随着矿井逐渐转向深部开采，软岩巷道底臌控制已成为制约部分矿井安全开采的关键。以2204工作面为研究对象，采用现场实测方法确定了该工作面软岩回采巷道围岩变形特点，并结合现场实际分析了引起该巷道底臌的主要因素。提出散水治理、注浆锚杆底板加固和底板浇筑混凝土等方式对该巷道进行底臌控制，结果表明该方法可有效对底臌进行控制，具有较好的实践和推广意义。
隨著礦井逐漸轉嚮深部開採，軟巖巷道底臌控製已成為製約部分礦井安全開採的關鍵。以2204工作麵為研究對象，採用現場實測方法確定瞭該工作麵軟巖迴採巷道圍巖變形特點，併結閤現場實際分析瞭引起該巷道底臌的主要因素。提齣散水治理、註漿錨桿底闆加固和底闆澆築混凝土等方式對該巷道進行底臌控製，結果錶明該方法可有效對底臌進行控製，具有較好的實踐和推廣意義。

With the gradual shift deep mining ,floor heave controlling of soft rock roadway has become a key part of restricting safety mining in some mines .Taking 2204 working face as research suject ,the paper determined surrounding rock deformation characteristics of soft rock roadway by site measuring ,analyzed the main factor caused by roadway floor heave combined with site practice ,and put forward floor heave controlling methods of a‐pron treatment ,grouting bolt floor reinforcement and pouring concrete on floor ,etc ..Results showed that the method was effective for controlling floor heave and had good practice and promoting significance .
