To reach this depth muons should have the energy at the sea level greater than 1.3 TeV. The muon charge ratio was defined using the number of the decays of stopping positive muons in the LVD iron structure and the decays of positive and negative muons in scintillator. We have obtained the value of the muon charge ratio ${k}$ ${= 1.26 \\pm 0.04(stat) \\pm 0.11(sys)}$.","authors_text":"A. Molinario, A.S. Malgin, A. Zichichi (LVD Collaboration), B. Miguez, C.
