This study looked into how hydraulic support could get crushed in coal mines due to concentrated coal pillars. By analyzing a specific mining accident in Shigetai Mine, the researchers found that as the mining machine went through a 5 to 20-meter area with lots of coal pillars, the ground above the pillars would break and create an unstable structure. This could cause sudden pressure and lead to the hydraulic supports getting crushed. To prevent this, the researchers recommend things like blasting the pillars beforehand and adjusting the mining direction. Following these suggestions could help reduce the risk of support crushing accidents in fully-mechanized coal mining operations.
