Blasting in the ocean tunnel has a great impact on Marine life and seabed vegetation, so it is necessary to control the impact of blasting vibration on the surrounding Marine environment. In this paper, taking Xiamen Tunnel as an example, the blasting vibration response characteristics of undersea tunnel are studied, and the velocity attenuation ru...

In cases where blast vibrations cannot be measured with seismographs, empirical formulas are commonly used to predict vibration by specifying the peak particle velocity (PPV)-scale distance (SD) relationship. A new approach that provides important information about the relationship of seismic waves generated by blasting with rocks is the seismic qu...

The excessive destruction of surrounding rock in deep tunnel will change the original environmental state and destroy the natural ecological balance. Research on the dynamic response characteristics and damage thresholds of rock masses in deep environments plays a crucial role in determining the excavation range of blasted rock and establishing saf...

Analysis of slope stability due to blasting based on the pseudostatic principle is considered too conservative because the slope receives a constant maximum seismic load (and hence constant acceleration) without considering the duration of the blast. In reality, the acceleration fluctuates with time and eventually diminishes. One method to analyze ...

Real-time monitoring of rock stability during the mining process is critical. This paper first proposed a RIME algorithm (CCRIME) based on vertical and horizontal crossover search strategies to improve the quality of the solutions obtained by the RIME algorithm and further enhance its search capabilities. Then, by constructing a binary version of C...

The paper is focused on steel surface processing to ensure an improved adhesion of applied powder layer. Mechanical pre-treatment, chemical pre-treatment and their combination were used to compare their results with each other and to find out the pre-treatment that affected the final outcome the most. The final score was determined by the grid meth...

To ensure that large precision instruments and equipment are in the best working condition, it is necessary to provide a suitable working environment for them. At this time, there is a high requirement for the vibration of the foundation at the location. Measuring the foundation vibration parameters, analyzing the foundation vibration state, and ta...

The drilling and blasting operation represents an important component of the whole complex of operations specific to the activity of exploitation of mineral resources through explosives blasting, both economically and in terms of environmental impact. The extraction activity requires the preparation of a complex document called drilling and blastin...
Tato diplomová práce se věnuje problematice mechanického tryskání povrchu, jejím základním principům, rozdělení, popisu tryskacích zařízení a abrazivům. Experimentální část je zaměřena na testování různých parametrů vysokotlakého vodního paprsku (tlak, doba tryskání) vhodných k čištění povrchu.

Ground vibration induced by blasting operations is considered one of the most common environmental effects of mining projects. A strong ground vibration can destroy buildings and structures, hence its prediction and minimization are of high importance. The aim of this study is to estimate the ground vibration through a hybrid soft computing (SC) me...
