Planning of mining operations in the quality management mode based on geoinformation modeling

Deterioration of geological conditions of mineral mining and the tightened requirements imposed on the content of useful and harmful components and on the mineral product requires modern approaches to mining with the use of the latest methods of geoinformation modeling with minimal financial and time costs. The article presents a method of quality-based geometrization of titanomagnetite ore deposit using geoinformation support provided by mining and geological information systems (GGIS) to identify technological types of minerals in order to increase the efficiency of extraction of valuable components. It is proposed to appraise an ore body inside the closed boundaries of underground excavations and certified blocks. For this purpose, the frame models of ore bodies are constructed on the basis of digitized sections of horizon-oriented plans, longitudinal and transverse sections, as well as roof and floor plans. The algorithm of detecting promising areas for application of pretreatment quality control is presented as a case-study of variability of titanomagnetite ore quality. The proposed methodology is intended for automated planning of mining operations in the quality management mode with regard to statistical and economic criteria toward efficient subsoil use.
