cab with electric over hydraulic controls offers enhanced safety, visibility and operator comfort. The DM30 XC is easy to operate, especially for drillers who have experience in other DM series machines. The ergonomic controls layout allows immediate switchover from drilling to tramming mode, maximising time available to drill.

The DM30 XC is equipped with an Electronic Air Regulation System (EARS) that provides low load start up and easy adjustment of bailing air to save horsepower and lower fuel consumption, extending power component life and decreasing total cost of ownership.

Customers can add even more flexibility to their DM30 XC with Epiroc’s Rig Control System (RCS) Lite, which offers several safety and productivity features. It also provides a convenient foundation to add more functionality and technology options in the future without a major rebuild of the machine, Epiroc says.

RCS Lite allows all Epiroc rotary drills to have the same on-board display and system for consistent operator training and service. The modular RCS Lite solution offers customers three different packages to choose from.
