| Abstract: | GPS RTK technology was introduced to solve some existing problems about holes arrangement in domestic open pit mine. Theories of accurate and precise measurements and holes arrangement were analyzed. Results show that the application of the RTK technology, compared to the previous ways used to holes arrangement, significantly facilitates in the position accuracy and efficiency. The error of holes arrangement has been decreased by about 20% as well as the efficiency increased by 1 times. Block rate has been effectively reduced from 5.0% to 2.6%. Improvement of blasting effect has been achieved, the secondary blasting and digging costs are saved, and accordingly good economic benefits are obtained. |
