This paper analyzes on the possibility of adopting the anchor line suspended monorail hoist runway, and designs and develops the hanger of the anchor line suspended monorail hoist runway, which solves the problem of the erection of the monorail hoist runway in the transportation adopting the monorail hoist in the ground coal road stage with the total bolt support.

This paper introduces the application of roofbolt-reinforced corbel beam-metal net-anchorage cable joint supporting technique on ground coal road, including its supporting method, construction technique, mining pressure monitoring and implementing results.

he anchor bolts support pattern is mainly employed successfully in the seam floor roadway while its more broken surrounding rock is acted by the dynamical compressive force and high tectonic stress, and some deformation regularities of the roadway under the complicated stress condition are obtained by using the finite element numerical methnod.

New development of rock bolting technology for coal roadway in China;

Dynamic and informational rock bolting design method for coal roadway and its application;

Numerical simulation and industrial test of boreholes destressing technology in deep coal tunnel;

After summarizing the working experiences and study results,this article has proposed a plate supporting technique with anchor bars in coal tunnels.

The research shows that there are great difference in permeability coefficent with the flow method of one way and radius way in coal tunnel.
