For a multi-shot drillhole survey, you need:- The SmartTool 1 SensIT in hole probe {NO film, batteries or cables } 2 StoreIT pocket data pad {NO stopwatch or notes } 3 An office PC with the MeasureIT and DisplayIT software Some Running Gear 3 Shock sub, pressure barrel &aluminium sinker bars 4 Wireline, rods, pipe or rope to run SensIT into the hole Drillsite Details 5 Hole reference and measurement depth Operating the FLEXIT MultiSmart
1 Switch ONStoreIT 2 Use SETTINGS to enter:- Hole reference number Start station depth (say, 250m) Station depth interval (say, 6m) Survey direction (say, up) 3 Press DATAto confirm entries 4 Press NEW to startSensIT,using the radio chip 5SensIT is now taking a reading every 5 secs Start the survey with the StoreIT data pad
1 Place SensIT in the pressure barrel, supported by the spring hanger 2 Lubricate O-rings. Tighten threads by hand 3 Tong up running gear threads 4 Run SensIT to survey start station depth; hold it still. Preparing SensIT for running into the hole 3 x 1.5m aluminium spacer bars Totally sealed SensIT probe Spear-type landing collar Top sub assembly Bottom sub with shock assembly
1 Switch ONStoreIT 2 Screen will show 3 Press & hold OK until StoreIT peeps. Taking the first shot with StoreIT Depth 250 m (start depth) Press OK Measuring Wait ..5 secs (counting down)
1 Wait until StoreIT peeps again and screen shows 2 Move SensIT up 6m to the 244 m station 3 Press and hold OK until StoreIT peeps. Taking the next shot with StoreIT Depth 244 m(start depth-6m) Press OK Measuring Wait ..5 secs (counting down)
During a survey use SETTINGS to:- Change station depth Change station interval Redo or duplicate a station End the survey Start a new survey while SensIT is down the hole Continuing the survey with StoreIT
1 Use SETTINGS to:- 2 Press and hold OK until StoreIT peeps. 3 Pull running gear out of the hole, remove SensITfrom pressure barrel & place within 10m of StoreIT. Completing the survey with StoreIT End Survey? Press OK
1 Use SETTINGS to:- 2 Press & holdOK until StoreIT peeps. 3 Wait until download is complete 4 Switch OFF StoreIT Transfer data from SensIT to StoreIT End Session? Press OK Downloading Record No. # (counting)
Download data from StoreIT to a PC 1 Connect TransITaerial to your PC serial port 2 Switch ON StoreIT 3 Run MeasureIT software; click Download 4 The radio link and software do the rest!
Quality Check system guarantees results • Checks for tool movement • Checks for magnetic disturbance • Allows you to delete or adjust unreliable readings • See the MagIC presentation
A tabulation for each station of up to 17 measurements. Choose only the ones you want. A true plot of the hole in plan, E/W or N/S sections Choose the scale, colours, marks, grid spacing Any number of holes, collar extension on/off Supplementary data plotted against hole path Max/min hole separation Exported to any other software How would you like to see the results?
Note: Four degree change in dip over first 2 metres Remainder of hole is relatively straight. Total error of 1.13 metres (6%) at 16 metres depth Some typical readings from a “vertical” hole
Borehole interference in Civils projects • Surveying will prove the integrity of reinforcement programs • MeasureIT warns you when hole separation exceeds set limits It’s so simple with FLEXIT
Six inclined grout holes are collared at 150 deg. to allow for known RH deviation; see 2, 4 & 6. Unfortunately 1, 3 & 5 hadn’t read the script! Displaying hole paths on a PC
