Study Reveals Insights on Digging Anchor Machine Stability

An in-depth analysis has been conducted on the stability of a digging anchor machine and the wear patterns of its tracks under digging conditions. The study focuses on the dynamics model of the digging anchor machine and its interaction with the roadway floor. By utilizing advanced simulation techniques like the discrete element method (DEM) and multibody dynamics (MBD), researchers have been able to simulate the cutting process of a full coal seam and coal rock containing gangue by the digging anchor machine.

The research findings shed light on the cutting depth of the digging anchor machine drum, the sliding distance of the track, and the stress-strain patterns of the roadway floor. The study also delves into the wear characteristics of the track shoe under different conditions. The results provide valuable insights into the control and reliability of the digging anchor machine and offer a theoretical basis for predicting the life fatigue of its tracks.

The historical context of the study lies in the longstanding issue of balancing digging speed and mining speed in coal mines. The introduction of comprehensive excavation equipment like digging anchor machines has brought about new challenges regarding stability and impact on roadway floors. By analyzing the motion characteristics and stability of the digging anchor machine under various geological conditions, researchers aim to improve the safety and efficiency of coal mine operations.

The study draws from a rich body of research on vehicle terramechanics and track-ground interactions. Previous studies have focused on the dynamics of tracked vehicles under various conditions, highlighting the importance of accurate modeling for predicting ground pressure distribution and driving resistance. The current research extends this knowledge by specifically examining the behavior of digging anchor machines in underground coal mine environments.

Through detailed modeling and simulation, the study provides a comprehensive understanding of how digging anchor machines interact with the surrounding environment. By considering factors like cutting depth, track wear, and floor deformation, researchers are able to offer practical insights for optimizing the performance and durability of these machines. The findings are expected to have significant implications for the mining industry, helping to enhance operational efficiency and safety.

Overall, the analysis of digging anchor machine stability and track wear under digging conditions represents a significant contribution to the field of mining equipment research. By leveraging advanced simulation techniques and drawing on established knowledge in vehicle terramechanics, the study offers valuable insights that can inform future advancements in mining technology and equipment design.
