目前,随着煤矿综采机械化程度的不断提高,原地质精查时,由于技术装备和方法的限制,落差10～30m的断层未能完全查清,远远满足不了采区设计的需要,故对探明小断层的要求亦日益迫切。根据这些年的地震勘探工作实践,谈谈用地震反射波法勘探落差大于5m以上小断层的点滴经验。论述了用地震反射波法探测煤矿采区小断层,必须从野外工作方法做起,同时叙述了在资料解释对比时,断层在时间剖面上表现的各种特征。
At present, with the continuous improvement of the mechanical mechanization of mechanized coal mining, when the original geologic survey was conducted, due to the limitations of technical equipment and methods, the fault with 10-30 m drop failed to be completely identified and could not satisfy the design requirements of the mining area. The requirements for identifying small faults are also increasingly urgent. According to the practice of seismological exploration in these years, we talk about the drip experience of using seismic reflection wave method to survey the small faults whose drop height is more than 5m. Discussed the use of seismic reflection wave method to detect small faults in coal mining area, we must start from the field work method, at the same time describes the interpretation of the data in the contrast, the fault in the time profile of the various characteristics.
