<p>Aiming at the problem of uneven energy distribution caused by fan-shaped medium-deep hole blasting under the condition of immediate proximity to faults, the research on the characteristics of blasting energy distribution and precise control technology has been carried out. Taking the fan-shaped medium-deep hole mining under a fault in a mine in Shandong as an engineering background, LSDYNA numerical calculation was used to establish a numerical model connecting the fault and the surrounding rock by the ‘CONTACT’ method. The influence of factors such as fault dip angle and thickness on the spatial distribution of blasting energy in medium-deep hole stope is analyzed. With the increase of fault dip angle, the barrier effect increases gradually, while the superposition effect shows a nonlinear change of first increasing and then weakening. When the dip angle is in the middle range (35 ~ 45), the stress superposition in the footwall area is the most significant. When the fault thickness increases, the barrier effect and superposition effect of faults are significantly enhanced. Based on this, the differential medium-deep hole control technology under the influence of fault is put forward, which regulates the inter-row differential parameters of burden and intra-row differential parameters of hole spacing of the fault affected area. When the burden increases by 0.10&#xa0;m and the hole spacing increases by 0.20&#xa0;m, the energy of fault affected area can be adjusted to achieve the blasting effect under the original blasting parameters without fault. The results of this study can provide quantitative basis and theoretical support for blasting design in fault area.</p>
