چکیده مقاله:

The productivity of the quarry during the wet season heavily depends on how well the personnel adjusts to the mine's environmental conditions and management plans. The improvement of granite production through workers' impact identification and mining advancement decision-making in Ondo State, Nigeria, has been considered in this study. The rate of granite production and the factors influencing workers’ efficiency were assessed using a well-structured survey and descriptive-analytic technique. To improve the production rate, the Multiple Criteria Decision-Making (MCDM) technique was used to select the most productive pit depending on a number of key labor impact factors. Health and safety in employment, the energy crisis, market conditions and level of competition, on-site accidents, natural disasters, and language barriers were some of the factors identified as external influencer factors affecting mine labor efficiency in granite quarrying. Finally, using the criteria's significance through the inter-criterion (CRITIC) approach, the mine workers’ influence on production was estimated and utilized for the best pit selection. The result of the MCDM revealed that the five pits (Pit ۱, Pit ۲, Pit ۳, Pit ۴, and Pit ۵) had the following decision performance scores: ۰.۶۵۹, ۰.۶۱۷, ۰.۵, ۰.۵, and ۰.۵, respectively. This made Pit ۱ the best production pit to be considered during the rainy season. The optimal solution was validated with the ۲۰۲۱ production report. The report shows that production from Pit ۱ had the highest revenue of ۱۶,۰۰۰ Per annum, the lowest dewatering cost, and the highest production rate compared to the other four pits.
