随着煤炭资源整合和煤矿兼并重组的进行,机械化开采水平大幅度提高,综采工作面的布局、巷道布置与开拓对地质构造信息的要求也越来越高。综采工作面的生产能力和效益在很大程度上依赖于小构造的查明程度。这些小构造的存在可导致掘采比增大、矿井突水、顶板冒落,且断层附近煤质低劣,严重影响煤矿生产。为此,必须在采区进行高分辨率三维地震勘探。要想取得理想的三维地震资料,野外数据采集是关键,而适宜的激发层位的选取是取得良好的野外资料的前提,也是后期的资料处理、解释及提交报告的基础。
With the integration of coal resources and coal mine mergers and acquisitions, the level of mechanized mining greatly improved, the layout of fully mechanized mining face, roadway layout and development of the geological structure of the information requirements are also getting higher and higher. The production capacity and benefits of fully mechanized coal mining face to a large extent depend on the degree of identification of small structures. The existence of these small structures can lead to the increase of digging ratio, water inrush in coal mines, roof falling, and the coal quality near the fault is poor, which seriously affects coal production. For this reason, high-resolution 3D seismic exploration must be conducted in the mining area. In order to obtain the ideal 3D seismic data, the field data acquisition is the key, and the appropriate excitation horizon is the prerequisite for obtaining good field data and also the basis for later processing, interpretation and submission of the report.
