摘要
Based on the critical "size effect" analysis of single factor or multifactor coupling in large mining height working face, the definition and connotation of ultimate mining were put forward. The key issue that the large mining height working face could realize safe, efficient and good economic benefits was determined by scientific quantification of thick seam mining intensity. Then the mining intensity evaluation model based on entropy was set up and realized horizontal contrast among large mining height working face with different occurrence conditions. The attribute recognition method effectively solved the adjacent interval ordered partition problem of evaluation index about geological and mining condition. Because of the evaluation index easy to obtain, simple calculation process, and objective evaluation result, this model provided a more scientific approach to mining intensity classification evaluation of in large mining height working face. © 2018, Editorial Board of Journal of Mining & Safety Engineering.
