摘　　要：长期以来,受地震勘探技术应用成本高的制约,该技术在地浸砂岩型铀矿勘探工作中一直未能得到大范围的推广应用。通过借鉴石油和煤炭勘探开发过程中地震勘探技术的应用经验,结合地浸砂岩型铀矿勘探开发特点,分析了地震勘探技术在地浸砂岩型铀矿勘探开发中的应用前景,并对其工作部署提出了建议。认为地震勘探技术不仅可以查明地层、岩性、构造、沉积相、泥-砂-泥结构、砂体厚度变化等与铀成矿相关的环境条件,而且可以实现对地浸砂岩型铀矿的直接预测,并为资源储量的估算提供依据。此外,在地浸矿山开发的设计和开采过程中地震勘探技术可以解决局部小构造的发育、地层的起伏变化、矿体的连续性以及地浸液的分布范围等问题,从而为砂岩型铀矿地浸开采中抽注钻孔的设计提供依据,为实现矿山的精准开发提供技术支撑,同时还可以为后续地浸矿山的退役治理提供必要依据。For a long time,restricted by the high application cost,the seismic exploration technology has not been widely promoted and applied in the exploration of in-situ leachable sandstone uranium deposits.This paper summarized the application experience of seismic exploration technology in the exploration and development of petroleum and coal,combined with the characteristics of the exploration and development of in-situ leachable sandstone uranium deposits,analyzed the application prospects of seismic exploration technology in the exploration and development of in-situ leachable sandstone uranium deposit,and proposed work deployment recommendations.It is believed that seismic exploration technology can not only identify the environmental conditions related to uranium mineralization,such as strata,lithology,structure,sedimentary facies,mud-sand-mud structure,and sand body thickness changes,but also can realize direct prediction of in-situ leachable sandstone uranium deposits,and provide a basis for resource estimation.In addition,in the design and mining process of in-situ leaching mine development,seismic exploration technology can solve the development of local small structures,stratum fluctuations,continuity of ore bodies,and the distribution range of in-situ leaching liquid,which provide a basis for the design of pumping and injection drilling in in-situ leaching of sandstone uranium mines,and technical support for the realization of the precise development of the mine,and also the necessary basis for the subsequent decommissioning management of in-situ leaching mines.
