AUTOMATION Automatic for the people Multi machine automation for LHDs, new tele-remote projects in China and new guidelines on automation implementation in Western Australia – progress with mine automation continues apace, reports Paul Moore utomation is no longer just represented by a handful of isolated and idealised test areas of mainly conventional mines. It is becoming a full production reality at a number of key operations, both surface and underground. And if anything the market pressures, particularly in the form of cost scrutiny, are driving progress at a faster rate than ever before. But automation also brings unique safety and planning challenges, that are now also being addressed and considered. A Multi machine capability Atlas Copco states that: “by enabling the strength of a common control system on our new generation mine equipment we can enable customer value with smart functions and features on a large range of mine equipment.” The mechanisation era has been followed by the computerised or automated area for mining that has been around a couple of decades; and several improvements have been implemented thanks to on board computers and network based electrical systems. Oscar Lundhede – Atlas Copco Product Manager Underground Automation explained in a recent presentation the next generation impetus: “The operator has got help to control the equipment in the most efficient way and some operating tasks and routines have also been fully automated. Even the service and maintenance have improved helping the operator and technicians to solve problems and detect errors faster and more 00 International Mining | OCTOBER 2014 precise. But what about the control of the machine, isn’t it still one operator for one machine?” Since 2012 the Atlas Copco Simba Multi Machine control system has been available for remote control production drilling applications and has been in operation in LKAB in Sweden. Together with ABC Total and the new generation Simba the operator can supervise up to six production drill rigs. But now thanks to the common control system the same function in 2014 is now available for Scooptram LHDs. Atlas Copco started with teleremote functions on drill rigs in the 1990s in collaboration with LKAB in Sweden. It was a PLC based system with different supplier of the hardware and software. The Kiruna mine was working on wireless underground communication (WLAN) and Malmberget was using fixed cables connecting each rig. The Simba W469 or BK rig was controlled from a cabin in a close remote location from the rigs. Atlas Copco has for several years, been working on automated functions for repetitive routines. This is to increase the safety and working conditions but also to increase productivity. In 1998, Atlas Copco introduced the Rig Control System (RCS) to the market. The RCS made the equipment easier to use and made it possible to add different type of automation solutions, such as ABC Basic, ABC Regular & ABC Total. These functions assist the operator to control the drill rig with higher precision that Using Devex SmartMine UG, operators input the data from the onboard computer, which sends the information to the Operational Control Centre leads to increased productivity. Still today Atlas Copco drill rigs have the most comprehensive automation package on the market with additional proven functions such as Underground Manager, Measure While Drilling, Rig Remote Access, and Drill Plan Generator. The company recently won an International Design Award (IDA) for the RCS 5.0 rig control system for Boomer underground drill rigs. In 2013, the same product also won a design award from IDA. When it comes to the underground loaders and trucks there have been a number of steps towards automation for several years including vehicle monitoring systems, load weighing systems and several remote control systems. In 2005 Atlas Copco released a line-of-sight radio remote control for Atlas Copco loaders, the Scooptram RRC. The remote control was the first automation product developed for the Atlas Copco loaders. The company states: “The product has been a success when it comes to user friendliness, durability, cost efficiency and easy to support, and it is today operational in more than 30 countries world-wide.” The first RCS loader to be launched was the 14 t loader, Scooptram ST14 with RCS, introduced in 2006. This has then been followed by a 7 t loader (ST7), an 18 t loader (ST18) and a
