摘　　要：Traditional surface exposure methods,such as trenching and exploratory shaft sinking,have their own limitations and do harm to the environment.Thus,shallow drilling was applied in geological mapping to expose shallow orebody and to determine the thickness of top soil layer,and then to illustrate bedrock lithology and geological boundary.It can also help to study geological structures and to reveal the orebody shape,and further to combine with rock core sampling and chemical analysis to develop the systematic method of drilling instead of trenching technology.Traditional surface exposure methods,such as trenching and exploratory shaft sinking,have their own limitations and do harm to the environment.Thus,shallow drilling was applied in geological mapping to expose shallow orebody and to determine the thickness of top soil layer,and then to illustrate bedrock lithology and geological boundary.It can also help to study geological structures and to reveal the orebody shape,and further to combine with rock core sampling and chemical analysis to develop the systematic method of drilling instead of trenching technology.
