前言露天药室爆破设计中最费工费时的工作是确定药室位置。它实质上是一个采用作图方法不断试凑的过程,即不断调整药室中心,直至各向抵抗线、药室间距等符合要求,而每调整一次药室位置,都要重新在地形图上选取最小抵抗线所在的方位(剖面线位置),切剖面,求最小抵抗线。可见,无论采用手工设计或是电算设计,最小抵抗线位置的确定都是首先要遇到并需要反复进行的一
Preface Open-air pharmacy blasting design of the most costly and time-consuming work is to determine the location of the drugstore. It is essentially a trial and error process using the mapping method, that is, continuously adjust the center of the pharmacy, until the resistance line, the pharmacy spacing to meet the requirements, and every adjustment of the location of the pharmacy, to be re-on the map Select the location where the line of least resistance (section line position), cut the section, find the line of least resistance. Can be seen, either by hand or computer design, the minimum line of resistance to determine the location of the first encounter and need to be repeated
