【摘要】 在渔塘成片的湖区，常规二维地震勘探无法达到精查勘探程度，规则三维测网布设困难，针对此种条件，采用人机交互方式设计的三维特殊观测系统进行地震勘探（简称特观三维），经滕县煤田（北部）五号井田首采区试验，取得了明显的经济效益及较好的地质成果。更多还原

【Abstract】 In lake country densely covered with pounds,routine 2 D seismic exploration cannot reach upon elaborate perambulation degree,connot layout regular 3 D survey net too.In this paper,it primarily describes the method that rational economic and various flexible 3 D special observation systems are devised and carried through seismic exploration by using advanced equipment and adopting man machine interactive method on this condition (following for short special 3 D observation).In Number Five Field first mining area of Tengxian Coalfield,with the method of seismic exploration of special 3 D observation,it has brought obvious economic benefit and quit good geologic effect.更多还原
