Study on key technology of coal mine intelligent continuous transportation

In view of the current situation that the coal flow system has the reverse coal flow starting and the non optimal operation state of full speed all the time, resulting in the invalid consumption of electric energy and the invalid wear of the transmission parts of the coal flow system, in order to improve the running efficiency of coal flow, the authors discusse the key technology of mine intelligent continuous transportation, including four parts:coal quantity detection technology, intelligent control strategy,intelligent monitoring and early warning and coal flow system big data remote monitoring cloud platform.Through video image analysis and processing, coal quantity detection technology can detect the width, sectional area or volume of coal on the coal flow conveying line, so as to calculate the instantaneous coal quantity, which can be used as the data source of intelligent speed regulation of coal flow system.Through improving the control and operation process of coal flow system, namely, self-adaptive start-up control from the upstream to downstream or inversely, self-adaptive speed regulation according to coal quantity and multi-level equipment collaborative control, the operating efficiency and intelligence level of coal flow system are improved, energy saving and consumption reduction are achieved, and the service life of equipment is prolonged.The Inspection robot which equipped with HD camera device, thermal imager and a variety of harmful gas sensors, can perform underground inspection along coal flow system, replace manual inspection, and realize intelligent monitoring and early warning.Through the collection, storage, analysis and display of the running state data of the coal flow system, coal flow system big data remote monitoring cloud platform solves the problems,such as time consuming and lag in troubleshooting of the coal flow system, and realizes the automation, digitization and remote real-time monitoring of the coal flow system production process.
