Abstract

Abstract: With characteristics of poor anchoring effect and serious deformation, the soft rock tunnel of coal mine has affect the stability of the whole structure seriously. Taken the soft rock of the chamber of Xiahuo Coal Mine as the test point, spray bolting and grouting support design was done. Through site mine pressure monitoring, application effects of bolt-grouting support was tested and expectation effects reached.

Key words: Soft rock, Surrounding rock control, Bolt-grouting support, Mine pressure monitoring
