Abstarct: One of the most critical stages in mining operations is selecting an appropriate extraction method for the mineral deposit. Choosing the right method for underground mines is crucial for the economic viability, safety, and operational execution of exploiting mineral reserves. Once a mining method is selected, replacing it with another is often problematic, as it can be so costly as to render the entire project economically unfeasible. The objective of this project is to select a suitable underground mining method for inclined coal seams. To this end, the technical and economic feasibility of implementing the Inverse Stope Mining Method at the Gomaneh Coal Mine has been investigated. At the Gomaneh Mine, considering certain conditions and using the UBC method, the Longwall Mining Method had been previously selected. Therefore, in this thesis, the Inverse Stope Mining Method has been implemented for this mine, and its technical and economic advantages and disadvantages have been examined. baxsed on the economic evaluations of this mine, according to the criteria mentioned in this thesis, it was determined that the Inverse Stope Mining Method is more suitable in terms of production and efficiency compared to the Inclined Longwall Mining Method and is proposed for replacing the Inclined Longwall Method at the Gomaneh Mine. Economic calculations show that in the Inverse Stope Method, 1.63 tons of coal are extracted per person, which is a 122.5% increase compared to the Longwall Method. Support costs increased by 1483%, equipment costs by 203%, depreciation costs by 192.5%, and annual operating costs by 1209%. Considering a 327.3% increase in the number of workers in the Inverse Stope Method and a 400% increase in annua l extraction, the gross profit at year-end increased by 232%.
