摘要
针对煤矿综采工作面液压支架传统控制方式存在安全性能差、控制精度较低、压力波动较大等问题,研究了煤矿综采工作面液压支架协同控制安全运维技术,结合智能传感检测技术和耦合控制机理,提出了一种液压支架自适应协同控制安全运维系统,采集和分析液压支架的姿态和位置全过程数据,以实现液压支架之间的协同控制。通过在某煤矿井下1107综采工作面现场安装和应用后得出液压支架协同控制技术能根据围岩性质自动协调控制液压支架状态,集中控制采集的现场数据,从而实现对液压支架的协同控制,控制系统可自动调整千斤顶,控制误差不超过3.5%,取得了满意的实验结果。
Aiming at the problems of poor safety performance,low control accuracy,and large pressure fluctuations in the traditional control method of hydraulic supports in coal mine fully mechanized mining face,this paper studies the collaborative control and safety operation and maintenance technology of hydraulic supports in coal mine fully mechanized mining face.Combining intelligent sensing detection technology and coupling control mechanism,a hydraulic support adaptive collaborative control and safety operation and maintenance system is proposed,which collects and analyzes the entire process data of the posture and position of hydraulic supports to achieve collaborative control between hydraulic supports.After on-site installation and application in the 1107 fully mechanized mining face of a certain coal mine,it was found that the hydraulic support collaborative control technology can automatically coordinate and control the status of the hydraulic support according to the properties of the surrounding rock,centrally control the collected on-site data,and achieve collaborative control of the hydraulic support.The control system can automatically adjust the jack,and the control error does not exceed 3.5%,achieving satisfactory experimental results.
