Due to the steep and complex terrains in the southern mountain range, the complex construction area is the most thorny issues as different collection methods and equipment have to be used in different areas. For the first time, the project adopts a combination of mountain operation equipment and marine geophysical collection equipment. Every day, the workers fly between the mountains and the camp by helicopter, which not only saves travel time, but also provides a guarantee for the safety of the workers. However, reaching the top of the mountain means that the difficulties are only just beginning. The exploration workers also need to dangle in the steep mountains with the aid of a safety rope fixed on the top of the mountain, holding a steel drill in their hands. While climbing down the mountain, they have to bury the geophones into the designated position.

Every night, the team analyzes the bottlenecks for the day, discusses and adjusts the construction plan and arrangement in a targeted manner to ensure the overall orderly progress. In addition, the problems that occur on the site every day must be resolved within an hour. Wang Duohan, manager of the No 1 team says timely and effective collective decision-making is a powerful tool for steering the construction of the project. Preparations for the project began in August, and after 41 days, the field work was fully completed on Oct 28. Most employees chose to be transferred to desert projects to continue their work.
