文章简要介绍了非炸药安全破碎器的构成、工作原理和操作步骤,归纳了非炸药安全破碎器处理大块岩石破碎效果的主要影响因素,钻孔位于岩块中心位置,孔深与岩块高度之比为2/3～3/4,岩块裂隙不发育,利于大块岩石破碎；分析了岩块体积大小与冲击波管使用数量、布置方式的匹配关系；证明了破碎器能够达到破碎大块岩石的目的,破碎过程几乎不产生飞石,最小安全距离为7m,安全性高,破碎大块岩石基本不受空间限制.%The article introduced the structure, principle of work, operating procedure of the boulder buster cartridge, and generalized the main factors to affect rock crushing effect by the boulder buster cartridge. When the hole laid in the rock center, the proportion of the hole depth and rock height was between 2/3 to 3/4, and the rock fracture was unobvi-ous, the crushing effect would be very well. The matching relationship of rock volume, number and layout of cartridges were also analyzed. Results showed that the crushing device was able to break rock commendably, with almost no splashing rocks during the breaking, and it showed good security as the safe distance was 7 m, with no space limitation during the large rock crushing.
