条形药包爆破块度模型初探
Based on the blasting softening technology for hard top coal in long-wall top coal caving, asimple fractal model of rock fracture is establishedto deal with dissipated energy of rock fracture andfractal dimension of rock fragmentation and to obtain the theoretical relation between the fractal dimension of rock fragmentation and explosive specific charge.
基于综放开采预爆破弱化坚硬顶煤工艺，利用分形理论建立岩石断裂耗散能量与块度分维值之间的理论关系，推导出岩石爆破块度分数维与炸药单耗之间关系，进行了室内相似材料模型爆破实验，验证了上述理论关系，利用爆破岩石表面裂隙分布的分形维数值作为衡量指标，优化爆破孔网参数。
