摘　　要：本研究旨在对广西靖西县新圩-三合矿区的堆积铝土矿体,通过矿区勘探阶段和生产勘探阶段数据,从面积重合率、形态歪曲误差、矿石资源量误差、矿厚误差、含矿率误差、品位误差等主要参数进行对比,探讨勘查网度的合理性并对同类矿床后续勘查网度提出合理的建议。通过对6个矿体的勘探与生产勘探主要参数对比,发现勘探阶段详细查明了主要矿体的矿体参数,但因勘探阶段对各矿体的工程控制程度不同,建议在生产阶段进行生产勘探。对于资源量的可靠程度对比表明,矿区总体矿石量相对误差在合理范围内,证明了勘查类型及勘查网度基本是合理的,研究结果为本矿区后续生存勘探提出了合理建议,为同类矿床的勘查和生产勘探勘查网度提供参考对比依据。This study aims to explore the rationality of the exploration network and provide reasonable suggestions for the subsequent exploration network of similar deposits in the Xinwei Sanhe mining area of Jingxi County,Guangxi.Based on data from the exploration and production stages of the mining area,the study compares the main parameters such as area overlap rate,shape distortion error,ore resource quantity error,ore thickness error,ore content error,and grade error.By comparing the main parameters of exploration and production exploration for six ore bodies,it was found that the ore body parameters of the main ore bodies were identified in detail during the exploration phase.However,due to the varying degrees of engineering control over each ore body during the exploration phase,it is recommended to conduct production exploration during the production phase.The comparison of the reliability of resource quantity shows that the relative error of the overall ore quantity in the mining area is within a reasonable range,which proves that the exploration type and exploration network are basically reasonable.The research results provide reasonable suggestions for the subsequent survival exploration of the mining area,and provide reference and comparison basis for the exploration and production exploration network of similar deposits.
