第聂伯罗彼得罗夫斯克矿业学院研制了一种堵充填料的轻便式充气挡墙,主管部门在盖斯克采选公司地下矿对其试验样件作了验收试验。轻便式充气挡墙,可封闭断面为4～8米~2的水平巷道,以防止充填矿房内的充填料涌入作业区。在结构上,挡墙由一些长软气包堆置构成,封闭巷道的整个断面。软气包的堆置是长边与巷道中心线平行。为保证作业区內不渗入充填料,在接触充填料的挡墙表面包上不透水的帆布。为了提高挡墙的承载能力,每层软气包都安上横梁。挡墙靠软气包与巷道壁的摩擦力固定在
The Dnepropetrovsk School of Mines developed a light inflatable retaining wall packed with packing material. The competent authorities conducted an acceptance test on the test samples at the underground mine in Geski Mining and Dressing Company. Light inflatable retaining wall, can be closed section of 4 ~ 8 m ~ 2 horizontal roadway to prevent the filling of the filling material in the mining house into the operating area. Structurally, the retaining wall consists of several long flexible gas packs that enclose the entire cross-section of the roadway. Soft gas package pile is the long side of the roadway centerline parallel. In order to ensure that there is no infiltration of filling material in the work area, a watertight canvas is wrapped on the surface of the retaining wall that contacts the filling material. In order to improve the carrying capacity of the retaining wall, each layer of gas bag are placed on the beam. Retaining wall fixed by the friction of soft gas bag and roadway wall
