淮南煤矿三维地震勘探技术应用与效果

RESEARCH AND ACHIEVEMENTS OF THREE DIMENSIONAL SEISMIC PROSPECTING TECHNOLOGIES IN HUAINAN COAL MINES

如何有效精细探明煤矿地质条件和准确预测地质灾害,为煤矿安全生产与发展提供了坚实的地质基础,近20年来,淮南矿业集团与有关单位合作,开展了三维地震勘探技术应用研究,在地震采集、处理和解释技术应用方面取得了丰富的研究成果。近年来利用三维地震勘探已发现较大特殊地质异常体,诸如陷落柱、新地层构造、旋转构造等;在地震地质条件较好的地区,能够基本查明主要煤层落差2m断层。实践表明,三维地震勘探技术不断发展,煤矿地质技术保障水平明显提高,企业综合效益明显增强。

In order to precisely detect the geological condition and abstractly forecast the geologic hazards,lately 20 years,Huainan coal mine（corporation） limited liability company in long-term cooperation with related Departments has carried out the research of application technology of three dimensional seismic prospecting and got enough positive result in seismic acquisition configuration,processing and structure elucidation.Recently,the three dimensional seismic prospecting technology has dug out lots of geologic anomalous body such as the collapse column,geotectonic and altun-fault etc.;The technology of precisely detecting can basically find out the faults with fault throw more than 2m on good geologic condition.The fact indicates the geologic security level in coal mines has been elevated significantly,also the performance of enterprises obviously has been improved,while the three dimensional seismic prospecting technology develops continuously.
