青阳白云石矿采场回采顺序优化

青阳白云石矿原设计为山坡露天开采,爆破警戒范围为200m,矿山生产已影响矿区南侧300m爆破警戒线范围内村庄安全生产、生活,同时也对东西横贯矿区的318国道产生直接影响。本文在原开采方案设计基础上,将采场回采顺序进行优化,分两期进行开采,以减少及消除对矿区南侧318国道和村庄的影响,从而达到更加充分、合理、安全利用采矿权范围内矿产资源之目的。

Optimization of stope mining sequence of Qingyang dolomite mine

Qingyang dolomite mine formerly was designed as open pit mining, and the blasting cordon range was 200m.However, the development of mine had affected the safety of production and livelihood within the south area 300m blasting cordon range, and the east-west state road 318.In this paper, based on the former mining plan, the stope mining sequence was optimized into two phases in order to reduce, and even eliminate the impact to the village and state road 318 on the south side, to achieve the more adequate, rational and safe use of mineral resources.
