Based on the experiment by using split rockbolt support at Peifeng Mine Yanwu +35m-21#,Fujian Coal and Electricity Corporation,the paper proves that split rockbolt support in developing entry has advantages over the traditional support and other rockbolt supporting types.

Application of slit weldge tubing bolt in Jinshan Glod Mine;

For supporting the broken roof of the stope of mechanized operation and its upper wall which comes into contact with fault plane,the tubular friction bolt is employed in Xincheng Gold Mine.

This paper provides the expeditious construction method in rock heading under the complicated geographic conditions at Anhui Wobei Coal Mine Project in respect of steel support (advance split-tubes and beam support),construction equipment (rock drill on airfeed leg,slusher,etc),construction process and organization plan.

The article has introduced the supporting technology with slit wedge tubing bolt in siltstone roadway in Wufeng Colliery,which has solved the problems of top collaps and floor lift and proved effective in construction.
