Tämän diplomityön tavoitteena on selvittää korreloiko Measurement While Drilling -data (MWD-data) kalliolaadun ja räjäytystulosten kanssa. Lisäksi tavoitteena on luoda MWD-dataan perustuva menetelmä räjäytystulosten ennakointiin. Onnistuneella räjäytystuloksella tässä yhteydessä tarkoitetaan, että katkon räjäytyksen jälkeen tunnelin profiili katkon kohdalta on suunnitellun mukainen. Tutkimuksessa MWD-dataa kerättiin YIT Rakennus Oy:n Niittykummun louhintatyö-maalta kahdella Atlas Copcon porajumbolla. Dataa analysoitiin Underground Manager -ohjelmassa, johon luotiin työkohteeseen sopivat asetukset hyödyntämällä vertailuaineistoa. Vertailuaineistona käytettiin louhintaurakan tilaajan, Länsimetro Oy:n, tarjoamia geologien kartoitustuloksia ...
