摘要
新疆戈壁滩地表一般为戈壁、丘陵地貌,地形差异大,砾石区速度、厚度变化大,使得施工难度增加,难以取得高信噪比的资料;并且地下构造复杂,地下资料成像困难,最终成果无法满足对煤矿的生产指导。为解决这些问题,针对新疆哈密某矿开展精细三维地震勘探,使用可控震源,坚持三高(高信噪比、高保真、高分辨率)原则,选取合理采集参数、处理流程以及精细解释方法,提高资料采集品质、处理成果,最终地震成果与采掘对比揭露准确率明显提高,为矿区后续工作面的合理布局以及安全开采提供可靠依据。
The surface of Gobi desert in Xinjiang is generally Gobi and hilly landform,with great terrain difference and great variation of speed and thickness in gravel area,which makes the construction more difficult and makes it difficult to obtain high signal-to-noise ratio data;and the underground structure is complex,underground data imaging is difficult,the final results can not meet the production guidance of coal mine.In order to solve these problems,a fine 3D seismic exploration was carried out in a mine in Hami,Xinjiang.Vibroseis was used,the principle of three high(high signal-to-noise ratio,high fidelity,high resolution)was adhered to,the reasonable acquisition parameters and processing flow were selected,the data acquisition quality and processing results were improved,and the accuracy of the final seismic results and mining comparison was significantly improved,it provides a reliable basis for the reasonable layout and safe mining of the follow-up working face in the mining area.
