Determining Methods for Minimum Burden of Large-Aperture Rock by Contrdled Blasting

摘要：

The essay has established the formulas of minimum burden about Large-aperture controlled blasting of rock according to the theoretical calculations and analysis of cylindrical charge explosion stress field and in combination with the rules of rock breakage under the explosive load. With better results achieved, the formulas have found wide application in the concrete engineering practice.

关键词： large-aperture controlled blasting minimum burden, explosion stress field
