摘　　要：为了消除塔山煤矿四盘区副立井掘进过程中底板奥灰突水的潜在威胁,对副立井井底水窝奥灰水害进行探查、注浆改造和加固治理,在井筒周围共设计施工了17个钻孔,其中,16个钻孔终孔位置分别对称均匀布置在井筒外30 m范围和奥灰含水层下30 m。探查结果表明,井筒东南部奥灰含水层富水性大于井筒西北部,裂隙发育东南也较西北强。注浆结果表明,注浆后出水量、吸水率均远小于注浆前,且注浆后吸水率均小于标准值0.01 L/(min·m·m),表明煤层内裂隙已达到充填加固封堵的作用。In order to eliminate the hazard of water inrush from the floor of the auxiliary shaft in the fourth panel of Tashan Coal Mine during excavation,the Ordovician limestone water hazard of the auxiliary shaft bottom water pit was investigated,grouting transformation,and reinforcement treatment were carried out.A total of 17 boreholes were designed and constructed around the shaft,of which 16 boreholes were symmetrically and uniformly arranged within a range of 30 meters outside the shaft and 30 meters below the Ordovician limestone aquifer.The exploration results indicate that the water abundance of the Ordovician limestone aquifer in the southeast of the shaft is greater than that in the northwest,and the development of fractures in the southeast is also stronger than that in the northwest.The grouting results indicate that the water output and water absorption rate after grouting are much lower than before,and the water absorption rate after grouting is less than the standard value of 0.01 L/(min·m·m),indicating that the cracks in the coal seam have been filled,reinforced and sealed.
