综放工作面煤矸自动识别系统设计及应用

提出了一种基于振动信号的综放工作面煤矸自动识别系统,介绍了系统结构及工作原理,重点阐述了煤矸识别设备的软、硬件设计方案及煤矸识别算法。该系统由煤矸识别设备依据煤与矸石跌落到液压支架上时的振动信号不同来辨识煤矸,液压支架电液控制器根据辨识结果控制液压支架动作。该系统在某煤矿进行了煤矸的可辨识性和自动放煤过程的可控性测试,并已应用于部分煤矿,效果较好。

Design of automatic identification system of coal and gangue for fully-mechanized coal caving working face and its application

An automatic identification system of coal and gangue for fullly-mechanized coal caving working face based on vibration signal was proposed,structure and working principle of the system were introduced and design schemes of software and hardware of coal and gangue identification device were expounded as well as identification algorithm.The coal and gangue identification device identifies coal and gangue according to different vibration signals of coal and gangue falling on hydraulic support.Electrohydraulic controller controls hydraulic support act according to identification result.The system has been tested with contents of identifiability of coal and gangue and controllability of automatic coal caving process in a mine and applied in some mines,which gets better effect.
