【摘要】 利用地震波真反射层析成像技术对西石门铁矿深部开拓工程进行了超前预报,分析了各种不利因素引起的地震波振幅变化对井巷地质超前预报效果带来的影响。对TRT地质超前预报系统布置参数进行了改进与创新研究,得出了震源、最小偏移距和炮间距最优参数。防止了重大突水事故的发生,为西石门铁矿后期进行的开拓工程提供了可靠的依据。更多还原

【Abstract】 By real seismic tomography imaging technique,a prediction was made for the deep mine engineering of Xishimen Iron Mine.The influence of seismic wave amplitude variation on prediction accuracy of tunnel geology was investigated.An improvement and innovation research on the layout parameters of TRT system was performed.The optimal parameters of seismic focus,minimal row spacing and shot interval were obtained.The research provides reliable basis for prevention of major water inrush,and the mine development of the iron mine.更多还原
