摘要
赵庄煤矿小断层、陷落柱发育,给煤矿的安全生产带来较大威胁,查明小构造等地质异常是煤矿安全生产中的重中之重。在三维地震勘探解释过程中采用常规及方差体、谱分解、混沌地震属性相结合的方法对小构造进行控制。结果表明,该技术对小断层、较小陷落柱解释具有明显的优势,能解释出更小的地质构造,具有广阔的应用前景。地震勘探所获地质成果资料经矿方巷道验证,取得了较好的地质效果,为煤矿的安全生产提供了可靠的地质保障。
The development of small faults and collapse columns in Zhaozhuang Mine made a great threat to the safety of coal mine production. Identifying geological anomalies such as small structures would be the top priority in coal mine safety production. In the process of three-dimensional seismic exploration and interpretation, the small structures were controlled by the combination of conventional quadrat, spectral decomposition and chaotic seismic attributes. The results showed that this technology had obvious advantages in the interpretation of small faults and small collapse columns, which could explain smaller geological structures and had broad application prospects. The geological results obtained by seismic exploration had been verified by the mine roadway, and good geological results had been achieved, which provided a reliable geological guarantee for the safe production of coal mines.
