煤炭建设井巷工程消耗量定额》(2007基价)总说明第二十八条规定：本定额斜井(巷)、平硐(巷)及硐室掘进定额是按爆力为320cm3的硝胺炸药制定的，使用不同爆力的炸药时，可按下列炸药爆力系数调整定额炸药使用量：(5分)
Q1=eQ0
e=320/V
式中： Q1——调整后定额炸药用量， kg
Q0——定额硝胺炸药用量，kg
e ——炸药爆力系数;
320——定额采用硝胺炸药的爆力，cm3;
V——施工采用水胶炸药的爆力，cm3
现已知一巷道掘进套用的定额子目为2192，定额中硝铵炸药的消耗量为154kg，实际施工中采用暴力为220 cm3的乳化炸药，现要掘进该巷道920m3，请计算所需乳化炸药的定额消耗量。
