露天药室大爆破。在矿山基建、采矿、铁路、水利等土方工程中有着广泛的应用。条件适宜时,采用大爆破进行土石方施工,可以收到缩短工期、节省大量设备费投资等一系列明显的技术经济效果。历来,大爆破设计都采用“手工”方式进行。设计中除需进行一些繁琐的数字计算外,耗时最多的是要处理一系列与地形有关的几何课题。例如,每定一个药室位置,除反复的数字计算外,都要在地形图上切出许多剖面、反复试凑。直到满足各方面的技术要求为止。这样,做一个规模不大的药室爆破设计,一般也要花费一月左右的时间。而要
Open-air large blasting. In the mining infrastructure, mining, railways, water conservancy and other earthworks has a wide range of applications. When the conditions are right, large-scale blasting for earthwork construction can receive a series of obvious technical and economic effects such as shortening the construction period, saving a large amount of investment in equipment costs, and the like. Historically, the design of big blasting has adopted “manual” approach. In addition to the design of some cumbersome numerical calculations, the most time-consuming is to deal with a series of topographical issues related to the geometry. For example, every time a pharmacy location, in addition to repeated numerical calculations, the cutout must be in the topographic map of many cross-sectional trial and error. Until meet all technical requirements so far. In this way, to do a small-scale pharmacy blasting design, generally spend about January or so. And want
