大采高综放开采引起围岩的强扰动,造成矿压显现明显对支护设备和人员安全造成危害,金鸡滩煤矿通过在液压支架的相关位置上布置压力传感器和倾角传感器,将相关数据传输到监测系统平台,做到对液压支架的实时监测预警;非直线排布的运输机加大了齿轨的磨损,损伤支架与运输机连接部位造成安全隐患;结合井下实际情况对运输机、采煤机等设备进行惯性导航直线度控制,使工作人员可以随时掌握设备的位置、速度、姿态和方位等信息;为了更好地控制放顶煤冒落的过程中后部液压支架的开启和关闭时间,开发了基于电液控制的时序化放煤工艺及自动化放煤控制系统,实现了对放顶煤冒落的实时控制,建设了动态感知、自动分析、智能处理的高效、节能、安全、少人的智能化工作面。

The strong disturbance of surrounding rock caused by large mining height fully mechanized mining results in obvious mine pressure behavior, which poses a threat to support devices and personnel safety. Jinjitan Coal Mine by arranging pressure sensors and dip angle sensors at relevant positions of hydraulic supports to transmit relevant data to the monitoring system platform to achieve real-time monitoring and early warning of hydraulic supports; The non-linear arrangement of transport aircraft increases the wear of the gear rail, damaging the connection part between the bracket and the transport aircraft, causing safety hidden dangers; Combined with the actual downhole situation, inertial navigation straightness control is carried out on devices such as transport aircrafts, coal cutters and so on, so that workers can grasp information such as the position, speed, attitude, orientation and others of the device at any time; In order to better control the opening and closing time of the rear part hydraulic support during the process of top coal caving falling, a time sequential coal caving technique and automated coal caving control system based on electro-hydraulic control are developed. Real time control of top coal caving falling is achieved, and an efficient, energy-saving, safe, and unmanned intelligent working face with dynamic perception, automatic analysis, and intelligent processing is constructed.
