According to the failure mechanism,the analysis of supporting in soft-rock roadway and,the concept of initiative supporting,the authors have make a theoretical analysis of the technologically and economically effective practice with bolt-grouting reinforcement at-420m main return way on East-Four mining area in Pansan Colliery.

Combining on-the-spot actual measurement with numerical calculation,the authors have discussed the deformation laws and failure features of floor lift in soft-rock roadway,which would help to solve the problem of soft-rock roadway supporting.

Based on the soft-rock roadway of Enhong colliery in Yunnan province,this paper analyzes by nmuerical simulation the three supporting plans for soft-rock roadway junctions.

Several support methods of soft rock tunnel;

Research on the controlling parameters for smooth blasting in soft rock tunnel;

Research on nonlinear mechanics design method of bolt-net-anchor coupling support for deep soft rock tunnel;

Failure cause and pressure behavior law of soft rock laneway in deep mine;

Discussion on the transfiguration mechanism and the control technology of soft rock laneway;

The extreme soft rock laneway have the characteristic of continuous plastical deformation destroying.

Through strduing a vast amount of practices for supporting roadway in soft rock this paper introduces supporting feafure of roadway in soft rock,development and present situation of supporting rockway in soft rock in our country it raises safety supporting counfermeasure of roadway in soft rock and some problems.

A new concept and technique was developed to reinforce roadway in soft rock by combining external roof bolting with internal grouting.

Study on the deformation law in the complete service stage of roadway in soft rock based on rheological analysis
