中深孔爆破参数优化试验研究
Experimental study on the optimized blasting parameters for medium-depth hole
摘要
Abstract
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.关键词
