| Abstract: | The top coal of 6223-2 working face was fractured by fault and higher slice mining in Haishiwan coal mine, in order to improve the stability of top coal, Grouting reinforcement technology had been adopted.Scientific grouting holes arrangement mode had been studied and reasonable grouting parameters were determined according to the site conditions by the method of theoretical analysis. The results show that the effect of grouting reinforcement is remarkable, there is not large area of leakage in the working face during mining period. |
