钻爆法施工石灰岩围岩巷道单位炸药消耗量的确定

Determination on Unit Explosive Consumption of Drilling and Blasting Method Construction for Limestone Surrounded Roadway

单位炸药消耗量是设计爆破图表的重要参数,论文分别以相关参数计算方法、定额查表法和逐个布置计算法研究了钻爆法施工石灰岩围岩巷道的合理炸药消耗量,结果表明,石灰岩围岩巷道单位炸药消耗量范围为1.987~2.7kg,该研究可为施工材料消耗定额的合理确定提供相关依据,供同类工程施工借鉴参考。

Unit explosive consumption is an important parameter for the design of blasting chart, the paper studied the reasonable explosive consumption in borehole - blasting method construction of limestone surrounded roadway, respectively using relevant parameter calculation, quota look - up table method and arrangement sequence calculation. And the results show that the explosive consumption is in the range of 1. 987 -2. 7kg. The study could provide basis for the determination of material consumption quota and provide references for similar projects.
