The series of BCF samples based on 14 different basalt deposits was obtained under equal conditions. The tensile strength of the fibers from different deposits varies in the range from 1495 to 3380 MPa. Based on the literature data about 32 natural basalt continuous fibers with different compositions and experimental data about 14 obtained BCF series, the dependence of the tensile strength of the filaments on the acid modulus and the NBO/T parameter was calculated. The PCC (Pearson correlation coefficient) value of the NBO/T and the tensile strength was 0.79, for acidity modulus and tensile strength - 0.53. Thus, the correlation between the structural parameter and strength is higher than the correlation between the acidity and strength modulus.
