(10)Development of spray systems for frictional ignition protection when cutting minerals in an explosive atmosphere and for effective dust control

摘要

This manuscript will provide an overview of the development of water spray systems and their application experiences. It will look at various types such as Pick Back Flush Sprays (PBF Sprays) and Pick Front Flush Sprays (PFF Sprays), Rotary air curtain (RAC), Water-Air mist sprays and Ejector sprays (in German: Ejektor-Bediisung or EB). Applications from Australia, China, Russia, Great Britain, the Czech Republic and Germany are considered with regards to function, effectiveness and water consumption.
