On Jan 10, 2021, 22 people were trapped underground after an explosion at the Qixia Hushan gold mine in Yantai, Shandong province. The whole rescue operation is facing three major problems: the mine is deep, the rock is hard, the difficulty of the rescue is world class.
On the evening of January 19, after receiving the notification from the Ministry of Emergency Management of the People's Republic of China, academician Manchao He immediately organized the Chinese Society for Rock Mechanics and Engineering (CSRME) to set up a field rescue group. The expert group is headed by Academician Manchao He and consists of Professor Chunming Zhu, Professor Qi Wang, Professor Jun Yang, Professor Jiping Liu, etc.
The expert group proposed a scientific judgment that the wellbore blocking is the partial suspension congestion mode, clarified the composition structure of debris and loose compressible characteristics, solved the problem of determining the state of the accumulation, and then put forward an optimization scheme of extrusion expansion repair taking the advantage of the compressibility of loose deposits (no need to clean the ascension blockage). This scheme provided scientific ideas and technical guidance for effectively solving the problems such as difficulty, slow speed and difficulty in lifting obstacles.
On January 24, the ventilation shaft rescue channel was successfully opened, and 11 surviving miners were successfully lifted out of the shaft. Shandong Provincial Party Committee and Provincial Government sent a thank-you letter to Academician Manchao He, and Shandong Province Hushan Gold Mine Explosive Emergency Rescue Headquarters awarded a silk banner of "remember life first, unite the power of Hushan rescue" to the expert team of CSRME led by Academician Manchao He.
This rescue operation fully demonstrated the social responsibility and mission of researchers from the CSRME, which focused on high-tech and accurate help, scientific rescue and life saving.
