Low-profile Face Drilling Rig is Built for Heavy Tramming
Atlas Copco's newest single-boom face drilling rig is designed for development and production drilling in low- to medium-height mines, including applications with exten- sive tramming. With a machine height of 5.9 ft (1.8 m), the Boomer M1 L is sized for room-and-pillar mines with back heights from 7.2 to 8.2 ft (2.2 to 2.5 m). The rig's carrier features heavy-duty axles and a rein- forced articulation section as well as over- sized wheels compared with similar rigs in the range. According to the company, com- ponents and systems from existing drill rigs such as the Boomer S1 L and the Boomer M2 D were incorporated into the design of the Boomer M1 L to respond to customer demand for a more robust single-boom face drilling rig for low height applications. The Boomer M1 L also features a fully enclosed, air-conditioned cabin, and an ergonomic control panel, contributing to operator safety and comfort. Power is pro- vided by a Deutz 80-kW (107-hp) Tier 3 engine. Additional design highlights include an improved flexible boom, simple controls (Direct Control System 2), as well as a choice of COP 1638 or COP 1838 rock drills. The rig is designed to be easy to service, with easily accessible service points behind protective hatches. Atlas Copco said a prototype of the Boomer M1 L was successfully tested by the Polish mining company KGHM which has since placed orders for several units.

Haulage Scheduling Software Gets 64-Bit Performance Boost Mintec has released a new version of MineSight Schedule Optimizer. Chief among the host of enhancements in Ver- sion 4.0 is its seamless integration with MineSight Haulage, plus an upgrade to 64- bit technology. Using Canvas for flowsheet design and a new graphic user interface, Version 4.0 now takes advantage of haulage data prepared by Mintec's MSHaulage software. It imports destina- tions (lift, subzone, ton/volume capacities, filling sequence) directly and automatical- ly from MineSight Planning Database, plus equipment set and parameters (truck, shovel and delay time), cycle time, cycle distance, cycle path and fuel consumption.
By dragging and dropping, Canvas allows users to graphically and intuitively define mining areas, destinations, and material routing. The improved GUI allows most panels to be dockable, allowing users to open them side by side. Schedule Optimizer now generates schedules that satisfy quality, quantity and blending requirements, as well as satisfying truck and shovel hour constraints. Because of their relationship, material routing sched- uling and equipment scheduling are con- ducted simultaneously. Version 4.0 calcu- lates truck hours based on the cycle time from each cut to each possible destination. It calculates shovel hours based on the load time and the number of trips for send- ing materials in each cut to each destina-
