Abstract: For the presence of seam deep-hole pre-splitting blasting multifactorial complex cases, in order to quantify the effect of blasting analysis, on the basis of deep-hole pre-splitting blasting in coal seam of No.2 coal mine of Zhaogu, the approach of using AHP-Fuzzy mathematics method is presented to establish comprehensive evaluation mathematical model on the effects of Deep-hole pre-splitting Blasting. The blasting safety, technical equipment, economic benefits and influence factors are taken as the first level indicators and 13 factors such as blasting vibration, blast hole punching, pure gas drainage volume and coal hardness and so on as the second level indicators. Through effects verification evaluation of deep-hole pre-splitting blasting in coal seam, rating a score of 85.67, the result is good. Also discussed the impact of ground stress and coal hardness and other factors on blasting effect, the evaluation findings are consistent with the actual effect.
