Blasting demolition plays an important role in building demolition, and numerical-simulation methods can facilitate the optimization of blasting-demolition schemes. To study influence delay-time differences between columns on blasting effect small-aspect-ratio reinforced concrete structures, a separated common node model structures was established through finite element numerical simulation sof...

Blasting is one of the primary aspects mining operations, and its environmental effects interfere with safety lives property. Therefore, it essential to accurately estimate impact blasting, i.e., peak particle velocity (PPV). In this study, a regular random forest (RF) model was developed using 102 blasting samples that were collected from an open granite mine. The inputs included six parameter...

The research aims to investigate the failure characteristics of rock caused by blasting under high stress, explore energy generation and its transfer release in effects blasting. Physical experiments numerical simulations were performed. results showed that, as with AE time-series data, attenuation time activity increases number events, thereby decreasing overall stability samples. In terms spa...

The existence of karst cavities has an important impact on the safety foundation pit excavation projects. It is engineering guiding value to study influence blasting process pits and how optimize stiffness cement mortar improve effect. Based bench project Shenzhen Dayun Foundation Pit Project, this paper adopts SPH-FEM coupling calculation method cavities, cavity-filling water silt clay rock-bl...

In this paper, a control system in the domain of teleoperated service robots is presented. A reference architecture ACROSET has been analyzed and designed following a concurrent object modeling and architectural design methodology that uses UML as describing language. The architecture of the whole system has been implemented in a blasting robot for ship hullsGOYA –using Ada 95 and GLADE. Our pr...

The new Austrian tunnelling method (NATM) and tunnel boring machine (TBM) are methods for excavating underground spaces. NATM construction has noise vibration problems, excavation using TBM the disadvantage of high initial cost is limited by ground conditions. A parallel been developed to overcome these limitations. However, research on lacking, it crucial identify applicability in advance appl...
