在复杂地区进行地震资料时,尤其是在表层复杂的区块,如煤矿、沼泽、山地、等复杂地表类型的勘探工区,对工区的浅层地震地质认识至关重要,无论是在对第四系地表沉积的认识还是后期人为改造上都需要进行深入了解和认知方能为地震波激发井深的选择提供最有利的依靠。本文主要以煤田开发,浅层地震地质条件破坏为起点,结合表层调查情况深入分析地表原生土质和地表水改变程度,就怎样选择不同的激发井深进行简单说明。
Seismic data in complex areas, especially in complex surface areas such as coal mines, marshes, mountains, and other complex surface types of exploration work area, the shallow seismic geological knowledge of the work area is crucial, whether in the fourth Whether the understanding of surface sediment or the man-made reconstruction in the later period needs further understanding and cognition can provide the most favorable reliance on the choice of seismic well excitation well depth. Based on the in-depth analysis of the change of surface soil and surface water with the surface survey, how to select different excitation wells for a simple explanation is mainly based on the development of coalfields and the destruction of shallow seismic geological conditions.
