“Z型折返式”过斜巷中较大断层的研究

STUDY ON INCLINED ZIG-ZAG ROADWAY PASSING THROUGH LARGE FAULT

斜巷中过较大断层时 ,上、下山掘进不得不终止而采用后石门开拓或平石门联接 ,形成两段式运输的不利局面。本文通过空间解析几何学的方法 ,探讨了一种斜巷过较大断层的新方案。从整体上来看 ,斜巷过断层时两次转向 ,巷道布置在由三个平面组成的空间曲面内 ,但坡度一直保持不变 ,呈“Z型折返式”。该方案较好地解决了由于采用后石门开拓和平石门联接所引起的两段式运输问题。

In the case that inclined roadway passes through large fault,the upward and downward drivage has to stop,and the back crosscut development or flat crosscut linkage have to be adopted that cause unfavorable two stages haulage.To solve this problem,a new conception of inclined zig zag roadway passing through large fault and its mathematic model has been introduced.
