煤矿掘进巷道地震反射波超前探测技术及应用
|
摘要
矿井巷道掘进过程中遇到的断层、陷落柱、破碎带等地质异常体,会直接影响掘进施工效率,同时会给矿井的安全生产带来极大的威胁。采用地震反射波法进行井巷超前探测,能够对掘进坑道前方断层构造及其异常界面的位置进行较准确的预报。在分析反射波法超前探测数据采集及处理解释方法的基础上,结合井下掘进巷道探测实例,介绍了地震反射波法超前探测应用成果。
The geologic abnormal bodies such as faults,subsided columns and fractured zones which were encountered in the excavation process of roadways will directly affect its excavation efficiency,and will also threaten the safe production of the mine.The use of seismic waves for roadway advance detection can accurately predict the position of the fault structure and its abnormal interface in front of the heading face.This paper described the application results of advance detection with seismic reflection wave method based on the discussion of data acquisition,data processing and interpretation methods and according to the real detection examples of the mine roadway.
