摘要:
利用导电性测试、显微照相、爆轰性能测试等手段，研究在不同岩石结构中、距爆炸源不同距离时受到爆炸应力波作用后的乳化炸药的微观结构的变化情况。试验结果表明： 在一定强度的爆炸应力波作用下，乳化炸药会产生析晶破乳现象，在结构致密的岩石介质中，应力波对乳化炸药的影响距离约为药包半径的16倍；在裂隙丰富的岩石介质中，应力波对乳化炸药的影响距离大于300 mm，且乳化炸药受破坏程度与影响距离无线性关系； 在砂地介质中，应力波对乳化炸药的影响距离为320 mm。
Abstract:
By means of electric conductivity testing, microphotography and detonation performance test, the microstructure changes of emulsion explosive under the action of detonation stress wave in different rock mass and with different distances from explosion source were investigated. Experimental results show that the crystallization and demulsification of emulsion explosives will occur under the impact of detonation stress waves of certain intensity. In dense rock media, the influence distance of stress waves on the emulsified explosives is about 16 times of the radius of explosive package. In the rock medium with abundant fissures, the influence distance of stress wave on emulsion explosive is more than 300 mm, and the degree of damage has no linear relationship with the distance. In the sand medium, the influence distance of stress wave on emulsion explosive is 320mm.
