摘　　要：根据河南新郑某勘查区黄土较厚且无潜水位、煤层反射波较弱、滑动反射波能量更弱的特点,采用深井大药量高叠加次数激发,高分辨率数字地震仪(408UL)接收,保证了野外原始数据的采集质量。针对原始资料干扰波强及地形变化大的特点,资料处理采取以提高信噪比为主的措施,勘探取得了较好的效果。In one exploration area of Xinzheng city,there are the characteristics of thick loess,no underground water,weak seam reflected wave and weak slide reflected wave energy.By using superposition of large dose of high-frequency excitation,high-resolution digital seismograph receiver,the quality of the collection of raw data is ensured.Based on strong interference wave and large topographic variation,the measures of improving the signal to noise ratio are took in data processing.The exploration achieved good result.
