Current Challenges

Customers across the mining industry experience common problems when tagging/logging detonators:

Incorrect delay assignment due to
▪ Incorrectly marked blast holes
▪ Incorrect tagging of a hole or delay
▪ The lack of a blast plan

爆炸延迟
▪ Difficulty locating the correct blast hole
▪ Delays due to time taken to find a problematic hole when fault finding and troubleshooting on the bench

Blast outcomes
▪ Incorrect timing will impact blast results in fragmentation, loading efficiency, and overall productivity

Difference between 全球定位系统(GPS) and D全球定位系统(GPS)

正常的全球定位系统(全球定位系统(GPS)):
Provides a position of an object on earth using signals generated by satellites revolving around the earth.
全球定位系统(GPS) uses standalone receivers where the location is directly calculated but is also prone to errors such as orbit errors, multi-path errors and clock errors.
Provides a position of an object on earth using signals generated by satellites revolving around the earth.
全球定位系统(GPS) uses standalone receivers where the location is directly calculated but is also prone to errors such as orbit errors, multi-path errors and clock errors.
As a result 全球定位系统(GPS) can gain a nominal accuracy of 10 – 15 meters.

因此...
全球定位系统(GPS) is NOT suitable for accurate blast hole position

Differential 全球定位系统(GPS):
Accuracy of D全球定位系统(GPS) is achieved by using a reference receiver (CE4 Commander) at a known surveyed location that broadcast correction data to the Tagger.
Accuracy of D全球定位系统(GPS) is achieved by using a reference receiver (CE4 Commander) at a known surveyed location that broadcast correction data to the Tagger.
D全球定位系统(GPS) is a vast improvement from 全球定位系统(GPS). It reduces or eliminates signal degradation, resulting in improved accuracy.
The system provides sub one-meter accuracy for accurate blast hole tagging and logging. 

 

ViewShot 3 d Blast Design Software

ViewShot 3 d is a blast software that facilitates the planning, design  and simulation of the blast outcome.
Using D全球定位系统(GPS) in “plan mode”, the 全球定位系统(GPS) coordinates from the drill rigs are imported into ViewShot 3 d.

The blast design timing sequence is simulated and optimized using the timing design tools to achieve the desired outcomes.

The blast plan and timing sequence is then downloaded onto the D全球定位系统(GPS) Tagger, ready for Tagging.

D全球定位系统(GPS) Development Future Applications

Future applications using D全球定位系统(GPS) include, a standalone module enabling D全球定位系统(GPS) capability on other equipment, 微控制器的, drill rigs etc.; a common detonator list updated in real-time as multiple users or machines tag detonators; and centralized user interface – real time graphical update on deployment process.
