GPS Automatic Drill Hole Arrangement System for Open-pit Mines


System Introduction

Based on high precision and centimeter-level global positioning satellite technique, the GPS Automatic Drill Hole Arrangement System for Open-pit Mines can realize drill to be precisely positioned. The positioning technique is used in the process of hole arranged and punched, to advance the automatic level and precision of hole arranged and punched, and achieve fine management and digital control.

System Composition

Intelligent Terminal
The main task of the terminal is to collect positioning information, punched hole positioning, gather information of drilling machine’s condition, display drilling machine’s positioning information and communicate with ground control center.

Differential station in Ground Control Center
The reference station network can offer two types of service for sub-system of user system, and one is called non-real time and high precision positioning service, that is the reference original data is non-real time calculated by the sub-system to obtain the position data of centimeter-level, and the other is called real-time and high precision positioning service, it releases RTK differential data (1-5cm) used reference station MESH network. The reference station network also can offer other users to download relevant data from the central server, to enhance system availability.

The Ground Control Center
It used for analyzing the data of drilling machines and calculating mathematic model, interfacing with other systems, such as geology system, measuring system and mining system, exchanging hole site coordinates of drilling machines, converting coordinate system, and transmitting data to information-based system to statistical analysis.
