【摘要】 文章设计和介绍了低爆速细长震源药柱的结构和性能特征,并分析了该细长药柱的爆炸激发机制。试验表明,在低速激发介质的煤田地震勘探中,该细长药柱比高爆速TNT震源药柱激发的地震波能量强,频带宽,信噪比高,为煤田高分辨率地震勘探提供了一种新型震源。更多还原

【Abstract】 The structure and performance of the low detonation velocity and elongated source charge are designed and introduced, and explosive mechanism for the charge is also analyzed in this paper.The test results show that: the charge is stimulated to generate high energy and frequency and signal-to-noise ratio in the substrate of low speed of the longitudinal wave for coal seismic exploration, compared with TNT source charge of high detonation velocity.A new type of source charge is provided for coal seismic exploration of high resolution.It is worth to spread application.更多还原
