A survey with the help of GPS or Lasers can help to create the contours within no time as compare to Total Station survey. No need of trained surveyors, even the junior staff with the gadgets understanding or proper training can do the survey.
An orebody modeling project starts with a critical review of existing drill hole and surface or underground sample data as well as maps and plans with current geological interpretation. Drill hole and/or sample databases are set-up to suit all the quantitative and qualitative information necessary to build a resource model.
The time value of money plays an important role here. Simply put, the annual profits generated by a mine must be sufficient to pay back (within a reasonable time) the money invested in the mine. It is the job of mining engineers to estimate the ”payback period” in what is called a feasibility study.One of the important elements in a feasibility study is the estimate of mine operating costs.
MINE DEVELOPMENT Sequence of operations
The sequence consists of defining the benches, motorable haul roads, slope strengthening, dewatering points throughout the leased years, quantities from the benches, step by step mining for the life of the mine.
SUPERVISION & MONITORING Adhering strictly as per the Plan
Whatever has been planned or estimated on paper has to be proved or executed on site, So supervision & monitoring becomes the key role. Proper benching, maintaining the haul roads in motorable slopes, side walls stabilizing & maintaining the dewatering points to ensure the smooth working even at the time of monsoon.
The executed work has to be updated in the CAD drawings to understand the further plan.
