摘　　要：唐口煤矿采用立井开拓方式,分区开拓,分区通风。因主通风机通风阻力逐渐增大,通风负压达到3 564.6Pa,在井田南部需开凿进风井、回风井各1个。两井筒均穿过第四系、侏罗系F2断层破碎带及富水基岩,涌水量较大,决定第四系和侏罗系破碎带段采用冻结法施工;基岩富含水层段采用钻孔泄水,普通法施工,双层素混凝土井壁结构,确保井筒安全高效施工。A mine shaft development mode,block development and block ventilation was applied to Tangkou Mine.Due to the ventilation resistance of the main ventilator was steadily increased,the negative pressure of the ventilation reached at 3 564.6Pa.An air income ventilation shaft and an air returning ventilation shaft were required to be sunk in the south part of the minefield.Both shafts would pass through the Quaternary and Jurassic F2 fault broken zone and watery base rock.The water inflow was high and a ground freezing method construction was applied to the Quaternary and Jurassic broken zone section.A borehole water leakage,the conventional method construction and a double concrete shaft liner structure were applied to the watery section of the base rock in order to ensure the safety and high efficient construction of the mine shaft.
