As China moves to improve its coal mine safety record, it is investing in new, large-scale mining operations with modern equipment, while also improving the safety and productivity of medium-sized operations. Noting this trend, U.K.-based equipment supplier RMI Pressure Systems has launched a range of high-pressure pump stations designed to provide a cost-effective pumping system aimed at powering roof support systems commonly used in the mid-sized mines.
RMI noted that it has been involved with the Chinese coal mining industry for 30 years and has installed high-pressure pumping systems in more than 10 pro-vinces across China. Its new Streamline range of pump stations has been developed specifically for the industry's second-tier mines, using a standard product offering. This approach, according to RMI, enables it to increase the scale of production and reduce manufacturing costs for the range without affecting safety and reliability factors.
Based around its S range of pumps, RMI has developed six models in the Streamline range; three for emulsion systems and three for water systems. The emulsion systems are supplied with three S375 pumps, which operate as duty, assist and standby and are supplied by two tanks. The water systems operate with two S300 pumps, on a duty/standby arrangement, and come with one supply tank. Both systems are controlled by the same technology found on the company's current range of larger pumping stations.
