炮孔填塞对爆破作用效果的研究
INFLUENCE OF BOREHOLE STEMMING ON BLASTING EFFECT
【摘要】 利用爆破理论和应力波理论,对炮孔填塞物的作用机理及其在炮孔中运动过程进行了分析,推导了炮孔填塞长度的计算公式,并对合理炮孔填塞长度的选取进行了现场试验。试验结果表明了理论分析的正确性,可为爆破实践提供理论依据。
【Abstract】 According to blasting theory and stress wave theory,stemming mechanism and movement of stemmed material in borehole were analyzed.The expression of length of stemmed material was deduced.The blasting experiment on the selection of reasonable stemming length was carried out.The experimental result showed that the theoretical analysis was correct,and could be used for theoretical basis of blasting practice.
