The ground support for the Ban Houayxai exploration decline project has been thoughtfully designed, leveraging a wealth of research alongside detailed geological and geotechnical mapping of the underground conditions. While the drilled holes presented some unexpected results in the decline area, our dedicated team has made remarkable strides in collecting valuable data through meticulous underground geotechnical mapping. This essential information has positively influenced our ground support design.Recognizing the complexities of the ground conditions, we are well-equipped to enhance our systems to maintain the safety and stability of our operations. This proactive approach underscores our team's extensive experience and strong observational skills. As we progress through the exploration phase, we are committed to continuously refining our techniques, which will foster greater confidence among our stakeholders regarding the project's potential. The data we gathered will empower us to integrate numerical analysis into our planning, establishing a robust foundation for developing improved strategies and more effective ground support solutions. Our empirical research demonstrates that the safety factor for our design exceeds 1.2, ensuring that our ground support remains stable throughout the mine's operational life. This paper primarily focuses on the rock mass classification of the Q system and the rock mass rating, which are critical elements of our comprehensive analysis.
