[摘    要]无人采煤工作面系统是煤炭综采成套装备的重要组成部分,由于煤矿综采工作面在煤矿生产过程中涉及的设备较多,而且工作环境恶劣,是一种工作复杂的操作系统。无人工作面的采煤机作业,利用先进技术全程智能化操控,提升采煤安全率的同时,节约了劳动成本,是一种先进高效的回采技术。在采煤过程中矿井通信十分重要,矿井下的各类指标数据、实际情况等都要进行井上井下的双向输出。文章针对无人工作面的采煤机智能控制的关键技术展开讨论,具体分析采煤机智能控制技术在无人工作面的相关应用,以供参考。

Research on Intelligent Control Technology of Shearer in Unmanned Face

He Xin-xing

[Abstract]Coal is a non-renewable resource, and coal reserves are drastically reduced. For some areas with thin coal seams or coal areas where manual mining is difficult, it is necessary to use coal mining machines with unmanned working faces. The unmanned coal mining face system is an important part of the complete set of coal mining equipment. Because the coal mining face involves more equipment in the coal production process and the working environment is harsh, it is a complex operating system. Therefore, the intelligent control system for fully mechanized coal mining face has always been a hot topic that people have studied vigorously. The operation of the coal shearer on the unmanned working face uses advanced technology to intelligently control the whole process, which improves the safety rate of coal mining while saving labor costs. It is an advanced and efficient mining technology. Mine communication is very important in the process of coal mining. All kinds of index data and actual conditions in the mine must be output in both directions. The article mainly discusses the key technology of the intelligent control of the shearer in the unmanned face, and specifically analyzes the relevant application of the intelligent control technology of the shearer in the unmanned face for reference.

1.1 采煤机自动定位技术

一般来说,采煤机是一种高集成度的、井下综采无人工作面割煤、装煤的主导设备。采煤机主要沿着刮板输送机轨道往复式割煤,液压支架配合相关的支护工作。为了實现综采工作面远程自动控制,必须精准定位采煤机的动态位置。因此,采煤机自动定位技术是实现煤矿生产设备自动化的关键技术。由于煤矿综采工作面的工况极为复杂且空间封闭,所以,采煤机定位定姿方法也有很多。其中红外定位法是由采煤机上的红外发射装置发出信号,再由液压支架上的接收装置接收相关的信号,但红外信号极易受粉尘影响,存在一定的定位盲区,因此有一定的使用局限[1]。……
