The latest development of the explosion accident at the Wucalong gold mine in Qixia, Shandong: mobilize multiple resources to rescue the shaft to 350 meters underground

　　As of 12:00 noon today (January 16), the latest progress of the rescue is as follows: More than 90 sets of rescue machinery and equipment have been added to the scene, with a total of 357 sets of various types of machinery and equipment.

The rescue team consists of 13 professional teams and 1 fire fighting team, with 439 rescuers.

A total of 6 boreholes were arranged for rescue. The completed footages were: No. 1 borehole (diameter 311mm) 570m, No. 2 borehole (219mm) 420m, No. 3 borehole (diameter 219mm) 521m, and No. 4 drill The hole (diameter 711mm) is 400 meters, the No. 5 hole (diameter 350mm) is 201 meters, and the No. 6 hole (diameter 311mm) is 64 meters.

The clearance depth is 350 meters.

　　As for the expert team, an expert team composed of more than 30 people from the Mine Rescue Center of the Emergency Management Department, Beijing Mining and Metallurgical Group, China Coal Fifth Construction Co., Ltd., Shandong Gold Group, Shandong Energy, Shengli Oilfield, etc. was established to conduct on-site research and judgment to guide rescue plans .

Rescue force: successively mobilized the mine rescue team of Longkou Mining Group Co., Ltd., the mine rescue team of Zibo Mining Group Co., Ltd., the militarized mine rescue team of Yanzhou Coal Industry Co., Ltd., the rescue team of Zhaoyuan Jindu Mine, and the Laizhou Mine of Shandong Gold Rescue Team, Non-Coal Mine Rescue Team in Muping District, First Exploration Team of Shandong Coalfield Geology Bureau, Second Exploration Team of Shandong Coalfield Geology Bureau, National Mine Emergency Rescue Team, Geological Special Exploration Team, Shandong Geological and Mineral Bureau Sixth Geological Team , Shandong Zhaojin Geological Exploration Co., Ltd., Hebei Retrograde Emergency Rescue Technical Service Co., Ltd. and other professional rescue teams and Yantai City Fire Detachment stationed on the scene to carry out rescue work.

In terms of machinery and equipment: With the strong support of the Emergency Management Department and the Ministry of Transport, the most advanced international drilling rigs were mobilized from Yulin, Shaanxi, Huainan, Anhui and other places, opened a green channel, and rushed to the site day and night to carry out drilling operations.

　　The geological conditions of the accident site are complex and changeable.

One is that the mineralized zone of the gold mine is located in the fault, and the broken stratum is easy to "stick" and affect the drilling progress.

Second, the joints and fissures of the rock formation are relatively developed, which makes the boreholes easy to deviate.

Currently, individual deviation drilling is being corrected.

The third is that there is a lot of water in the drilling, and the introduction of water into the tunnel will cause danger to the trapped personnel.

Fourth, the surrounding rock near the ore body is mostly granite, with very high hardness, which causes slow progress.

　　The Emergency Rescue Headquarters stated that it always puts the people first and life first, and does everything possible to fight against the clock and exhaust all means to rescue the trapped miners. (Headquarters CCTV reporter Dou Xiaolei)
