Study of Seismic Inversion Technology Forecasting Sandstone Waterborne of Coal Roof

摘要

Mechanism of water Inrush indicates that water resources is the essential factor for water inrush, roof and floor sandstone aquifer is the main source of water in the shallow seam mining process, take advantage of the physical property that sandstone is porous medium, using logging-seismic-geological comprehensive prediction method to determine the position of the sandstone porosity where is rich in water, the delineation of the rich water area, provide the evidence for the work of mine Water.
