摘　　要：河南省偃龙煤田位于基岩低山丘陵—黄土山坡向平原过渡地带,地形条件极为复杂,区内居民点、工业园区密集,公路较少,地震勘探施工难度大。此外,浅层地震地质条件差,地震数据采集难度大。偃龙煤田西村煤矿勘查经历了普查、普查续作和详查三阶段地震勘探工作,为了取得较好的地震勘探效果,各阶段地震勘探都经历了的数据采集反复试验,在此基础上才取得了勘探成果,因而也积累了该区地震勘探数据采集经验。重点总结介绍该区不同地貌地表条件下,二维地震勘探各种激发方式、采集参数和最终勘探成果,以供读者参考。Yanlong coalfield in Henan Province is located in the transition zone from low mountain and hill of bedrock to loess hillside to plain.The terrain conditions are extremely complex.There are dense residential areas and industrial parks in the area,and there are few roads.It is difficult to carry out seismic exploration.In addition,the shallow seismic geological conditions are poor,so it is difficult to collect seismic data.The exploration of Xicun Coal Mine in Yanlong coalfield has gone through three stages of seismic exploration:general survey,continuation of general survey and detailed survey.In order to achieve better seismic exploration results,the seismic exploration in each stage has gone through repeated tests of data acquisition.On this basis,the exploration results have been achieved,and the seismic exploration data acquisition experience in this area has also been accumulated.This paper mainly summarizes and introduces various excitation modes,acquisition parameters and final exploration results of 2D seismic exploration under different geomorphic surface conditions in this area for the reference of readers.
