自实现机械化采矿后，进一步实现智能化以解放矿工就成为世界采矿界的科研目标。 在回顾智能化采煤技术发展历程的基础上，对我国智能化采煤技术研究与应用现状进行系统回顾分析，并对未来待突破的关键技术进行展望。 

首先，介绍了智能化采矿技术的发展历程，概述了动力化、自动化、信息化等发展阶段对采煤工作面的要求，进而提出了智能化采煤工作面的基本要求；其次，从科研计划研究、国内学术论文发表、相关专利授权以及国内煤矿实践探索等方面，对我国智能化采煤技术的创新现状进行分析与总结。

结果显示我国从“十一五” 起就开始重视智能化采煤技术的研究，通过10余年的大力发展，批准了近10个与采煤智能化技术有关的国家重点研发计划项目，同时产生一大批学术论文和授权专利，这些创新成果形成了薄煤层、中厚煤层、大采高与超大采高、特厚煤层等4种智能化采煤基本模式，并建成了近200处不同层次的智能化采煤工作面；再次，从采煤机、液压支架、刮板输送机、带式输送机、巷道集中监控技术等5个方面，归纳了在初级智能化采煤工作面上已成熟应用的35项智能控制技术；最后，针对复杂条件下的智能化采煤工作面技术难题，提出了有待进一步研究突破的精准定位、煤岩识别、智能支护、自主纠偏和智能煤流感控等5项智能化采煤关键技术，并给出相应的技术突破思路。

通过调研分析，认为我国现阶段的智能化采煤装备技术总体已达到自主化、成套化、实用化的国际先进水平，未来还需进一步提高智采工作面的自主能力和适用范围。

Since the realization of mechanized mining, further realization of intelligence toliberate miners has become the unremitting pursuit of the world’s mining industry.On the basis of reviewing the development process of intelligent coal mining technologies, the research and application status of intelligent coal mining technologies as well as the potential key technologies in China were systematically reviewed and analyzed.Firstly, it introduced the development process of intelligent mining technology, outlined the requirements of coal mining face from the development stages of motorization, automation and informationization, and then put forward the basic requirements of intelligent coal mining face.Then,the innovation status of intelligent coal mining technology in China were analyzed and summarized from four aspects: scientific research plan, domestic academic paper publication, relevant patent authorization and domestic coal mine practice exploration.The results show that China has begun to attach importance to intelligence since the 11th five year plan.Through more than ten years of vigorous development, nearly 10 national key research and development projects related to intelligent coal mining technology have been approved.At the same time, a large number of academic papers and authorized patents have been produced.These innovative achievements have formed four basic models of smart coal mining, including thin coal seam, medium thick coal seam, large mining height, super large mining height and extra thick coal seam, and have built nearly 200 intelligent coal mining working faces at different levels.On this basis, this paper sums up 35 smart control technologies that have been mature and applied in primary smart coal faces based on shearer, hydraulic support, scraper conveyor, belt conveyor and centralized monitoring.Finally, aiming at the technical problems of intelligen coal mining face under complex conditions, five key technologies of intelligent coal mining which need to be further studied in the future are proposed and corresponding technological breakthrough ideas are given.These include precise positioning technology, coal-rock interface identification technology, surrounding rock adaptive support technology, autonomous correction technology and intelligent coal traffic sensing technology.Based on these investigations and analysis, it is concluded that the smart coal mining equipment technologies in China at present have reached an international advanced level of autonomy, complete sets and practicality.However, the autonomy ability and of application scope of the smart coal mining working face need to be further improved in the future.
