| Abstract: | Based on specific ore-rock feature in the Iron mine, test is made by improved middle-long hole blasting with blasting results as expected. Analysis is made of the action mechanism of burden to long-hole bottom spacing,hole bottom reversed blasting and multiple-row equal-level short delay blasting for effective improvement of ore-rock blasting efficiency. |
