桃园矿10煤底板钻孔注浆堵水半径探讨

Discussion on grouting radius for blocking up water of No.10 coal seam floor, Taoyuan Mine

    摘要
  • 摘要: 桃园煤矿10煤底板裂隙发育不均匀,合理确定钻孔注浆堵水有效半径,是10煤安全开采的保障。经理论计算和实验研究,确定注浆有效半径为1015 m。

     

    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.
