TLDR: In this paper, a decision support system for a freezing method based shaft sinking project is presented, which comprises a source data layer mainly used for storing detected data before and during freezing construction, a data acquisition layer is responsible for extracting data from the source dataset, and a data management layer establishes a data mart to reduce data processing workload according to different themes.

Abstract: The invention discloses a freezing control decision support system for a freezing method based shaft sinking project. The system comprises a source data layer mainly used for storing detected data before and during freezing construction, a data acquisition layer is responsible for extracting data from the source data layer and then loading cleaned and converted data into a freezing project data warehouse, and a data management layer establishes a data mart to reduce data processing workload according to different themes. Multi-layered analyzing and digging of the data are realized through data digging and OLAP (on-line analytical processing) tools in a data analysis layer, acquired knowledge is put into a knowledge base, and auxiliary decisions for certain analysis are achieved through knowledge inference. Comprehensive decisions of multiple models are achieved by a model base. A data display layer provides analysis results for related decision-making personnel through a front-end display tool (graphic user interface). The system integrates various detection, analysis and control in the field of freezing control and provides powerful decision support for freezing construction personnel to control freezing.
