在新疆准东煤田预查中，采用二维地震勘探正演及波阻抗反演技术解释了复煤层宏观结构、预测煤层厚度，并综合采用钻探与地震资料估算煤炭资源量，其精度明显提高，与最终井田勘探所获得的煤炭储量累计值误差仅3％。该成果使得综合勘查技术得以在新疆煤炭资源勘查中推广应用。
在新疆準東煤田預查中，採用二維地震勘探正縯及波阻抗反縯技術解釋瞭複煤層宏觀結構、預測煤層厚度，併綜閤採用鑽探與地震資料估算煤炭資源量，其精度明顯提高，與最終井田勘探所穫得的煤炭儲量纍計值誤差僅3％。該成果使得綜閤勘查技術得以在新疆煤炭資源勘查中推廣應用。

In the pre-investigation in Xinjiang Zhundong coalfield, 2D seismic exploration technology, such as forward modeling and wave impedance inversion, was used to explain complex seam macro-structure and predict coal seam thickness. The accuracy of the estimation of coal resources has been significantly improved because of using combination of drilling and seismic data. The difference is only 3% between the estimation and the cumulative reserves of the final exploration. The prediction results have been fully affirmed by the Ministry of Land and Mineral Resources .The results have resulted in the application of the integrated exploration technology in the investigation of coal resources in Xinjiang.
