为了提高矿山的实际生产效率和经济效益，在室内力学试验和标准抛掷爆破漏斗试验基础上，进行了能确定实际炸药单耗、排距、孔底距的试验和崩矿步距的正交工业试验，研究表明：炸药单耗选用0.981 kg/m3更为合适；运用正交试验来确定扇形孔的排距和孔底距是一种较为准确的方法，试验优化后的排距为1.6~1.85 m，孔底距为2~2.2 m；通过理论计算并结合现场工业试验确定最优的崩矿步距在4.8~5.4 m范围内为宜.

On the basis of indoor mechanical tests and normal cast blasting crater experiments , orthogonal industrial tests determining dynamite consumption , row spacing, hole bottom spacing and caving interval are performed to improve mining efficiency and economic benefit. Researches show that the optimal explosive consumption is 0.981 kg/m3. Orthogonal industrial test can establish row spacing (1.6~1.85 m) and hole bottom spacing (2~2.2 m) accurately. The optimal caving interval is 4.8~5.4 m through theoretical calculation and field industrial tests.
