摘　　要：在总结爆破理论和实践研究基础上,探讨了巷道掏槽爆破的作用机理,简述冲击波、应力波和爆生气体在掏槽爆破中的作用,并分析了岩石性质、炸药性能、设计计算和施工工艺4方面对巷道掏槽爆破效果的影响。详细分析了岩石应力应变特性、斜眼和直眼掏槽设计、爆速等因素,提出了应力应变特性和岩石性质与炸药性能匹配对掏槽的重要影响,并根据4方面的影响因素总结和提出了一些实际操作建议。Based on the summarization of the blasting theory and practices study, the paper discussed the function mechanism of the mine roadway slotting blasting and stated the functions of the shocking wave, stress wave and blasting gas in the slotting blasting. The paper an- alyzed the rock properties, explosive performances, design calculation and construction technique affected to the results of the mine road- way slotting blasting. The paper in detail analyzed the rock stress and strain features, the slotting design with the inclined borehole and straight borehole, blasting viscosity and other factors and provided the important influences of the stress and strain features, rock properties and explosive performance matching to the slotting. According to the above four influence factors, the paper summarized and provided same actual operation proposals.
