Large-equivalent-weight underground shallow-buried explosion effect simulating device

Abstract

The invention discloses a large-equivalent-weight underground shallow-buried explosion effect simulating device. The large-equivalent-weight underground shallow-buried explosion effect simulating device comprises a base, a container tank, a first vacuumizing device and an explosion source device, wherein the explosion source device comprises a glass cover, a detonating cord, a steel tube, a sealing plug, an electric detonator, an exploder and an air pressure adjusting device; the base serves as a supporting component of the whole simulating device, and is mounted at the bottommost end of the whole device; the container tank is mounted at one end of the base; the first vacuumizing device is connected with the container tank through a pipe; the glass cover and the electric detonator are positioned in the container tank; the bottom end of the glass cover is sealed through the sealing plug; the detonating cord is positioned in the glass cover, penetrates out of the sealing plug through a steel tube, and is connected with a conical end of the electric detonator; the other end of the electric detonator is connected with the exploder of the outside of the container tank; and the bottom end of the glass cover is connected with the air pressure adjusting device. By the simulating device, a large-scale throwing explosion effect simulating test under different parameter conditions can berepeatedly developed; and the simulating device is simple to operate and low in cost.

Description

technical field [0001] The invention belongs to the field of underground protection engineering construction and protection technology and engineering blasting research, and in particular relates to a large-equivalent underground shallow-buried explosion effect simulation device. Background technique [0002] With the successful application of various blasting technologies in the fields of transportation, water conservancy and hydropower engineering construction, energy and mineral resources exploration and development, and disaster prevention and mitigation of geological disasters, the scale of engineering blasting has continued to expand. At present, many engineering blasting schemes, especially the formulation of complex charge configuration schemes, are mostly based on geometrically similar empirical formulas, and a large number of blasting practices show that when increasing the scale of underground explosions, the gravity must be considered in the process of forming the...
