一种采煤控制系统、采煤系统和液压支架
摘要：
本发明提出一种采煤控制系统、采煤系统和液压支架，采煤控制系统包括：安装在一个液压支架上的至少一个发射接收天线、安装在液压支架上的信号采集站和安装在采煤装置上的数据处理主站；所述信号采集站控制所述发射接收天线发射电磁波信号，电磁波信号在煤岩界面产生信号回波，所述发射接收天线接收信号回波并将信号回波传送给所述信号采集站，所述信号采集站根据信号回波计算得到单点煤岩信息并将所述单点煤岩信息发送给数据处理主站，所述数据处理主站根据至少一个所述单点煤岩信息得到煤岩分界面信息，并根据所述煤岩分界面信息控制所述采煤装置。本发明解决了人工打眼探测煤岩界面的方式带来的测量不准确、劳动强度大和效率低等问题。
摘要（英）：

The invention provides a coal mining control system, a coal mining system and a hydraulic support. The coal mining control system comprises: at least one transmitting and receiving antenna mounted ona hydraulic support, a signal acquisition station mounted on the hydraulic support, and a data processing main station mounted on the coal mining device; the signal acquisition station controls the transmitting and receiving antenna to emit an electromagnetic wave signal, the electromagnetic wave signal generates a signal echo at a coal rock interface, and the transmitting and receiving antenna receives the signal echo and transmits the signal echo to the signal acquisition station; the signal acquisition station calculates single point coal rock information according to the signal echo and transmits the single point coal rock information to the data processing main station; and the data processing main station obtains coal rock interface information according to at least one of the singlepoint coal rock information, and controls the coal mining device according to the coal rock interface information. The problems of inaccurate measurement, large labor intensity and low efficiency dueto the method of detecting the coal rock interface through artificial hole drilling can be solved.
