During Phase I (first 18 months) the project is segregated into four areas of reporting: (A) Grout Formulation, (B) Grout Characterization, (C) Water Quality Monitoring, (D) Subsidence Control & Contaminant Transport. The first component involves formulating a grout mixture with appropriate flowability and strength (flow and strength requirements will be set by other components) to be used in filling complex mine voids. The Grout Characterization component will determine the flowability characteristics of the formulated grout and model the flow of the grout filling the mine void. The Water Quality component involves background monitoring of water quality and precipitation at the Phase III (Longridge) mine site. The last component involves evaluating the strength requirements and the migration of contaminants through the candidate grouts. This report separately discusses progress on all components of the program in order of project subtask. The subtasks are arranged according to the Network Diagram on the following pages. Progress for each subtask can be seen in the Gantt Chart following the Network Diagram.
