| Abstract: | The fracture development of No. 10 coal seam in Taoyuan Mine is not uniform. The effective radius determination for block up water grouting is the key technique for safety producing coal seam No. 10. The theoretical calculation and actual study confirmed that the effective radius is about 10 - 15 m. |

| Keywords: | block up water grouting effective radius Taoyuan Mine |
