对工型承重柱拆除爆破布孔原理的探讨

Discussion on Design Principle of Hole Pattern for Demolishing I-Bar Pillars

本文从理论和工程实践两方面对工型承重柱拆除爆破的布孔原理进行了探讨，指出采用炮孔邻近系数m在2．5～3．5间的宽孔距法布扎，能够保证工型承重柱的准确倒塌。

The design principle of the hole pattern arranged for demolishing I - bar pillars wasdiscussed in practice and theory in this paper. It was showed that the ho1e pattern arranged with coefficient m of h0le spacing to hole burden in the range of 2. 5 ~ 3. 5 wasable to ensure the I- bar pillars fallen down.
