    针对黄陵矿区及条件类似工作面大采高智能化开采煤壁控制现状,尤其是在片帮预警、智能控制等方面的难题,考虑智能化开采和综合机械化开采的工艺区别,从工作面设计、工作面设备参数确定、护帮参数优化、传感器方案、控制方案等5个方面,在预防、发展、防护3个阶段进行考虑和设计智能化开采煤壁控制方案。优化了液压支架护帮机构及护帮控制方式,设计了护帮板精准控制工艺,建立了基于片帮影响因素的工作面煤壁片帮预警模型,提出采用视频监控、太赫兹扫描和人员定位技术,结合工作面设备集中控制系统的工作面片帮防护体系,形成了大采高智能化开采煤壁全过程精准控制技术。将片帮控制技术纳入工作面智能化开采控制系统,有效解决了智能化开采煤壁控制难题,支架工由5人操作减少为无人操作,1人巡视,在黄陵矿区二号井顺利实施了大采高智能化开采,工作面年产量达到600万t。

  • Abstract
    In view of the current situation of intelligent mining of coal wall in the Huangling Mining Area and similar working face, especially in early warning and intelligent control, considering the differences between the intelligent mining and the comprehensive mechanized mining process, the intelligent mining coal wall control scheme was designed based on three stages of prevention, development and protection and the aspects such as design, working surface equipment parameter determination, maintenance parameter optimization, sensor scheme and control scheme. The hydraulic support mechanism and the control method of the guard were optimized, and the face guard structure precision control technology was designed. Wall caving forwarding model was established, and the working face wall caving protection system was put forward combining video monitoring, Tera Hertz scanning and personnel location.This technology, combined with the working surface protection system of the centralized control system of the working face equipment, the precise control technology for the full process of intelligent mining of the rib spalling with large mining height was formed. The control technology was incorporated into the intelligent mining control system of the working face, which effectively solved the problem of intelligent mining coal rib control. The support worker was reduced from five operators to unmanned operation with one person as patrol. In Huangling No.2 Mine, the intelligent mining of large mining height was successfully implemented, and the annual output of the working face reached 6 million tons.
