Management and Analysis of the Surge of Digital Data for Injection Measures

If one considers an injection campaign for sealing fault zones in tunnelling with regard to the quantity of data obtained, one has to reckon with up to 500 injection points daily, or with, for example, three injection passes per metre and not infrequently 50 advance injection boreholes per round. Assuming a drilling depth of only 20 m, this already results in 3000 injections. For drilling and injection, equipment is used that records numerous measured values and parameters, such as different pressures and flow rates as well as rotation speed. Calculated briefly, this means that for an average 30-minute injection alone, more than 5000 measured values are recorded and processed. That adds up to an incredible 1 000 000 readings for a comparatively conservative 200 injections. Every day. And this flood of data only concerns the logged series of readings from the injection operations. In addition, drilling data or, for example, construction process data, signs of wear and reactions of the rock also contribute to the accumulation of data.
