    NO PRIORITY TARGET MEASUREMENT

    1 Geotechnical &

    Hydrological Drilling

    1. Geotechnical holes are to identify and

    collect subsurface information (soil &

    rock) to support slope stability analysis.

    2. Dewatering holes are to identify

    groundwater characteristic and reduce

    groundwater pressure behind pit wall.

    2,000 meters of core

    drilling at SMO, BMO, LMO

    and PMO site and 600

    meters of soil drilling.

    1,500 meters of vertical

    drain hole (VDH) drilling atSMO, BMO and LMO site.

    2 Monitoring System

    Improvement

    1. Extensometer installation with alarm

    system for slope stability monitoring

    (ground surface movement)

    2. Inclinometer Installation for slope stability

    monitoring (ground subsurfacemovement).

    3. Vibrating Wire Piezometer (VWP)

    installation for groundwater pressure

    monitoring.

    To be installed 1 unit at

    SMO at the middle of 2012

    To be installed 1 unit at

    BMO at September 2012

    To be installed at SMO,LMO and BMO. 3 holes for

    each site at October 2012.

    3 Improve

    geotechnical logging

    data base

    1. giNT software acqusition for geotechnical

    logging data base.

    To be started at the middle

    of April 2012.
