The chemical consolidation technique and cable supplement support are adopted in the crossing roof to improve the bearing capacity of the whole bolt-rock support bod.

This paper expounds the mechanism of crossheading support on fully mechanized face,and sums up some advanced methods and successful experiences of applying cable supplement support in the practice.

High pretensioned stress and intensive cable bolting technology set in full section and application in entry affected by dynamic pressure

Fully utilize the intrinsic supporting system,fully utilize the loading capability of surrounding rock as the starting point,and refer to the geological condition,on the base of deeply practice、sufficiently demonstration and the intrinsic construction experience of anchorage cable,to optimize design parameters of anchorage cable reinforced supporting.
