Assessment of the effectiveness of lightweight mechanized complex with roof coal recovery at Mong Duong coal joint stock company - Vinacomin

Abstract

To establish a foundation for implementing lightweight mechanized mining technology in thick, gently inclined coal seam areas at underground coal mines in the Quang Ninh region, the author utilized expert methodologies combined with analysis and synthesis of specialized literature, scientific research projects, online resources, and AI technology to complete the study. The analysis and evaluation of the advantages, disadvantages, application conditions, and economic efficiency of several technologies (single hydraulic props, mobile hydraulic supports, and lightweight mechanized mining systems) applied to thick, gently inclined seams, along with their potential future applications, were conducted in detail. The results of the study highlight the advantages, challenges, arising issues, and solutions encountered during the implementation of lightweight mechanized mining technology at Mong Duong coal mine. Based on these findings, the author proposed several solutions for applying lightweight mechanized mining technology to thick, gently inclined seams.
