摘　　要：开滦林南仓矿位于华北平原北部,地面建筑物密集、煤层倾角大、地质构造复杂。为取得较好的三维地震勘探效果,针对该区的施工难点,采用了特殊观测系统设计与施工方法,确保障碍物地段覆盖次数与全区保持一致;在资料处理时采用了叠前时间偏移处理技术和目标处理技术,有效解决了陡倾角复杂地质构造成像及多煤层识别等难题。The Linn ancang coalmine,Kailuan is situated in the northern North China Plain,with developed economy,dense population,closely spaced surface buildings,large coal seam dip angle and complex geological structures.For obtaining of better 3D seismic prospecting effects,in allusion to the operational nodi in the area,special observation system design and operation methods have adopted to keep folds in the obstacle sectors coincide with folds in the whole area.In data processing,prestack time migration and object processing technologies have adopted,thus nodi of steep dip angle complex geological structural imaging and multiple coal seams recognition solved effectively.
