SAFETY
Left: The Trimax S range of pumps from RMI have been used across the world in mining operations
Below: Modern longwall mining techniques require a roof support system that maintains a safe working area while moving with the shearer and allowing a controlled collapse of the roof
T e roof support system consists of a series of individual shield units that use hydraulic rams to hold the overhead shield plates in place. All of the units are connected together and powered by a high-pressure hydraulic pump that provides the power to hold thousands of tonnes of rock in place while the coal face is mined. RMI Pressure Systems is an expert in high-pressure pumping systems. With particular expertise within the mining industry, both above and below ground, many of the company’s most popular products include certifi cations and approvals from some of the world’s leading mining organisations. T e Trimax S range of pumps has been used across the world in many of the largest mining operations. Constructed from high quality materials, and manufactured to exacting tolerances, the S range is
capable of producing 517 l/min at pressures up to 600 Bar.
RMI also has a policy of continuous
development of energy-effi cient products, which has led to the introduction of the ODIN (On Demand Intelligence) control system. It uses a range of data supplied from
equipment used in the process of continuous longwall mining and uses it to calculate the changes in demand for hydraulic fl uid before they occur. In this way ODIN can modulate the pump speed and change the fl ow and pressure characteristics to meet demand in the most responsive way possible.
RELIABILITY AS STANDARD W
hen asked what inspires his fi rm’s work, RMI's Mike Sherman explains that being dedicated to improving safety is not a recent thing for the company. “We’ve been helping to maintain mine safety for many years,” he begins. “With the majority of applications in remote areas, with limited
access and where unplanned downtime is very expensive, reliability is an essential quality required of our equipment. “We have an enviable
reputation for designing effi cient and reliable equipment, which has been used across the world in the longwall mining industry for many years.”
