通过二维、三维地震勘探结合地震正演数值模拟及波阻抗反演结果来预测新疆准东煤田大井矿区三井田B1煤层结构，定量解释了B1煤层一次分叉合并区范围，并准确预测了一次分叉合并区0．8～2 m厚的夹矸的范围。经过钻孔验证，该方法精度高，为矿井开采及巷道布设提供了准确的地震地质资料。
通過二維、三維地震勘探結閤地震正縯數值模擬及波阻抗反縯結果來預測新疆準東煤田大井礦區三井田B1煤層結構，定量解釋瞭B1煤層一次分扠閤併區範圍，併準確預測瞭一次分扠閤併區0．8～2 m厚的夾矸的範圍。經過鑽孔驗證，該方法精度高，為礦井開採及巷道佈設提供瞭準確的地震地質資料。

Through second and third seismic exploration method , combining with the forword numerical simulation and wave impedance inverson , structures of B 1 coal strata in No .3 coal well in Dajing coal mine of Zhundong coal field in Xinjiang have been predicated , bifurcation and combination scope of B 1 coal strata has been primarily ex-plained quantitatively , and the range of 0.8~2.0m thickness of gangue in B 1 coal strata has been accurately fore-casted .After drilling verification , it is regarded that this method is feasible with high precision .It will provide accu-rate seismical geologica data for coal mine .
