A log-file name, a time- or depth-interval and parameters to be logged are selected from a menu.The system produces files in ASCII format, which can be transferred into several Windowsprograms for further analyses.The following parameters are automatically registered: date, time, mode, status, rotationpressure (bar), feed force on drill bit (kp), feed force on cylinder (kp), feed pressure (bar),flushing water flow rate (L/min), flushing water pressure (bar), rotation speed (rpm), penetrationrate (cm/min), drill length (cm), bit position (cm), feed position (1/10 mm), rod weight (kg) androd pressure (bar). The parameter “mode” represents the current activity in the drilling cycle,whereas “status” gives an explanation to drill stops and also indicates when a drilling sequenceis finished.For the geoscientific data acquisition, the following technical parameters are of primary interest:• time,• drill bit position,• penetration rate,• feed force,• rotation speed.However, during drilling of the telescopic boreholes at Forsmark, the registration is extended toinclude also the following flushing water parameters:• electric conductivity,• dissolved oxygen,as well as the return water parameters:• flow rate,• electric conductivity.The system is also provided with devises for convenient sampling of flushing water and returnwater for analysis of the Uranine content.Finally, the level of the groundwater table in the borehole is registered during drilling.3.3.4 Equipment for deviation measurementsDuring drilling of borehole KFM06C, deviation measurement were made after completed drilling,in order to check the straightness of the borehole. The measurement was performed witha Reflex MAXIBOR system, which is an optical, i.e. non-magnetic, measurement system.Azimuth and dip are measured at every third metre. The collaring point coordinates and themeasured values are used for calculating the coordinates of the position of the borehole at everymeasurement point.Also another method, based on magnetic accelerometer technique, was applied for deviationmeasurements in order to check the validity of the MAXIBOR-measurements. The surveyinginstrument used was the FLEXIT Smart Tool System. However, only the results of theMAXIBOR-measurements are presently in use-flagged in SICADA, see Section 5.4.9.3.3.5 Equipment for hydraulic tests, absolute pressure measurementsand water sampling during drilling in KFM06CIt is stated in <strong>SKB</strong> MD 620.003 that hydraulic tests, absolute pressure measurements and watersampling should be performed at certain intervals using a down-hole tool specially designed forthe wireline-76 system. The tool, which is denominated “the wireline probe” or “WL-probe”, isdescribed in <strong>SKB</strong> MD 321.002, see Table 1-1.21
