Abstract: The "single roadway top coal mining method for steep and medium-thick seams" addresses the challenges posed by significant variations in seam dip angles and thicknesses. This approach segments the seam into multiple sections along its incline, with each section utilizing a single roadway aligned with the seam's trend. This roadway is dedicated to one coal mining section, managing the ventilation, transport, and pedestrian traffic for the working face. To ensure the effective execution of this method, numerical simulations are employed to examine the surrounding rock movement after the working face advances. Two roadway preservation techniques are proposed, tailored to different burial depths: the "flexible mold concrete wall" and the "flexible mold concrete wall + right-angle tram I-steel roof." Both methods undergo theoretical analysis and numerical validation. Practical application demonstrates that these techniques effectively stabilize the surrounding rock, prevent airflow between the roadway and the gob, mitigate gas accumulation, and reduce the risk of spontaneous combustion in the residual coal. This method enables efficient single roadway top coal mining and offers crucial technical support for similar roadway support challenges, holding significant theoretical and practical relevance.

Abstract: Remote Terminal Unit (RTU) replacement is a complex, capital-intensive process that demands careful management to avoid operational disruptions and excessive costs. This study examines strategies to improve the efficiency and reliability of RTU replacements, focusing on a comprehensive framework that incorporates pre-execution testing, multidisciplinary collaboration, and attention to cybersecurity and environmental resilience. Insights from brainstorming workshops with IT, OT, cybersecurity, and network engineering experts emphasize the critical role of exhaustive pre-implementation testing to ensure compatibility with existing systems and reduce integration risks. Functional, performance, and security testing are essential for addressing potential failures, minimizing downtime, and safeguarding against cyber threats. Furthermore, the study highlights the impact of environmental factors on RTU durability, advocating for rigorous environmental testing and the selection of resilient RTUs designed to withstand challenging conditions. The proposed framework seeks to reduce risks, enhance reliability, and prevent costly disruptions by integrating technical, operational, and safety standards. By providing a holistic approach to RTU replacement, this work contributes to improving industrial system reliability, ensuring operational continuity, and enhancing the functionality of critical infrastructure. Practitioners can apply these actionable insights to achieve successful RTU replacements with minimal interruptions, fostering a more reliable and secure operational environment. Through collaboration and diligent planning, the study outlines a pathway to optimize RTU replacement processes, ultimately improving the resilience and efficiency of vital infrastructure systems.
