Annotation: This article proposed one of the solutions to the important today problem of optimal organization of man-made deposits consisting of mining waste for their further processing. A project is presented to abandon the waste dump facility as the final technological stage of mining operations in favor of storage. The purpose of the project to replace the waste dump facility with storage is to attract additional funds received from the sale of mineral raw materials of man-made mineral deposits. As evidence of the profitability of the considered project of transition from waste dumping to storage of mining waste, a schedule of changes in the cost of overburden and stored rocks over several years was compiled. To conduct a more advanced objective assessment of the effectiveness of the proposed project, possible designs of quarry waste warehouses, their positive and negative aspects in formation and development were considered. The considered warehouse designs and their parameters are theoretically presented in the conditions of the JSC "Kachary ruda" and subjected to an economic assessment. In the process of this assessment, it was necessary and sufficient to take into account only the costs of the transition to the storage of mining waste.

Annotation: Modern distance education requires rapid development of unique educational materials that are of high quality from a methodological perspective. This task creates a significant workload for teachers and methodologists. The aim of the article is to evaluate the effectiveness and practical applicability of various artificial intelligence language models (GPT-4, Claude 3.5 Sonnet and Gemini) for creating educational content using B2 level English language materials as an example. Research methods include comparative analysis of the effectiveness of language models, development of a structured methodology for creating educational materials, and evaluation of generated content according to four key criteria: compliance with B2 level, methodological value, uniqueness of material, and educational potential. Within the framework of the research, a detailed course structure was developed covering all aspects of language learning: grammar, vocabulary, speaking, and speech perception. The research confirms the high efficiency of using artificial intelligence in creating educational materials. Key advantages include significant reduction in content development time, the ability to quickly generate unique materials, and flexibility in adapting to individual student needs. Of particular importance is the methodological variability of generated materials, allowing for the creation of various task formats for developing different language competencies. At the same time, the necessity of professional moderation and refinement of automatically generated materials is emphasized to ensure their maximum educational effectiveness.
