摘要
从山西晋城小窑采掘现状入手 ,结合钻探制作煤层全采、未采、半采三种模型的合成地震记录换层分析 ,分析其波形特征 ,标定了时间剖面上的采空区段与矿方实际采空区基本吻合。
Starting from the present situation of the excavation of small coat pits in Shanxi Province and connecting with the analysis of seismographic record produced by the integration of three modes of complete excavation,abundant excavation and half excavation, this paper analyses on the characteristics of its wave forms, and demarcates that the goaf on the time section basically tallies with the real goaf in the coal mine.
