摘　　要：鹤煤矿区地震地质条件复杂,常规地震勘探存在采集困难、信噪比低、精细地质体解释误差大等问题。基于以上,在鹤煤矿区开展了高精度三维地震勘探,结合地质资料取得主要认识和成果:①采用高密度观测系统及适宜参数可改善单炮记录数据质量,采用GM Seismic(GMseis)层析静校正、叠前多域多方法噪声压制等技术可提高分辨率及信噪比,采用全三维精细解释系统可提升断层等地质体成像精度;②于区内解释3条背斜、4条向斜,于区内外解释二_(1)煤底板断层64条、新生界底界断层23条;③查明了区内二1煤层赋存情况,预测了二1煤层中部厚、南北薄的厚度变化趋势。本文验证了高精度三维地震在鹤煤矿区勘探的有效性和先进性,为鹤煤矿区后续安全、科学的生产提供了重要的地质依据,揭示了该方法在相近复杂地区具有进一步推广的应用价值。The seismic geological conditions of He coal mine area are complicated,and conventional seismic exploration faces challenges such as difficult acquisition,low signal-to-noise ratio,and large interpretation error of fine geological bodies.Based on the above,conventional 3D seismic exploration was carried out in He coal mine area,and the main findings and insights were obtained by combining the geological data:①the quality of single shot record data can be improved by using high-density observation system and appropriate parameters,the resolution and signal-to-noise ratio can be improved by using GM seismic(GMseis)tomographic static correction and pre-stack multi-domain-method noise suppression and other techniques,the imaging accuracy of geological bodies such as faults can be improved by using full 3D fine interpretation system;②three anticlines and four synclines are interpreted in the area,and 64 faults of coal seam II_(1) floor and 23 faults of Cenozoic bottom boundary are interpreted inside and outside the area;③the occurrence of coal seam II_(1) in the area was identified,and the thickness variation trend of coal seam II_(1) was predicted,which was thick in the middle and thin in the north and south.This paper verifies the validity and advancement of high-precision 3D seismic exploration in the He coal mine area,providing an important geological basis for the subsequent safe and scientific production of Hei coal mine area,and revealing that high-precision 3D seismic exploration has the value of further popularization and application in similar complex areas.
