Application and cost analysis of green exploration technology in geological core drilling

The implementation of green exploration in Qinghai Province has both ecological and economic benefits. Based on the method of combining theory with practice, the vegetation coverage area, one of the four representative landscape areas in Qinghai Province, is selected as the research object, and the representative mining area is selected. The basic principles and specific construction process of three processes which have great influence on the surface vegetation in the geological core drilling construction process are summarized The basic principles and specific construction process of mud optimization, drilling fluid recovery and waste management are summarized. The economic benefits of green exploration geological core drilling and conventional geological core drilling are compared and analyzed. Compared with conventional exploration method, the personnel cost of green exploration mode is increased by 44.2%, material cost is increased by 18.1%, and total cost is increased by 121.5% The comparison of the cost of exploration mode and green exploration mode can provide parameter support for the preparation of budget standard in the next step.
