Abstract
A solid-filling coal mining feeding and conveying monitoring system, suitable for monitoring of a vertical feeding and conveying system in underground mine solid-filling mining. The monitoring system mainly consists of an industrial control computer, a PLC control box, an operating platform, a liquid crystal display, a color four-picture divider, two video optical receivers and loudspeakers, four cameras, uphole electronic belt scales, downhole electronic belt scales, a radar level meter, a coal level sensor, a vibration sensor, and various matching junction boxes and cables, the components being installed in positions such as a material field, a control room, upper and lower openings of a storage silo, and a gangue transportation lane. The system implements four main functions of a solid-filling material transportation and feeding process, the four main functions being status monitoring, a full silo alarm, centralized control, and recording and querying. The monitoring content of the system is comprehensive; operation of the system is simple; and the system is safe and reliable.
