摘要
针对14采区辅助运输巷掘进过正断层期间,受上覆砂岩含水层影响,导致巷道掘进过程中顶板淋水大,顶板支护质量差等技术难题,北辛窑矿通过技术研究,决定对巷道淋水区域顶板采取注浆锚索支护,在提高锚索全长锚固的同时,对顶板裂隙岩体进行粘接填充,从而达到有效堵水的目的。实际应用取得了显著成效。
Due to the influence of overlying sandstone aquifer during the driving of auxiliary transportation roadway in No.14 mining area through normal fault, which leads to the technical problems such as large roof drenching and poor quality of roof support, Beixinyao Mine decided to adopt grouting anchor cable support for the roof of roadway drenching area through technical research to improve the full-length anchoring of anchor cable, and at the same time,glue and fill the roof fractured rock mass to achieve the purpose of effective water plugging. Through the practical application effect, remarkable application effect has been achieved.
