The resonable support way is pointed out in order to reach the purpose of reducing roadway support cost.

This paper introduces a kind of design thinking for roadway support combined theory with practice.

The roadway support which is affected by many kinds of factors in soft rock is a complex systematic problem.

Application of bolt connecting chain in tunnel support under complex geological conditions;

Since the complexity and uncertainty, static design used for underground engineering is inadvisable, so dynamic informative design for tunnel support is introduced.

Though the load analysis on the tunnel roof wall-rock in the fault footwall tunnel, this paper solves the problem of the tunnel support of tunneling through the great fault; and though the load analysis on the corresponding wedge of the lower abandoned tunnel, solves the problem of the influence of the lower abandoned tunnel on the upper tunnel floor.

Optimal design of roadway supporting system in soft rocks based on structural reliability;

Research and application of fly ash spraying concrete in roadway supporting;

So, it's very important to logically design the roadway supporting in extended engineering of No.

Application of a new plastic expanding metal anchor in stoping tunnel supporting;

Feasibility research of tunnel supporting in JinChuan harmful rock;

Aimed to Tunliu Coal Mine complexed deep high stress drift support,they unceasingly analysised bolt support multidate information design and and control science support way,choose rational support form and parameter,this has very important meaning to ensure coal mine safety and high efficiency production.

In accordance with the characteristic of burst-prone ground in the deep hard-rock mines, the basic principle is discussed of drift support under the lower rockburst condition.
