Special Issue Information

Dear Colleagues,

(1) Introduction, including scientific background and highlighting the importance of this research area.

Intelligent mining is the current direction of the high-production and efficient development of coal mines, just as rock formation control constitutes the core of safe mining in coal mines. With the increase in mining intensity and mining depth at the present, the geological conditions of mines tend to be complicated. Intelligent mining can realize the automatic operation of mines with complex conditions, reduce labor intensity and improve the safety of mining through intelligent identification, intelligent perception and intelligent control. Intelligent identification technology, equipment and systems are the keys to realizing intelligence. The movement of rock strata is the inducement of various disasters in the mine, such as mine pressure, water inrush, gas migration, etc. How to effectively control the movement of rock strata is a necessary factor to ensure the safe mining of the mine and can also be the guarantee to realize intelligent mine.

(2) Aim of the Special issue and how the subject relates to the journal scope.

The intelligent level can improve the production efficiency of mines, the strata control technology can ensure the safe production of mines, and the intelligent and strata control technology can realize the sustainable mining of mines.

(3) Suggest themes.

This Special Issue welcomes the submission of original research articles and reviews. Research areas may include (but not limited to) the following:

  • Intelligent monitoring technology;
  • Intelligent monitoring equipment;
  • Intelligent identification system;
  • Artificial intelligence algorithm;
  • Intelligent control system;
  • The law of strata movement;
  • Pre-splitting of strata movement;

Landslides result from weak surfaces with varying rock-soil properties, posing a significant concern for engineering and accurate deformation analysis. This study investigated the macroscopic physical and mechanical properties of paleo clay specimens during triaxial compression testing, aiming to elucidate the deformation mechanisms exhibited by these specimens under varying loading directions at both the loading and unloading ends, and numerical simulation methods were carried out to simulate actual engineering scenarios. The analysis encompasses deformation patterns, stress–strain relationships, Mohr stress circles, and numerical simulation failure cloud diagrams for soil samples under different loading directions. The results showed that the loading end of heterogeneous specimens exhibited noticeable deformations. Alteration of the loading direction induced variations in the failure mode. The position and size of the deformations for the only iron-manganese clay, loading end iron-manganese clay, and loading end reticulated clay samples changed with the clay layer at the loading end of the sample. Moreover, the stress–strain curves under different loading directions were different, with strain hardening and strain softening appearing in the two loading directions, respectively. The results of this study contribute to an in-depth understanding of the impact of the loading direction on the deformation and strength of paleo clay, thereby providing a foundation for landslide prevention and control measures.
