| Abstract: |
| The research into explosion pressure on the wall of a borehole occupied a very important place in the study work about the mechanism of rock fragmentation by blasting.Experimental methods for directly measuring the hole-wall pressure by manganese-copper sensor were groped in this study.The pressures on the wall of boreholes in cement mortar or plexiglass and under coupling and decoupling charges were measured and studied.Experimental results indicated that direct measurement of explosion pressure on the wall of a borehole by manganese-copper sensor is feasible. |
