| Abstract: | Chaohua Coal Mine of Zhengzhou Coal Industry Group belongs the typical "three soft" instability coal seam.Through the undergrand pressure observation to the blasting and caving coal face,its behavior and characteristics are understood. Thereby the supports stability is analyzed.The measures of roof management is pointed out.Not only the difficult problems of roof management are effectively solved,but also the safe production of coal face is realized. |
