基于GNSS的露天矿牙轮钻机钻孔导航定位模型与系统研究

摘要

In order to improve the drilling accuracy and simplify the construction process,a rotary drill navigation system based on GNSS technology was proposed which closely related to the efficient production in open-pit mine. On the basis of establishing the architecture of system,a location model contains planar positioning and depth positioning was put forward. In addition,the function of system was detailed discussed which included graphical display,informa-tion management,navigation and quality evaluation. Development of such a system had a significant impact on drilling process by assisting driver navigation in real-time,which has helped in productivity improvement and decreased extra work. Besides,it has provided a construction management for blasting designer which was meaningful to the digitali-zation monitoring in open-pit mine.%从提高露天矿穿孔工艺质量角度出发，采用GNSS卫星导航定位方法，设计并开发出用于支持牙轮钻机钻孔作业的导航定位系统。介绍了系统的组成结构，重点阐述了支持钻头实时导航的平面定位模型和孔深定位模型，并讨论其具备的图形显示、信息管理、导航定位和质量评估四个核心功能。该系统可以为司机实时提供牙轮机钻头的三维空间位置，指导其钻孔作业全过程，不仅保证了爆破孔网参数的准确性和爆破效果，而且减轻人员工作强度，提高露天矿穿孔工作效率，提升数字矿山的信息化建设水平。
