As an active support component that goes deep inside the rock mass and can change some mechanical properties of the rock mass, the mechanical essence of the bolt is to use the friction effect between the bolt and the surrounding rock to limit the…

As the semiconductor industry approaches the physical and material limits of traditional scaling, the demand for energy-efficient, high-performance devices has intensified. Among the promising alternatives, Tunnel Field-Effect Transistors (TFETs)…

Stress–strain curve

The deviatoric stress-strain curves of the rock samples are show in Fig. 6; experimental results show that confining pressure is a critical factor affecting the strength and deformation of rock samples. Under the same…

The use of aluminum and aluminum alloys are rapidly increasing in the various fields and manufacturing industries because of their lightweight properties and high strength-to-weight ratio with good corrosion resistance. In aerospace and defense,…

In this paper, we propose an electricity purchasing and selling decision model for load aggregators in China’s dual-tier electricity market environment, as shown in (Fig. 1). The model consists of two main components: an electricity purchase…

Initially, walkable equipment (egg-laying machines) used for producing blocks was employed. The main system structure of the machine relied on simple mechanical drive methods, and the vibration system mostly used small, attached vibrators common…

The methodology of this paper, written for the assessing of carbon–neutral supercapacitors in renewable energy systems, includes self-improving agent-based molecular fuzzy intelligent algorithms. The steps of the self-improving agent-based…

Creation of a numerical calculation model

This time, the ANSYS/LS-DYNAMIC program is used to simulate the tunnel blasting excavation. The parameters of the peripheral eye have a considerable influence on the damage to the surrounding rock and the…

Structure characteristics of samples

The catalytic effects of metal chlorides on coal surfaces may be thoroughly and informatively investigated using scanning electron microscopy (SEM). The morphological properties of both raw and chemically…

Description of soil in the study area

The Ula Ulo open pit slope comprises three distinct layers of silty-clay to clay with low plasticity soils. The natural moisture content of the slope materials varies between 17.57% and 26.19%. Additionally,…
