5.药量计算 (1)单孔装药量单孔装药量可按下式计算: C=0.35k_BK_lK_pAh~s式中C——单孔装药量(公斤); K_B——取决于破坏程度的系数。松动、预裂、切割爆破时,取0.8～1.0;要求碎块散离原位时,取2～3; A——材料抗力系数(见表5); K_f——临空面修正系数(见表6); K_p——爆破厚度B修正系数。B<0.8米, K_p=0.9/B;B≥0.8米,L_p=1。表5 材料抗力系数A值 5. Dose calculation (1) Single-hole charge Single-hole charge can be calculated as follows: C = 0.35k_BK_lK_pAh ~ s where C - single hole charge (kg); K_B - depends on the destruction The degree of the coefficient. Loose, pre-splitting, cutting blasting, take 0.8 ~ 1.0; Requires fragmentation in situ, take 2 to 3; A - Material resistance coefficient (see Table 5); K_f - Pro face area correction factor Table 6); K_p - blasting thickness B correction factor. B <0.8 m, K_p = 0.9 / B; B> 0.8 m, L_p = 1. Table 5 material resistance coefficient A value
