Underwater blasting safety measurement device and underwater blasting safety measurement method

Abstract

The embodiment of the invention provides an underwater blasting safety measurement device and an underwater blasting safety measurement method, which relate to the field of underwater blasting projects. According to the device and the method of the invention, when a first propagation medium parameter, a second propagation medium parameter and a height difference factor are initialized, the height difference factor can be used for correcting the first propagation medium parameter and the second propagation medium parameter; when the actual to-be-measured mass point vibration velocity parameter is calculated according to the first propagation medium parameter, the second propagation medium parameter and the height difference factor after actual initialization, the actual charge weight parameter, the actual blast center distance parameter and the actual height difference parameter, errors between the actual to-be-measured mass point vibration velocity parameter obtained through calculation and the actual to-be-measured mass point vibration velocity parameter are greatly reduced, and when the actual to-be-measured mass point parameter obtained through calculation is compared with a standard safety vibration velocity parameter range, the outputted result information is more reliable and practical.

Description

technical field [0001] The invention relates to the field of underwater blasting engineering, in particular to an underwater blasting safety measuring device and method. Background technique [0002] During the construction process of underwater blasting, the seismic effect of underwater blasting is transmitted from the bottom of the water to the land, but due to the shock wave in the water formed by the explosion, it will have a certain impact on the vibration of the bottom of the water. The structural vibration effect under the action of underwater blasting is more complicated than the impact of rock and soil blasting on land on geological structures. Generally, low-frequency and high-frequency waves act together. The main characteristics are that the vibration frequency is wide, the high frequency is rich, and the vibration is large. During drilling and blasting operations, the huge energy generated by the explosion acts on the surrounding rocks, and the shock wave genera...

AI Technical Summary

Problems solved by technology

Due to the error between the particle vibration velocity measured by the blasting vibrometer and the actual particle vibration velocity, there is a certain error in the actual values ​​of K and α, which leads to errors in the judgment of whether the location of the target building is safe.
