Precision blasting technology was studied based on classification of rock mass blastability aiming at slow drift advance by blasting in stope and high unit consumption of explosive in Xincheng Gold Mine. By analyzing indices such as uniaxial compressive strength, rock mass integrity coefficient and rock density, a blastability classification model with multi-parameters was established, and the rock mass blastability was divided into 5 levels based on the proposed modified BQ index formula. It is found the ore rocks in Xincheng Gold Mine are mainly rated as level Ⅲ (intermediate) and level Ⅳ (difficulty) in terms of ore blastability, for which blasting parameters were then optimized respectively. Industrial experiments show that after optimization, the blasthole utilization rate for stope drifts was increased from 87.3% to 93.9%, and overbreak was reduced, including the over-width down from 17.5% to 1.25% and the over-height down from 25.0% to 3.3%. It is shown that smooth blasting and precise control of surrounding rock disturbance can be actualized.

针对新城金矿采场爆破进尺不足、炸药单耗过高等问题，开展基于岩体可爆性分级的精细化爆破技术研究。通过分析岩石单轴抗压强度、岩体完整性系数及岩石密度等指标，构建多参数融合的可爆性分级模型，提出修正的BQ指数公式，将岩体可爆性划分为5级。结果表明，新城金矿矿岩以Ⅲ级（中等可爆）和Ⅳ级（难爆）为主。基于分级结果，对中等可爆与难爆岩体分别进行爆破参数优化。工业试验表明，优化后采场进路炮孔利用率从87.3%提升至93.9%，超宽由17.5%降至1.25%，超高由25.0%降至3.3%，实现了光面爆破与围岩扰动精准控制。
