雅店井田水文地质特征及井筒防治水措施

Hydrogeological Characteristics and Prevention Water Measures of Yadian Coal Mine

雅店煤矿采用立井开拓方式开采,主、副、风3井筒均采用局部冻结法施工,基岩段施工中3井筒均有涌水,井筒涌水严重威胁矿井安全。采用工作面帷幕注浆、增大临时排水系统、壁后注浆及施工封水帷幕等措施,有效地封堵了工作面及井筒涌水,保证井筒安全,顺利掘砌到底,为类似矿井的水害防治提供了经验参考。

Yadian shaft were treated coal mine shaft used to develop ways of mining, the three main and auxiliary, wind with partial freezing method construction, the bedrock section construction in wellbore were gushing, wellbore inflow seriously threatens the mine construction. The face curtain grouting, the temporary drainage system, the posterior wall of the grouting and construction of water sealing curtain method increases, effectively blocking the work surface and borehole water inflow to ensure wellbore safety, smooth driving and masonry in the end, which provides reference for similar mine water disaster prevention and control.
