摘要

Tremendous amounts of chemical and physical data are collected during pre-mine studies of overburden and native soils. Without computer enhancement, sorting, analyzing, and reporting of the data to meet regulatory requirements for surface mine permitting can be extremely time consuming. Studies to determine if topsoil substitution is a valid option at the Oxbow Mine in Northwest Louisiana are cited to demonstrate how such data management can be accomplished quickly and more effectively. Native soils at the mine are developing in very clayey Holocene alluvium that has severe limitations for crop production. Computerized correlation of the data into lithologic units was completed to show which overburden intervals were more desirable for use as topsoil substitute. Evaluations of the strata showed that material at lower depths is better suited for postmine topsoil. With proper mining procedures, postmine soils will have significantly better chemical and physical characteristics than the native soils at the Oxbow Mine.
