变频器作为一种成熟的高新技术产品，已经在神东公司的各主要生产环节中广泛应用，发挥着重要的作用。矿井的主运输系统在升级改造为变频驱动后，变频胶带机充分发挥了开机率高、可靠性高、故障率低、维护保养成本低等特点，同时也改变了其他驱动方式下胶带机带速不可调节的弊端。 本文针对神华神东煤炭集团公司某煤矿的主运输系统，结合矿井自动化系统和带式输送机驱动变频控制系统，研究煤矿生产的不均衡性，即矿井主运输系统煤量变化比较大等关键问题。在此基础上设计具有自动煤量识别和自动节能运行的控制系统，充分发挥变频主运输系统的高可靠性和安全节能运行。 自动煤量识别和自动节能运行的控制系统，采用模糊控制原理，建立总控制决策表，提高带式输送机的控制精度。 该控制系统在神东煤炭集团已经应用，根据目前来看完全能够满足现场运行的要求，实现自动节能运行，并在具备条件的多个矿井开始推广使用。本文的研究对目前国家提倡的节能减排具有良好的经济意义和社会意义。

The frequency converter is a proven product with high and new technology, which has been widely used in production operation and plays a more important role. After the primary transportation system has been updated with the frequency converter drive, the VFD conveyor has shown the unique characters, such as higher equipment availability, higher reliability, lower failure rate and lower maintenance cost, and discard the disadvantage of fixed speed on other non-VFD conveyor. Based on the primary transportation system in one coal mine of Shenhua Shendong Coal Corp. Ltd., this dissertation studied on the colliery automation control system and internal control system of the VFD conveyor, and the unevenly production of the coal mine, namely the amount of coal on the belt vary all the time during the whole production shift. Then engineered the new control software with self identifying the amount of coal on the belt and the belt conveyor could be operated under the automatic energy-saving mode, fully demonstrating the high reliability and safe energy-saving operation. The above mentioned control software, which based on the Fuzzy control theory with the work-outed decision-making chart, has improved the control accuracy of the VFD conveyor. The control system has been applied in the transportation system in Shendong Coal Cor. Group. Up to now, it has met the requirement of the daily operation with automatic energy-saving mode. And the control software will be utilized on other coal mine within Shendong Coal. This dissertation’s study has meaningful impact on social and economic aspects with regard to the national advocating on the energy-saving and emission-reducing.
