摘　　要：以淮北煤矿项目为依托,通过理论推导出掏槽眼单孔装药量与单位体积药耗量的关系.结果表明:槽眼深度和岩石的普式系数对单位体积药耗量的取值有较大的影响,得出的试验规律对今后实际工程中这一参数的确定有参考意义.Based on Huaibei coal mine project,the relation between the charge amount of single hole in cut hole and the charge consumption per unit volume is deduced theoretically.The results show that the depth of cut hole and the general coefficient of rock have great influence on the value of unit volume charge.The test law obtained has reference significance for the determination of this parameter in practical engineering.

关 键 词：单孔装药量 单位体积药耗量 槽眼深度 岩性
