Abstract
The underground mining method is the activity that leads to the surface impacts caused by subsidence movements. The mining Vietnam industry is developing, and step by step, applying advanced technologies to practical production in order to improve mining efficiency. Because of safety issues, optimal exploitation of mineral reserves, and reduction of losses are always the top priorities in mining companies of Vietnam. The paper assesses the ability to utilize the sources of ash and slag from the thermal power plant as backfilling material for underground mining activities in the Mao Khe coal mine, Vietnam. This technological solution helps to release a large amount of ash and slag discharged from the plants and minimizes negative impacts on the environment. Besides, the use of backfill methods also increases the stability of the safety bank and decrease coal losses during the exploitation process in underground coal mines in Vietnam.
In this study, the authors performed theoretical and experimental researches with the hydraulic transport method using the materials with various ratios of water and ash in the field. The results were recorded and statistically analyzed to select the most suitable materials that are applicable at the southern wing area of The Mao Khe coal mine.
