| 摘 要： | 为了解决桃园煤矿二水平轨道大巷底鼓变形严重的问题,在大量现场调研基础上,得出了巷道围岩应力高、底板岩性差以及底板未采取支护是导致巷道底鼓严重的因素。基于从提高底板强度和整个支护结构体稳定性角度出发,采用钢筋梯子梁配合长1.5、2.5和3.0 m的锚杆组合支护大巷底板,锚杆间距1.1 m,排距0.7 m。矿压观测结果表明：采用分层组合锚杆支护技术后,二水平轨道大巷最大底鼓量不超10 mm,锚杆平均锚固力不大于30 kN,有效解决了桃园煤矿二水平轨道大巷的底鼓问题。

| Abstract: | In order to solve the serious floor heave and deformation problems in No.2 Level Railway Roadway of Taoyuan Mine,based on the great site investigations,the high stress of the roadway surrounding rock,the poor lithology of the floor and no support means to the floor were the factors to cause the serious floor heave of the mine roadway.Based on the view to improve the floor strength and the stability of the whole support structure,the steel bar ladder beam and the bolts with a length of 1.5 m,2.5 m and 3.0 m ... |
