槽波地震透射法在陷落柱探测中的应用研究

Application of Channel Wave Seismic Transmission Method in Detection of Collapse Columns

陷落柱是我国华北型矿井的主要地质构造之一,对煤矿的安全生产构成严重威胁。为了准确探明陷落柱的发育形态和影响范围,选择合理的试验现场,展开槽波透射法探测,综合研究陷落柱的地震波场响应特征。结果表明:当槽波射线穿越陷落柱时,其能量衰减严重,艾里相位清晰程度下降,且不连续,最终结合相应的计算方法,能够准确圈定陷落柱的赋存位置,对矿井的安全高产高效意义重大。

As one of the major geological structures of mines in North China,collapse column poses a serious threat to the safe production in coal mines.In order to accurately determine the development and range of the collapsed columns,channel wave transmission detection method was used to study the seismic wave field response of the collapse columns by selecting reasonable test sites.The results show that when the channel wave traverses the collapse columns,there were severe energy attenuation and decreased and discontinuous clarity of the Airy phase.the corresponding calculation was used to accurately delineate the location of the collapse columns,which was of importance to the safe and efficient production in the mine.
