随着开采深度及开采范围的扩大,深层地质构造对煤矿安全的影响日趋加剧。高精度三维地震能判别地下层状介质的断层及陷落柱等地质构造。本文以山西左权某煤矿区为例,利用三维地震技术,分析了地下褶曲、陷落柱、断层等隐伏构造,为防范煤矿的地质灾害提供了依据。 With the mining depth and the expansion of the mining range, the impact of deep geological formations on coal mine safety is increasingly aggravated. High-precision 3D seismic can discriminate the geological structure of underground layered media such as faults and collapsing columns. Taking Zuoquan coal mine in Shanxi Province as an example, this paper analyzes the concealed structures such as underground fold, collapse column and fault using 3D seismic technology, which provides a basis for preventing geological disasters in coal mines.
