Influence of Interval Charge on Broken Effect of Blasting
-
摘要: 用空氣、水和巖粉3種間隔材料進行了間隔裝藥爆破試驗,研究了間隔對破碎塊度的影響,得出3種材料的臨界間隔比例值,對比了該3種材料間隔與全長偶合裝藥的異同,討論了間隔的位置、長度及間隔材料對爆破破碎效果的影響。Abstract: Using water, air and rock powder as interval materval materials, the explosive experiment of interval charge is made. Interval effect on broken block degree is researched. The difference of interval charge of three materials and coincidental charge is discussed. Influence of position, length and materials on rock broken effect are analysed.
