A structure design for temporary hydraulic support of tunnelling working surface
Abstract：It has been restricted the safety and efficiency of tunnelling working surface that the preceding support of tunnelling working surface in mechanized mine. Based on the summary of kinds of preceding support, this paper put forward a kind of technique plan of leading temporary creeping hydraulic support, it is whole new and has strong adaptability. This creeping hydraulic support is controlled by sequence valve. It can keep moving ahead along with mining roadheader driving. So this can realize parallel working between driving and support, both enhancing efficiency greatly and making sure safety.
