以某矿综采三机设备即采煤机、液压支架、刮板输送机为例，通过对综采工艺的理论研究确立综采三机在采煤过程中的联动关系，提出了三机联动控制系统解决方案。系统根据采煤机牵引位置和方向以及预定的联动规则控制液压支架动作，使其跟随采煤机完成收伸护帮板、移架及推溜操作。“,”Taking a fully mechanized mining three machine equipment that coal winning machine , hydraulic support,scraper conveyor as an example,According to the theoretical study of fully mechanized mining technology to Establish mechanized mining three machines linkage relationships in the mining process, and proposed three machine linkage control system solutions. The system according to the position and direction of the coal mining machine and the predetermined movement rules to control hydraulic support’s action, Make hydraulic support following the coal winning machine complete close and stretch the help guard plate、move the hydraulic support and push the scraper conveyor.
