The researchers explored ways to prevent powered support failures in coal mines by studying the behavior of mine strata pressure in coal pillars. They focused on a specific mining face in a mine and found that problems occurred when the face passed through concentrated coal pillars above it. The issues arose due to a combination of factors like roof instability and large weight shifts. To tackle this, they recommended adjustments in the mining process, such as controlling face tilt and optimizing cutting height, to enhance support resistance and safety valve function. By implementing these measures, they aimed to avoid accidents and ensure safe mining operations.
