【摘要】 地面地震是一项成熟的技术手段,如何将地面地震技术成功地移植到煤矿井下,仍是世界各国一直探索和研究的问题。为此,回顾了国内外煤矿井下应用槽波探测工作面内部构造、利用瑞雷波进行独头巷道超前探测、利用声发射技术预报煤与瓦斯突出危险区和利用微震观测确定"三带"发育高度等技术的应用现状,指出了煤矿井下地震勘探技术存在的理论问题和工程应用难题,展望了煤矿井下地震勘探技术今后的发展前景。更多还原

【Abstract】 Surface seismic exploration is a proven technology.It poses great challenge when transplanting surface seismic technology to the underground in coal mine.This paper reviewed the advances in underground seismic exploration in coal mine.ISS(In-Seam Seismic) has been used to detect the structure in work face,Rayleigh waves to predict the variations in laneway ahead,acoustic emission(AE) to predict the dangerous areas of coal and gas overburst,and microseismic monitoring to determine the height of fracture.We summarized some theoretical and engineering problems existed for underground seismic exploration,and pointed out the development trend of this technology in the foreseeable future.更多还原
