块状岩体台阶爆破炮孔填塞作用的研究

本文利用电磁测量法及高速摄影法对块状模型中炮孔填塞物在孔内的运动规律和块体移动过程进行了研究。根据模拟试验及一些生产爆破的观测结果，对炮孔填塞机理提出了一些新的观点；同时就露天矿台阶爆破炮孔填塞长度及材料对爆破效果的影响作了简要分析。

Study about Blasthole Stemming Effected on Bench Blasting of Blocks Rock

In this Paper, a new electric-magnetic methed and high-speed Photography are used to study the stemming movement in the blasthole and block movement of the blocky medium model .Based on the results of the experiments in lab. and some Producing blasting,the Some new Viewpoits about stemming mechanism are gived, also. the stemming length and material influenced on the results of bench blasting in Open Pit are briefly analysed
