常规煤田三维地震勘探技术广泛用于煤矿采区的合理布置、主巷道的开拓、综采工作面地质条件的评价.但受自身方法和能力的限制,在不少矿区地震成果的井巷验证符合率低,精度不能完全满足煤矿开采的要求,严重影响到煤矿的安全生产.刘店煤矿106采区地质构造极为复杂,小断层极发育,煤层受岩浆岩侵蚀,地震数据的信噪比极低,利用常规三维地震勘探方法无法查明复杂的地质构造.通过在该区进行全数字高密度三维地震勘探试验,结果表明:全数字高密度三维地震勘探能够提高地震数据的信噪比和分辨率,有利于小断层等小地质目标体的成像,能够减少构造假象,反映煤层的真实构造形态,对指导煤矿高效安全生产意义重大.
Conventional coalfield 3D seismic exploration technology is widely used in the reasonable layout of the coal mining area, the development of the main roadway and the evaluation of the geological conditions of the fully mechanized mining face, but is limited by its own methods and capabilities. Low accuracy and precision can not fully meet the requirements of coal mining, seriously affecting the safety of coal mines. Liudian coal mine 106 mining area is extremely complex geological structure, a small fault pole development, coal seam by the magmatic rock erosion, seismic data very low signal to noise ratio , The complicated geological structure can not be identified by the conventional 3D seismic exploration method.The results of digital 3D high-density seismic exploration in this area show that digital high-density 3D seismic exploration can improve the signal-to-noise ratio and resolution of seismic data , Is conducive to the imaging of small faults such as small geological target body, can reduce the structural illusion, reflect the real structure of the coal seam, and guide the efficient and safe production of coal is of great significance.
