岩石爆破孔壁动态初始压力测试系统研究

A Testing System of the Dynamic Primary Pressure on Hole Wall in Rock Blasting

本文根据锰铜压阻传感器耐高压、频响特性好和温度系数小等特点。

On the basis of the pressure resistant and frequency response properties of manganin pressure resistance sensor and the charactcristics of its low temperature coefficient, a testing system of the dynamic primary pressure on hole wall in rock blasting was extablished which is mainly composed of manganin pressure resistance sensor.
