4 E&MJ • JUNE 2018 COMPANY PROFILE-PAID ADVERTISEMENT Regulations are having a significant impact on productivity in the mining industry. There are options that can help a mine increase production while at the same time adhering to drill and blast regulations, addressing sound and vibration abatement and reducing dust to minimize the effect on air quality. One solution is the Vermeer T1255III Terrain Leveler SEM. The Terrain Leveler SEM features an optional dust suppression system, GPS steering and grade control, as well as the ability to cut up to an 80-degree high-wall with the single-sided direct drive attachment and up to a 90-degree high-wall with the chain drive attachment. This technology is ideal for use in surface mine applications — especially those faced with drill and blast restrictions or urban encroachment. The ad- vantages of the Vermeer technology are numerous: • Access areas of surface mines where drilling and blasting cannot be done because of physical or permit limitations. • See a reduction in noise, dust and vibration compared to drill and blast. • Produce a smaller, more consistent particle size, helping to eliminate the primary crusher step. • Use the Terrain Leveler SEM for haul road construction and maintenance. How It Works The Terrain Leveler SEM features a patented tilt-head milling attachment with top-down cutting action that can dig up to 21 inches (53.3 cm) deep and 144 inches (365.8 cm) wide in a single pass. As the unit travels forward and the drum rotates, the teeth on top of the drum advance over the top of the mineral surface. Operators can also control material sizing by increasing or decreasing the tooth penetration to produce an 8-inch (20.3 cm) minus product. Uniform product size also allows more efficient settings on second- ary and tertiary crushing systems. Enhanced Efficiency and Dust Suppression The Vermeer T1255III direct drive Terrain Leveler SEM features a fully hy- drostatic motor mounted to the side of the cutting head providing direct drive power to the cutting drum. The direct drive drum design delivers more horse- power to the cutting drum, resulting in enhanced efficiency when working in hard rock conditions. In addition, the single-sided direct drive drum allows the quarry operator to cut an 80-degree high-wall providing slope stability that is desired in high-wall mining applications. Vermeer also offers a chain drive drum which allows the quarry operator to cut a 90-degree high wall, and is also designed to work in hard rock conditions. On many mine sites, dust is a challenge due to urban encroachment and air quality concerns. An optional dust suppression system on the Vermeer Ter- rain Leveler SEM features an enclosed cutting head with two large vacuums pulling dust from the enclosed cutting head into baghouses. The collected dust is dropped beneath the machine, helping to reduce the amount of dust entering the air. This also diminishes the need to source water to control dust during the mining process. GPS Technology and Autonomous Control The T1255III Terrain Leveler SEM also features an optional GPS technology that can also be used to create a mine-by-line plan. A mine plan can be up- loaded to the GPS system and the machine will automatically cut to the plan. A patented tilt cutting head tied to GPS technology allows the operator to control the cutting head depth and pitch. This feature allows the operator to cut to the mine plan — producing a flat, almost road-smooth surface; a grade for drainage; or a sloped haul road. The technology also eliminates rapid changes in cutting depth, which can impact productivity, and can provide more precision cutting than an operator-controlled system. Performance Monitoring The T1255III is equipped with Vermeer SmartTEC control software that as- sists operators with adjustments to machine operation to help maximize ma- chine performance. The SmartTEC system displays the status of the many critical elements of machine performance, with prompts providing visual cues to the operator for recommended control adjustment. The software also monitors and records various machine operation attributes for future analysis by the machine owner or fleet manager. Operator Safety The cab features an operator presence system that disengages the ground drive and cutting attachment if the operator leaves the seat. The machines are available with a rollover protective module (ROPM) and a falling object protective structure (FOPS) for working near a high pit wall. The machine's low center of gravity helps maintain machine stability.
