THE EDF GALLERY IN BELLEDONNE OR 18200 M OF WINDOWLESS TUNNEL. DRILLING BY THE TRADITIONAL METHOD AND THE SHIELD DRIVING TECHNIQUE

LA GALERIE EDF DE BELLEDONNE OU 18200 METRES SANS FENETRE - CREUSEMENT PAR LA METHODE TRADITIONNELLE ET CREUSEMENT PAR TUNNELIER

This report was presented at the Working Days of the Mining Section of SIM, in Biarritz, 10-14 May 1977. The author outlines the execution of the work which was divided into two sections: (1) for the upstream section the drilling method used was the conventional technique with blasting; (2) in the second downstream section the shield driving method was utilized. Details are given for each section of the rate of progress in good and bad terrain, and of the decompression phenomena and remedial measures taken. The advantages and disadvantages of the shield are discussed: progress speed, reduction in support and concrete linings, improvement in working conditions, but high purchase cost of the equipment and lack of flexibility.
