Description/Abstract:
This report details post-Piledriver Re-entry. Re-entry down the Piledriver shaft went slowly. The shaft collar had bounced so high and hard that there was a separation directly under the collar and approximately 30 feet vertically of shaft wall in that area spalled off and fell into the skip Docket. The collar area had to be packed with new concrete prior to advancing further downshaft. Drilling, sampling, gas analysis, and radiation monitoring activities are detailed.
