    针对煤矿智能化快速发展,煤矿掘进面临新的机遇和挑战,笔者对我国煤矿快速掘进20 a的发展进行全面综述,以期理清掘进工艺、关键工序的技术及装备、成套装备的发展脉络及趋势,以便更好地推动掘进智能化的高速健康发展。在掘进工艺方面,双巷掘进开辟了截割、支护在不同巷道同时作业的新途径;掘锚同步工艺,时间−空间多维同步快速掘进工艺打破了先掘后支、及时全部支护的传统,创立了掘锚同步、迎头必要支护与多维空间永久支护动态匹配的分区支护方法。在掘进装备方面,形成了以纵轴、全宽横轴截割滚筒为主,全断面截割滚筒为辅的截割滚筒结构形式,并且在高功率密度减速器及整机设计理念不断突破的基础上,成功研制纵轴截割功率达315 kW、全宽横轴截割功率达560 kW的系列高效截割系统。在锚护装备方面,由传统的单体锚杆钻机发展出锚杆钻机、一键操作流程化钻机、钻机集群等,在有限空间内钻机的数量和作业安全性得到大幅提升,作业流程得到大幅简化,锚孔识别、锚护路径自动规划等智能化技术已进入工业性试验阶段。柔性运输系统的发明解决了掘进面短距离高效转载难题。在成套装备配置上,形成了以连续采煤机、掘锚一体机、掘锚机(掘进机+机载锚杆钻机)、煤矿全断面掘进机为龙头的四大类快速掘进系统,在四大快速掘进系统下,又分别形成了不同的作业线, 实现了对不同地质条件巷道快速掘进的全覆盖。掘进工程系统层级上实现了具有成套装备的远程控制、集中控制、视频监测、闭锁联动、人员接近预警等智能化功能。回顾快速掘进的发展历程,提出完善时间−空间多维同步快速掘进理论、以智能掘进搜集透明地质的基础大数据、加强掘进巷道辅助作业工艺及设备研究、加强装备的智能化核心技术研发等智能掘进的发展方向。

  • Abstract

    Coal mine excavation faces some new opportunities and challenges under the rapid development of intelligent coal mines. In order to promote intelligent tunneling rapidly and healthily, a comprehensive review about the 20 years development of rapid coal mine tunning in China was conducted, with a view to clarify the development context and trends of tunneling technology, key process technologies and equipment, and integrated equipment in tunneling system. In terms of tunneling technology, the double-roadway excavation has opened up a new way for excavation and anchor in adjacent roadways at the same time. The excavation and anchor synchronization process, and the time-space multi-dimensional synchronous rapid tunneling process break the tradition which contains cutting first, then supporting, and in-time fully supporting, and thus establishes a new excavation process based on cutting and supporting at the same time, the dynamic matching of head face necessary support and permanent support in multi-dimensional space. In terms of key core technologies, the cutting head has gone through three styles: longitudinal axis style, horizontal axis style with full width and full-face style. On the basis of continuous breakthroughs in the high-power density reducer and design concept of whole machine, a series of high-efficiency cutting systems with longitudinal cutting power up to 315 kW and full-width transverse cutting power up to 560 kW has been successfully developed. Supporting operation is developed from the traditional single anchor drilling rig to machine-arm mounted, machine mounted anchor drilling rig, anchor drilling rig with one-key operation, and anchor drilling rig cluster, etc. The number of drilling rigs and operation safety in limited space have been greatly improved, and the operation process has been greatly simplified. Intelligent technologies such as anchor hole identification and automatic planning of anchor path have entered the industrial test stage. The invention of the flexible transport system solves the efficient transfer problem of coal in short distances in tunnel. In terms of integrated equipment configuration, four types of fast excavation modes led by continuous mining machine, bolter miner, roadheader and TBM have been formed. Many different operation lines have been formed under the four rapid excavation modes, that form a full coverage of rapid excavation under various geological conditions. At the system level, intelligent functions such as remote control, centralized control, video monitoring, locking linkage, and personnel approach warning have been realized. Based on the development process of rapid tunneling, the development directions of intelligent tunneling are finally proposed, which contains the theory improvement of multi-dimensional synchronous rapid tunneling in time and space, the data collection for transparent geology based on intelligent excavation, the research of auxiliary operation technology and equipment of tunneling roadway, and the research and development of equipment intelligent technology.
