| Abstract: |
| The traditional charging and blasting methods are backward in the domestic underground mines. Charging efficiency, charging quality and blasting safety are difficult to meet the needs of the high quality development of the mine. Combined on the practice of the application using the technology of site mixing and loading system for explosive which was used in the Xing-shan underground mines，this paper full introduced the mature technology which composed of charging truck of the type BCJ-4(I) and supporting ground station for the underground mines. The practices had been proved that the technology was safe, efficient, reliable and automatic, the new technology could be used for transporting the emulsion matrix for underground mining in long distance, and also could be met the requirements of automatic loading and coupling charging explosive in 40 m deep up-hole. Compared with the traditional charging methods of the underground mines, the new technology had the advantages of higher working efficiency, lower labor intensity and better blasting effect. It was believed that the new technology would be guarantee for deep and efficient mining of underground mines. |
