  • 摘要: 为解决我国煤矿采掘失衡、采掘接续矛盾的问题,通过分析国内外掘进技术装备的现状,探讨了掘锚平行作业和硬岩截割2个制约快速掘进的主要问题,介绍了掘锚一体化联合作业和硬岩截割新技术发展,如悬臂式掘进机机载液压锚杆钻机系统、单巷连续快速掘进成套设备、快速掘进系统等的设计,最后对掘进技术与装备的发展方向提出了展望和建议。

     

    Abstract: In order to solve the problems of a mining and excavation unbalancing and the mining and excavation connection contradiction in China coal mine, with an analysis on the present status of the mine heading technology and equipment at home and abroad, the paper discussed the main problems of the heading and boltin g parallel operation and the hard rock cutting, which could restrict a mine roadway rapid heading and introduced a heading and bolting integrated combined operation a nd a new technical development of the hard rock cutting, including the hydraulic bolt drilling system on a boom type roadheader, a complete equipment for a continued「 apid heading in a single mine roadway, a rapid heading system and others. Finally, the paper had a prospect and proposals on the development orientation of the mine「 oad heading technology and equipment.
