【摘要】 复杂的地质构造和生产环境使得中国的煤业生产时常蒙受巨大的经济损失和人员伤亡,而地震槽波井下探测技术做为当前可探明煤层中局部小构造和异常体的有效技术,具备分辨率高和预测性强等特点,是煤矿生产中井下探测的一种有效的地震勘探方法.本文回顾了地震槽波勘探研究的发展概况,并基于地震槽波在煤层中传播的物理特征和影响煤层中地震槽波传播等主要因素,对地震槽波动力学特征方面已经开展的物理模拟和数值模拟工作进行了综合阐述,进而指出了地震槽波勘探存在的理论问题、应用难题和可能的发展方向.更多还原

【Abstract】 Coal production always suffers huge financial losses and casualties because of the complicated tectonics and production environment.It is the key problems to detect the small structure,abnormal body and the coal thickness in the development of underground coal mining,and In-Seam Seismic(ISS) is a effective means to solve these problems with its high resolution and strong predictability.In this paper,the development of channel wave seismic exploration technology was reviewed systematically.Considering the physical characteristics as seismic wave propagation in the coal seam as well as the main factors which influence the propagation of the channel wave,We summarized and discussed the analogue-numerical simulation on the dynamic features of In-seam Seismic.Then we pointed out the theoretical problems and practical challenges of ISS.Finally,we prognosised the potential future directions.更多还原
