【摘要】 基于爆破理论和应力波理论,分析了炮孔堵塞物的作用机理及其在炮孔中运动过程,推导出了炮孔堵塞长度的计算公式,并对合理炮孔堵塞长度的选取进行了现场试验,试验结果说明了理论分析的正确性,可为爆破实践提供理论依据。更多还原

【Abstract】 According to blasting theory and stress theory,stemming mechanism and movement of stemmed material in blasting are analyzed and the expression of length of stemmed material is deduced.The blasting experiment with different stemming length is carried out and the experimental results show the theoretical derivation and analysis are correct.It will supply parameters design of blasting with the theoretical gist.更多还原
