摘要
为探明陷落柱发育边界、柱体胶结程度及富水性等情况,采用随钻地震探测技术对巷道掘进前方发育的陷落柱进行钻探分析。通过不同钻进深度下的能量异常及频谱差异等特征,精确得出随钻岩性变化情况,同时辅以综合物探方法相互验证,查明了陷落柱基本性质,消除了采掘活动的安全隐患。
In order to find out the development boundary of the collapse column,the cementation degree of the column and the water abundance,the seismic exploration while drilling technology is used to drill and analyze the collapse column developed in front of the roadway excavation.Through the characteristics of energy anomaly and frequency spectrum difference under different drilling depths,the lithological changes while drilling can be accurately obtained.At the same time,combined with the mutual verification of comprehensive geophysical exploration methods,the basic properties of collapse columns are found out,and the potential safety hazards of mining activities are eliminated.
