三维地质模型驱动的露天煤矿岩体爆破优化设计OA
Optimization design of rock mass blasting in open-pit coal mines driven by 3D geological modeling
针对露天煤矿软硬互层岩体爆破效率低、安全性不足的问题,提出基于三维地质模型的爆破设计优化方法.通过岩性地质编录与空间插值技术,构建高精度三维岩性模型,实现岩体结构的精准刻画.在此基础上,针对砂岩、泥岩、胶结岩的力学特性差异,设计了差异化孔网参数与层状装药方案.现场应用表明,该方法有效提升了爆破能量分布的均匀性,降低了爆破振动与岩体扰动,为复杂岩性地质条件下的爆破设计提供了新思路.
This article proposes a 3D geological model-based blasting design optimization method to improve the efficiency and safety in open-pit coal mining of soft-hard interlayer rock masses.By lithological geological logging and spatial interpolation technology,the article creates a precise 3D lithological mode,and realizes accurate characterization of rock mass structure.On the basis of it,aiming at differences in mechanical properties of sandstone,mudstone,and cemented rock,the article designs differentiated hole network parameters and layered charging schemes.Field results show that the method effectively improves homogeneity of blasting energy distribution,reduces blasting vibrations and rock mass disturbances,offering a new approach to blasting design in complex geological conditions.
