Research and Application of Shallow Sampling Technology in Shallow Overburden Area of Grassland

Abstract:

To quickly expose shallow overburden areas of grassland and minimize the damage to environment, the shallow drilling sampling technology was used to expose the Quaternary and take the eluvial slope and bedrock layer samples, for geochemical exploration of metallic minerals shallow drilling, geochemical stereoscopic mapping and trenching replacing. A combination of shallow drilling sampling techniques in the shallow overburden area of arid and semi arid grassland was developed. The application of this method in Hua'aobaote leadzinc mine and Dongwuqi area show that through flexible and reasonable adjustment of drilling equipments and drilling process, the target layer sampling should be smooth.

Key words:shallow drilling; sampling technology; shallow overburden area; shallow geochemical exploration drilling
