Determination of magnetic rock intrusion using lithology interpretation method
利用岩性解释方法圈定岩浆岩侵入煤层范围

The lithology seismic inversion technique utilizes logging data with high vertical resolution,and accomplishes the constrained inversion of seismic data nearby wells.The seismic data between the wells are inversed on the base,and deduce the lithology variation of coal-bearing stratum.Spectral decomposition technique utilizes the characters of lamella disperse frequency,analyzing the spectral changes of complex stratum and analyzing local phase instability to identify the landscape distributing characters of thin stratum.In this paper,real seismic data of the third excavating area of Cui Zhuang coalmine are dealt with lithology interpretation method such as seismic inversion technique and spectral decomposition technique to confirm the area of igneous rock.
