在煤矿生产过程中地下必然会出现采空区,并且随着煤层被开采挖掘,采空区会形成越来越多,与此同时,采空区及其上部地层的地球物理性质也会发生一定的变化。地震勘探能有效地解决地下物性差异明显的构造,随着三维地震勘探技术在煤田上的蓬勃发展,使得采空区的探测成为可能。下面本文主要阐述了菏泽的地理环境以及地质层,并在此基础上探讨三维地震勘探技术在菏泽煤矿采空区中的应用。
In the process of coal mine production, mined-out areas will inevitably occur underground, and as the coal seam is mined and excavated, the mined-out area will be formed more and more. At the same time, the geophysical properties of the mined-out area and its upper strata will also occur The change. Seismic exploration can effectively solve the structure with obvious differences in underground physical properties. With the vigorous development of 3D seismic exploration technology in the coal field, it is possible to detect the goaf. The following article describes the Heze geographical environment and geological layer, and on this basis to explore the three-dimensional seismic exploration technology in Heze coal mined-out area.
