摘要
恒源煤矿深部采区进行三维地震勘探的主要难点为地表及地质构造复杂、煤层埋藏深且较薄、信噪比和分辨率低。针对以上难点,采取了优化观测系统、Klseis软件实时监测的设计措施,深井、小药量激发,村庄内检波点实测铺设的采集措施保证了覆盖次数的均匀合理。经精细处理及综合动态解释,取得了较显著的地质成果。
The complicated ground surface and geologic structure,deep and thin coal seam,low signal to noise ratio and resolution ratio were the main difficulties of 3D seismic exploration in deep mining area of Hengyuan Coal Mine.Aiming at above difficulties,observing system optimization and real-time monitoring by Klseis software were adopted as designing measures,drilling and small dosage stimulating and actual measurement of detection points in the villages were adopted as data collection methods to ensure the uniform and reasonable of coverage times.By precise processing and comprehensive dynamic interpretation,remarkable geology results were achieved.
