摘要
文中通过数值分析和计算,讨论了粘土爆炸压实效果与柱形装药之间的关系。炮孔堵塞是影响压实效果的重要因素。在炮孔堵塞长度较小时,炸药威力对爆炸空腔半径的影响不大。在无限粘土介质内,爆炸空腔半径达到最大值,对于2号岩石硝铵和泰安炸药,空腔半径分别是炮孔半径的15和26倍。
The relationship between the press effect of clay by explosion and cylinder charge is discussed by a numerical analysis and calculation in this paper. The blasthcle stemming is an important factor affecting the squeeze of the clay. The shorter the stemming length is, the less the effect of the explosive porvers on the explosion cavity radius is. In the infinite clay, the explosion cavity radii in infinite clay are as large as 15 times and 26 times of the blasthole radius for 2~ rock ammonium nitrate and PETN respectively.
