2.1.1.1. Exploration
The things required to paid attention in activity of exploration such active effort permission, having mine technique head mining inspector, exploration
program and equipments, socialization of exploration plan, compensatory of farm, drilling, laboratory analysis, finishing required maps like map of geology, map of
contour, soil layer map, isopach map, geology report, and reporting to governmental institution Suyartono, 2003.
2.1.1.2. Stipulating of Reserves
The Reserve is specified into reserve predicted and reserve proven. According to Suyartono 2003, reserve predicted is resource of established and
some of mineral resources measured which was storey; level confidence of geology still lower so that economically, mining activity can be done. While
proven reserve is mineral resource measured which pursuant to mine feasibility study, all relevant ness factors have fulfilled, so that mining can be conducted
economically.
2.1.1.3. Geo-technique Study
According to Suyartono 2003 for the agenda of mining planning method and system and also the election of correct appliance, hence needed study of geo-
technique for purposing of determining bevel stability, ramp design, excavability, blasting design, dig step estimation, dig dimension and design, strength of dig
materials and ore, entering hole design, heap design of waste, studying of bevel trouble. As for some activities which need to be conducted in knowing
characteristic of geo-technique area with activity covered by inside testing,
laboratory analysis, mapping, study of crack, influence of water, condition and geology of hydrology.
Some studies of geo-technique which was often conducted in mining industry for example: analysis and monitoring of bevel stability, audit of risk
analysis and geo-technique, buttress audit and design, model and characterization of rock period rock mass, and surface stabilization of land; ground, geo-
technique criteria for design mine and study of geo-technique for feasibility study.
2.1.1.4. Hydrogeology Study
