Drilling Well Method. Drilling well method is to excavate a shallow well at a certain place of the material pile to obtain the sample. After that, we should take a portion of the sample to do sample division. For this reason that the material is loose, the well wall should be supported when sampling, so the workload is large and the cost is high.
