气囊固定式新型顶板离层仪的设计思路

Design idea of new roof separation indicator with fixed airbag

顶板离层是巷道围岩变形和破坏的主要形式之一,当顶板离层超过一定范围,顶板就会处于非稳定状态,极易发生顶板事故。顶板离层仪是有效监测顶板运动的仪器,根据顶板离层的测量原理,结合现场实践经验,创新性地提出了采用气囊固定与微变形软管连接的柔性接触式顶板离层仪的设计理念,为弥补不足和发展离层仪提供了新思路。

The roof abscission layer is one of the main forms of roadway surrounding rock deformation and damage, when it exceeds a certain limit, the roof is in an unstable situation and will very easily result in accidents. The roof separation indicator is an instrument that can effectively monitor roof movement. Based on the measuring principle of roof abscission layer and practice experience, the design idea of soft-contact roof separation indicator with fixed airbag which connect with micro-deformation hose is put forward creatively, a new idea that compensating the shortage and developing the roof separation indicator is provided.
