Characteristics of Underground Warehouse and Concrete Wall Formed by Synchronous Blast Enlargement Method
S. S. Peng · Journal of China University of Mining and Technology · 2001
The ultimate principle of forming underground warehouse and concrete wall by the method of synchronous blast enlargement was expounded,and its characteristics was analyzed on the basis of experiments. The results show that larger warehouse bulk and condensed range in soil, better physical and mechanical properties of soil, and better mechanical performance of concrete can be obtained by this method under the same conditions, compared with the normal blast enlargement method. Meanwhile, this method synchronizes blast enlargement with support successfully.
