随着我国经济的迅猛发展,支撑经济的能源和矿产资源的开采技术遇到了新的挑战,特别是深凹露天矿的高边坡安全问题随着采矿的深入越来越突出。目前保护边坡的爆破开采技术主要是从降低爆破震动来减弱对保护边坡的损伤,预裂爆破作为边坡保护性开采技术的一种,其技术已较成熟,但在我国其操作过程很费时,为了寻找一种新的边坡预裂爆破装药方式,本文通过不同装药结构的预裂爆破对边坡损伤的检测,提出了空气间隔装药的边坡预裂爆破技术,并在工程中得到了很好的应用。
With the rapid economic development in our country, mining technologies that support the economy in energy and mineral resources have encountered new challenges. In particular, the issue of high slope safety in deep open-pit mines has become increasingly prominent with the deepening of mining. At present, the blasting mining technology for protecting the slope is mainly to reduce the damage to the protection slope by reducing the blasting vibration. As a kind of protective mining technology, the technology of the pre-cracking blasting is more mature, but in our country, the operation process is very Time-consuming, in order to find a new way of presplitting blasting on the slope, this paper proposes a pre-splitting blasting technology for slope preloading by means of presplitting blasting of different charge structures, The project has been very good application.
