Gypsum industry news

China: Four miners were rescued from a collapsed gypsum mine in Shandong Province on 29 January 2016 after 36 days trapped underground. About 1000 people have been involved in the rescue efforts, complicated by falling rocks, unstable geological structures, water outbursts and carbon monoxide leaks, according to the Xinhua news agency. The rescue was made after a 220m shaft was drilled to the trapped miners.

One miner died in the accident on 25 December 2015, while 11 were saved immediately after the incident, according to the report. Thirteen miners are still missing. The owner of the mine committed suicide by jumping into a flooded shaft after the accident and several executives of the mine are under police investigation.

China: A 190m borehole is being drilled to rescue four trapped miners from a Gypsum mine in Shandong. It is the fifth hole that has been drilled by the rescuers since the accident happened on 25 December 2015. The hole will be used as an escape passage for the four miners, according to China Radio International.

"Now the drill work has reached the layer of red sandstone, nearing the mine roadway. Everything went well on overall. We overcame the difficulties when drilling previous layers, and now it's the final sprint. The layer of red sandstone is as thick as 30m," said rescue worker Sang Jingqiu.

When the drilling is finished, rescuers will send down a rescue capsule to the miners in the underground tunnel. Rescuers have been able to pass food and other vital supplies through an emergency hole.

When the mine collapsed 29 miners were working underground. Apart from the four trapped miners that have been located, 11 have escaped or were rescued, one is confirmed dead and 13 remain missing.

China: Rescuers have dropped provisions to four Chinese mine workers trapped for 10 days in a wrecked gypsum mine and are slowly drilling a route to save them, according to Reuters.

The men are trapped more than 200m below the surface and state media has reported that they are in good condition. Because the ground is so fragile, the rescuers managed to drill only 25m deep after more than 40 hours. Rescue leader Du Bingjian said that he could not give a time when the men would be pulled up. The mine collapse on 25 December 2015 in Shandong killed at least one person. 13 others are missing and 11 made it to safety or were rescued earlier.

China's mines have long been the world's deadliest, but safety improvements have reduced deaths in recent years. In 2014, some 931 people were killed in mine accidents in China, drastically down from the year 2002, when nearly 7000 miners died.
