Research on the application of Seismic exploration technology in the protection of shallow water resources in northwest China

摘要

In northwest China, the widespread Laterite of Neogene Pliocene series (N2) is the direct aquifuge above Jurassic coal seam, which plays a vital role in the protection of shallow water resources. With the rapid growth of coal production in this area, the N2 Laterite was severely damaged by the extensive and excessive modes of production, which caused a series of ecological and geological disasters of shallow strata. Identifying the spatial distribution of N2 Laterite and interpreting its lithology are the basic work for the prevention and control of the mining failure of it. Based on the practical data of Cuimu Mine 22 panel located in Baoji city of Shanxi Province, the technology of seismic numerical simulation, impedance inversion and probabilistic neural network were used comprehensively in this paper, in order to study the application of seismic exploration technology in the protection of shallow water resources. The spatial distribution of N2 Laterite in this area was identified and the lithology and water-resisting property of it were evaluated through this study.
