目前国内智能化开采技术与装备迎来了重要的历史发展机遇期，国内已累计建成200百多个以“可视化远程干预智能化开采技术”为主的自动化工作面。通过分析智能开采应用现状，指出由于煤矿工作面开采条件的多样性与复杂性，智能开采发展必然是分阶段、逐步实现，同时智能开采常态化应用受限于综采装备与控制元件等基础可靠性的提高及从业人员素质与能力的提高，因此智能开采发展与应用是一个长期的过程；基于现阶段国内自动化工作面的应用技术现状，从系统感知技术能力与特征的角度将智能开采发展阶段划划分为4个阶段，并指出现阶段国内总体应用水平还处于智能开采的初级阶段，部分矿井正在试验第二、三阶段的关键技术，离智能开采技术的理想目标还有很长的路要走。并围绕智能开采第二阶段的关键技术，重点阐述了基于装备主体结构件机械模型的液压支架与采煤机姿态感知技术、基于国产惯性组合导航装置的刮板输送机弯曲度检测技术、采煤机行走轨迹、开采刀识别以及工作面自动校直等技术原理与实践情况。通过工业性实践验证了液压支架与采煤机姿态感知技术以及工作面矫直方法等理论与工程的可行性，为工作面的液压支架防倾斜、防咬架、快速移架，截割面的开采规划与采煤机滚筒姿态调整、煤机干涉预警以及刮板输送机直线度调整等功能的具体实施提供了技术支撑。

At present,China’s intelligent mining technology and equipment have ushered in an important period of historical development opportunities, and more than 200 automated working faces have been built in China, based on the“visual remote intervention intelligent mining technology”.By analyzing the status of the application of intelligent mining, it is pointed out that due to the diversity and complexity of mining conditions in the coal mining face, the development of intelligent mining must be realized in stages.At the same time, the normal application of intelligent mining is limited by the improvement of the basic reliability of comprehensive mining equipment and control elements and the development of smart mining and the improvement of the quality and ability of employees, so the development and application of intelligent mining is a long-term process; based on the current status of the application technology of the working face, the development stage of intelligent mining from the perspective of system perception of technical capabilities and characteristics can be divided into four stages, and it is pointed out that the current stage is still in the initial stage of intelligent mining.Some mines are testing key technologies in the second and the third stage, and there is still a long way to go before the ideal goal of intelligent mining technology.Focusing on the key technologies of the second stage of intelligent mining, this paper focus on the hydraulic support and shearer attitude sensing technology based on the mechanical model of the main structural parts of the equipment, the bending detection technology of the scraper conveyor based on the domestic inertial integrated navigation device, the technical principles and practice of the machine’s walking tracks, mining cutters identification and automatic straightening of the working face.The theoretical and engineering feasibility of hydraulic support and shearer attitude sensing technology and working face straightening method were verified through industrial practice.It provid technical supports for the concrete implementation of the hydraulic support of the working face, such as anti-tilt, anti-bite frame, quick-moving frame, mining plan of the cutting face, posture adjustment of the shearer drum, early warning of coal machine interference, and straightness adjustment of the scraper conveyor.
