Abstract

Diorite mining activities have the potential to cause environmental degradation. Therefore, there is a need for reclamation. Reclamation is part of environmental control in implementing Good Mining and Operational Practice. One of the stages in the implementation of reclamation is the arrangement of post-mining land. The soil arrangement system is divided into 3 (three) systems, namely the soil leveling system, the guludan system, and the pot system. Land management system based on top soil needs. Therefore, this research aims to analyze the land management system and determine the optimal topsoil stocking system. The method used in this research is a qualitative method of analysis. Data processing uses AutoCAD 2021 software and ArcGis 10.8 software. The cross-sectional method is used in data processing to determine the availability of topsoil and topsoil in the study area. The results obtained in this study are (1) The planned area of the reclamation area is ± 5.29 hectares; (2) The overburden stocking volume is 35,397.56 LCM; (3) The volume of distribution of topsoil using the land leveling method is 13,387.96 LCM.

Abstract

CV. Artha Agung Bersama is an andesite mining company that uses a blasting system. This mining activity can harm workers if they do not apply good K3 management in blasting activities. One of the hazards of blasting activity is flying rock. For this reason, it is necessary to identify potential hazards, assess the level of accident risk, and recommend risk control efforts. The method in this study is the HIRAC (hazard identification risk assessment and control) method. This activity has five potential hazards: broken drum straps, worker negligence, explosive sounds, fly rock, and workers walking in a hurry in locations with a lot of gravel. There are five risks of accidents from potential hazards: being hit by a drum, scratched hands, pinched fingers forming a critical cover, slipping, exposure to diesel fuel, hearing loss, and being hit by a rock. Of the five hazard risks, three risks are included in the priority one category, namely: scratched hands, pinched fingers forming key covers, slipping, exposure to diesel fuel, and being hit by rocks. One risk is included in priority category three: being hit by a drum. One risk category is very high, namely being hit by a rock. The recommended risk control hierarchy for blasting activities is engineering control, administration, and personal protective equipment.
