【摘要】 研究目的:复杂地形地质条件下煤矿采空区的勘察,依据地震反射是主要的技术手段,技术难点是如何合理的布线,采用保真数据处理技术,准确获取高信噪比、高精度数据,本文对此进行研究,提出相应的技术措施。研究结论:通过对太中线临县地形复杂地区和黄土塬地区的煤矿采空区的勘探,采用地震反射进行了一次成功实践;勘察中沿自然沟谷弯线施工,利用自然出露的基岩可"避虚就实",个别地段采用加密炮和调头炮来提高叠加次数;并在地震反射弯线处理上,合理选取CDP共反射面元范围,处理精度显著提高,可以准确确定煤矿采空区边界,为铁路选线提供了有利的地质依据。更多还原

【Abstract】 Research purposes: Seismic reflection is the main technical method for the gob exploration under complicated terrain and geological conditions,and the difficult points in technology are how to arrange lines reasonably and how to gain the high signal-to-noise ratio and high precise data with high-resolution data processing technology.This paper researches it and offers the relevant technical measures.Research conclusions:The seismic reflection was successfully used for the exploration of coalmine gob in the area with complicated geological terrain condition and in loess area in Linxian along Taiyuan-Zhongwei-Yinchuan Railway Line.During the investigation along the natural ditch,the natural superficial bedrock was used to reach the goal of"dwelling on the solid body and avoiding empty body",and in a specific area,the congested cannon and turnaround cannon were used for increasing the superposed times.For treatment of bend line of seismic reflection,the reasonable selection of CDP range of the plane of common reflection could improve the treatment accuracy remarkably and determine the boundary of coal gob accurately,which could provide the powerful basis for the railway route selection.更多还原
