Our survey team was officially established in 2018, primarily responsible for surveying tasks at rescue sites involving landslides and collapses, warning of secondary landslide risks, ensuring the safety of rescue personnel, and providing real-time data support for on-site command. Over the past six years with the team, I have traveled over 200 days each year, solving hundreds of slope technology issues for more than 100 open-pit mining enterprises across the country, accumulating a wealth of experience. We have participated in emergency rescue operations in harsh environments like high temperatures, humidity, severe cold, snowstorms and high-altitude oxygen shortages. Using self-developed slope radar equipment, we closely monitor the risk of slope collapses at rescue sites, providing over 5,000 hours of safe monitoring, and ensuring the safety of nearly 3,000 rescue personnel.
