Abstract
Limestone behavior under explosive loading was investigated. The behavior of the limestone by the action of the three types of explosives, including granular, ammonite and emulsion explosives was studied in detail. The shape and diameter of the explosion craters were obtained. The observed fragments after the blast have been classified as large, medium and small fragments. Three full-scale experiments were carried out. The research results can be used as a qualitative test for the approbation of numerical methods.
Highlights
Impact and blast threats exist in a wide range of engineering, security and defense sector
Maximum dimensions of the cloud debris reached in the full-scale test 1, but minimum dimensions of the cloud were in the full-scale test 3
Fragments of limestone after the explosion were classified as large, medium and small fragments
Summary
Impact and blast threats exist in a wide range of engineering, security and defense sector. It was detail studied of river ice and limestone under explosion. The main results should be considered as measured by the diameter of the craters of explosion and lanes, the crater depth, the diameter of the debris cloud. The subject of research is the state of limestone after the explosion, including the shape of the crater and so on.
