蒙西地区根据周边矿井及长城五矿实际揭露岩性情况,地层无较大地质构造,巷道内裂隙发育,易于形成导水通道。长城五矿主副斜井及矿井回风大巷在掘进过程中由于裂隙发育,迎头淋水不断,给施工带来很大困难,必须通过有效的注浆措施进行水害治理。本文重点通过对砂岩裂隙水防治技术研究,达到砂岩裂隙止水和加固顶板的作用。
According to the actual revelation of lithology of the surrounding mines and the Great Wall Minmetals in Mengxi area, there is no large geological formation in the strata and the fissures in the roadway develop and it is easy to form the aqueduct. In the tunneling process, due to the development of fractures, the main and auxiliary shafts of the Great Wall Minmetals and the return tunnel of the mine have been constantly pouring water, which brings great difficulties to the construction. Water treatment must be carried out through effective grouting measures. This paper focuses on sandstone fissure water prevention and control technology to achieve sandstone fissure sealing and strengthening the role of the roof.
