利用地震属性探测陷落柱的技术与应用
|
摘要
煤矿开采过程中经常遇见陷落柱,它是奥灰岩溶发育矿区的一种特殊地质现象。陷落柱有着孤立出现、大小不等、规律性差等特点,同时作为奥灰岩溶水的导水通道,极易引发矿井生产安全事故,影响开采进度,因此陷落柱的准确探测对于煤矿的安全生产和开采效率意义重大。煤矿陷落柱极易引发矿井生产安全事故。结合山西晋城某工区实例,利用三维地震勘探资料、陷落柱地球物理特征与属性特征进行瞬时相位、方差体、最大反射强度、瞬时频率等4种地震属性综合分析解释,陷落柱在该4种属性中异常特征明显,并在实例工区中验证情况良好,取得了较好的勘探效果。
In the process of mining often met collapse column,it is a special geological phenomenon of Ordovician limestone karst area.The collapse column with isolated occurrences,unequal in size,bad regularity characteristics,at the same time as the water guide channelof Ordovician limestone karstic water,extremely easy to cause safety accidents in mine production,affect the progress of mining.Therefore,the accurate detection of collapse column in coal mine safety in production and the production efficiency is of great significance.Coal mine collapse column is extremely easy to cause safety accidents in mine production.According to Shanxi some area in Jincheng as an example,using 3D seismic exploration data,subsided column geophysical characteristics and characteristics of the instantaneous phase,variance,maximum intensity,instantaneous frequency 4 seismic attribute analysis explain,column in the 4 attributes of abnormal features obvious collapse,and in the actual work of verification in good condition,good exploration result.
