摘要:
坑道智能化钻探的显著特征在于智能钻具的研发与应用和钻探数据的获取与分析，但现阶段我国煤矿坑道智能化钻探的研究基础较为薄弱，坑道智能化钻探缺乏科学化、精细化的技术手段，且缺乏系统性发展框架。针对该问题，阐述了我国煤矿坑道智能化钻探技术研究现状，从自动化钻机、导向钻进技术、孔内多参数获取、智能分析决策等方面总结了煤矿坑道智能化钻探发展成果与不足；在此基础上提出了煤矿坑道智能化钻探技术发展框架，指出应围绕精准导向系统、数据测量系统、数据传输系统、智能决策系统和自动控制系统，打造从孔底到孔口、从井下到地面的一体化坑道智能化钻探平台，构建“参数测量-智能决策-控制执行”坑道钻进过程闭环控制系统：通过数据传输系统将孔底随钻测量参数实时传输至地面远程数据支持中心，采用人工智能算法对地质参数、几何参数和工程参数进行协同分析，并实时更新三维可视化地质模型，制定钻进工艺参数和钻孔轨迹智能调控策略，控制井下智能钻机工作。
Abstract:
Development and application of intelligent drilling tool and acquisition and analysis of drilling data are outstanding characteristics of intelligent underground drilling. However,research foundation of intelligent underground drilling in China's coal mine is weaker at the present stage, and scientific and elaborate technical means of intelligent underground drilling is lacked as well as systematic development framework. For the above problems, the research status of intelligent underground drilling technology in China's coal mine is expounded, and development achievements and shortcomings of intelligent coal mine underground drilling are summarized from the aspects of automatic drilling rig, guided drilling technology, multi-parameter acquisition in hole, intelligent analysis and decision-making, etc. On this basis, the development framework of intelligent coal mine underground drilling technology is proposed, and it is pointed out that the development framework should be focused on accurate guidance system, data measurement system, data transmission system, intelligent decision-making system and automatic control system, so as to create an integrated and intelligent underground drilling platform from hole bottom to hole ostiole and from underground to ground. Meanwhile, a closed-loop control system of parameter measurement, intelligent decision-making and controlling execution for underground drilling process should be constructed, which real-timely transmits measurement parameters while drilling in hole bottom to remote ground data support center through data transmission system, cooperatively analyzes geological parameters, geometrical parameters and engineering parameters by use of artificial intelligence algorithms, and updates 3D visual geological model real-timely, so as to draw up intelligent adjustment and control strategies of drilling technology parameters and borehole trajectory for controlling intelligent underground drilling rig to run.
