为准确掌握煤矿工作面内隐伏的中小型断层发育等地质情况,将槽波地震透射技术和槽波地震反射技术综合应用于文家坡煤矿4106工作面进行地质条件探测。通过波场和速度分析、频谱分析、频散分析,确定文家坡煤矿4106工作面内槽波的有效频段以及噪声频段;为宽频带通滤波提供可靠依据,进行宽频带通滤波后,分别进行透射能量CT成像和反射叠加成像;根据成像结果综合解释,将透射能量CT成像解释结果和反射叠加成像结果相互印证,确定文家坡煤矿4106工作面存在2个异常区、2条断层,为该工作面的安全生产作业提供了地质依据。

In order to accurately grasp the geological conditions such as the development of hidden medium and small type faults within the coal mine working face and others, the slot wave seismic transmission technology and slot wave seismic reflection technology are comprehensively applied to the geological condition detection of the 4106 working face of Wenjiapo Coal Mine. Determine the effective frequency band and noise frequency band of the slot wave within the 4106 working face of Wenjiapo Coal Mine through wave field and velocity analysis, spectrum analysis, and dispersion analysis; to provide reliable basis for wide frequency band pass filtering, after conducting wide frequency band pass filtering, transmission energy CT imaging and reflection superposition imaging are performed separately; according to the comprehensive interpretation of the imaging results, the transmission energy CT imaging interpretation result and the reflection superposition imaging result are mutually confirmed, and it is determined that there are two abnormal areas and two faults in the 4106 working face of Wenjiapo Coal Mine, providing geological basis for the safe production operation of this working face.
