摘　　要：河南省巩义地区上庄煤矿位于华北板块南缘的嵩箕构造区西缘。区内地形较复杂,梯田冲沟多,人员活动频繁。在采用二维地震勘查技术时使用炸药震源审批难度大。鉴于井田内主煤层埋深不大,地表多致密黄土覆盖,激发地震条件较好,具备二维地震勘探中采取重锤方式激发震源的条件,与可控源地震剖面相辅相成,进行数据资料联合解释。查明区内煤层构造形态及其埋深变化、断层详细等参数。结果表明,该区基本由走向近南北的逆断层将煤层构造形态分成东西2部分,均为由东向西倾斜的单斜地层构成。研究区内开展落锤实验、可控源实验获取了有效参数表明,在工矿区经合理实验后采用机械震源亦能取得较好的勘探效果,具有一定的推广应用价值。Shangzhuang Coal Mine in Gongyi area,Henan Province,which is located in the western edge of Songji tectonic area on the southern edge of North China plate.The area is complex in shape,with many terraced fields and gullies and frequent personnel activities.It is difficult to approve the use of explosive source when using two-dimensional seismic exploration technology.In view of the small burial depth of the main coal seam in the well field,the surface is covered with dense loess,and the conditions for triggering earthquakes are good.It has the conditions for using a heavy hammer to trigger the source in two-dimensional seismic exploration,and it complements the controllable source seismic profile for joint interpretation of data and data.To find out the parameters such as the structural form of the coal seam and its buried depth change,fault details in the area.The results show that the coal seam structure in this area is basically divided into east and west two parts by the reverse fault with the strike of nearly north-south,which are both composed of monoclinal strata inclined from east to west.Effective test parameters are obtained through drop hammer experiment and controllable source experiment in the research area.It shows that in the industrial and mining areas,the use of mechanical seismic source can also achieve better exploration results after reasonable experiments,which has certain popularization and application value.
