BAUMA 2013 measurement technology and developed two high-performance CH4 tools for analysis and control. The analysis tool provides a program for optimized production planning that takes account of CH4-related stoppages, cutting depths and shearer travel speeds. This planning instrument is supported by a control tool that can deliver production below the CH4 shut-down limit by timely intervention in the machine control system during the active winning phase. Both tools combine to reduce on-face stoppages by keeping below the CH4 shut-down threshold, thereby helping maximize daily output. The EXR tracks explosives inventories and blasting accessories use an enterprise system. The program is an integral part of the SAP MM module and is designed to log each and every material movement so that each individual unit can be stored in a lifecycle tracking system. The company also demonstrated the latest control room technology, which is now being used to manage high-performance coal mine operations. Xylem Brings Back BIBO Xylem has launched a new series of submersible dewatering pumps modeled on www.e-mj.com its iconic and hugely popular Flygt BIBO pump. The new range incorporates several proven design features taken from the original dewatering pump, as well as innovative enhancements that give the new pumps unmatched wear resistance and uptime capability. Xylem's Flygt BIBO series has been specifically designed for the toughest dewatering environments. "We are delighted to unveil the new Flygt BIBO," said Daniel Westin, product manager at Xylem. "The reliability and capability of the original Flygt BIBO dewatering pump is renowned within the industry and set the standard for submersible dewatering when it was first launched in the 1960s. More than 1 million of the original pumps have been sold since it was first brought to market. This celebrated design forms the core of this new generation of Flygt BIBO pumps that now include the most advanced pumping technology, bringing the best in dewatering pump capability to the market. "Xylem's new Flygt BIBO includes several innovations such as our DuraSpin hydraulic system for unmatched wear resistance, a new plug-in seal and a sin- gle impeller-adjustment screw. All of these innovations work together to deliver our customers a pump with high uptime capability and a limited and lowcost service requirement," Westin said. Xylem's new Flygt BIBO is available in four models, 2830, 2840, 2860 and 2870, capable of handling flows of up to 100 l/s (1,600 gpm), heads up to 80 m (300 ft) and solids up to 12 mm in diameter. Available with power ranges from 3.7 to 18 kW and (6 to 27 hp), this series of pumps is engineered for professional use in the harshest of environments. Water-powered Drilling For 20 years Swedish iron ore miner LKAB has used water-powered technology to improve underground production drilling while at the same time reducing energy consumption. Its production blastholes are now twice as long and each blast provides eight times more ore. Now Wassara is offering the rest of the world the same opportunity. In the 1980s, LKAB faced a great challenge, scaling up its production. To achieve some high goals, the company needed more efficient mining, reducing JUNE 2013 • E&MJ 103
