我们用药室爆破是自1957年起,通过学习先进单位,并经交通部科学研究院的协助指导下逐步发展起来的。但是由于我们水平低,自感很不完善,还恐存在错误,请同志们提出批评指导。一、关于药包定位 (一)药包的布置 1.步骤:布置药包时要: (1)核对测设图表,调查地形地质水文的情况和主要控制点(主要药包位置); (2)在平、纵、横断面图上综合考虑主药包以外的其它药包的总体布置。其它药包的布置,可先利用路线纵横断面图,绘出最小抵抗线折线草图来进行初步试定; (3)按布置图在实地初步放样定出桩志,组织领
Since 1957, our laboratory blasting has gradually developed through the study of advanced units and the assistance of the Ministry of Science and Technology. However, due to our low level of self-inductance is not perfect, there are still some errors, please comrades criticism and guidance. First, on the positioning of the kits (a) the layout of the kits 1 steps: when the kits are arranged: (1) check the mapping set to investigate the situation of terrain and hydrology and the main control point (the main package location); ) In the flat, vertical, cross-sectional view of the main packages in addition to consider the overall layout of other kits. The layout of other drug packs, the first use of vertical and horizontal cross-section of the route map, draw the line of minimal resistance line sketches to make a preliminary test; (3)
