Research on design of advanced solutions for tunnel support by anchors at maingate of longwall IV-4-17 Khe Cham II-IV mine of Ha Long coal company

Abstract

Implementing the national science and technology project code 010.21.CNKK.QG/HĐKHCN, based on research in developed countries on tunnel anchoring such as Russia, China and assessing the situation of anchoring in underground coal mines in Vietnam. Mining Advanced Technology Support Center has cooperated with "RANK 2", Russian to deploy advanced solutions in supporting the tunnel with anchors in the maingate of longwall IV-9-17, Khe Cham II-IV mine, Ha Long Coal Company - TKV. Advanced solutions are applied in 03 main stages: Survey of geological conditions of the area; Design of tunnel support with anchors; Online monitoring of tunnel stability.
