This paper introduced the cable anchor matching steel band technique to substitute the initial design at the circumstance of thick compound roof with the engineering example.

As a nursing theory is investigative and thorough to practice the empirical backlog with the united protection of bolt and anchor net and anchor wire in active entry,the protection technique,which bolt and anchor and anchor wire in active entry already had been applied in" three soft" coal seam,meanwhile the support of mine steel and U steel had been replaced by it with a good result.

The technology of combination of bolting wire mesh and cable anchor has been proved to be workable in permanent roadways,based on analysis of date collected from observations of roadway.

The technology of combination of bolting wire mesh and cable anchor has been proved to be workable in the permanent coal-seam roadways,basing on analysis of dates collected from observations of roadway.

By analyzing the case of using cable anchor and reinforcing bar pillars joint supporting technique to pass large fault in 6138 tunnel,the paper has introduced four sides such as the existing problems of cable anchor supporting,the decision of anchor supporting parameter,the construction demands of cable anchor and reinforcing bar pillars joint supporting and its applied effects.

This paper introduced the cable anchor support technology under the situation of compound roof for Yongxia mining area, analyzed the principle of anchor rod with cable anchor, and made a declaration for the support parameters.
