FIELD TEST OF DETONATION VELOCITY AND RELATIVE EXPLOSION PRESSURE OF AQUEOUS EXPLOSIVES IN DEEPHOLES |
| |
| Abstract: | The field test of detonation velocity and relative explosion pressure of aqueous explosives in deepholes was carried out jointly by Changsha Research Institute of Mining and Metallurgy, Daye Iron Mine of Wuhan Steel & Iron Company and Nanfen Open Pit Iron Mine of Benxi Steel & Iron Company. Test results indicated that two measuring methods with respectively a modified probe—detonation velocity digital meter and a tourmaline piezoelectric crystal sensor—transient waveform recorder can provide the reliable data for the improvement of fragmentation quality and large scale interference seismic reduction. |
