摘　　要：为了优化并合理利用砀山县矿产资源,促进砀山县国民经济快速发展,朱楼井田的开发建设是十分有必要的。此次勘探需详细查明勘查区内新生界厚度及底界面起伏形态,查明7、10煤层中落差大于50 m的断层的性质及延伸情况,查明7、10煤层起伏形态并初步了解7、10煤层厚度变化趋势。通过认真分析研究区地质资料并结合以往物探资料,认为二维地震勘查可满足此次勘探任务并部署14条测线总长100.84 km的地震测线。结果表明,二维地震勘探是查明构造情况、控制煤层赋存形态、以及断裂构造状况的借鉴手段之一,本文即阐述二维地震方法在井田勘探起到的作用并对此进行分析研究。In order to strengthen the development and utilization of mineral resources in Dangshan County,optimize and use mineral resources rationally,and promote the rapid development of national economy in Dangshan County,the development and construction of Zhulou mine field is very necessary.In this exploration,it is necessary to find out the Cenozoic sedimentary thickness and bottom interface fluctuation pattern in the exploration area in detail,to find out the nature and extension of faults with a drop greater than 50 m in No.7 and No.10 coal seams,to find out the fluctuation pattern of No.7 and No.10 coal seams and to preliminarily understand the thickness change trend of No.7 and No.10 coal seams.By carefully analyzing the geological data of the study area and combining with the previous geophysical data,it was considered that the two-dimensional seismic exploration could meet the exploration task and deployed 14 seismic lines with a total length of 100.84 km.The results showed that two-dimensional seismic exploration was one of the reference means to find out the structure,control the occurrence form of coal seam and the condition of fracture structure.In this paper,the role of two-dimensional seismic method in mine field exploration was expounded,analyzed and researched.
