Effect of support pore size on integrity of Al_2O_3 micro-filtration membranes;

Reasearch on a New Type of Anodic Alumina Membrane Supported by Aluminum;

Study on resistance to erosion of cordierite and alumina supports

Measures of mining the full height by adding the length of single prop once;

Depending on this instrument, the fault can be noted in time by detecting the pressure of the single prop uninterrupted.

In order to research support technology of gob-side entry retaining under limestone roof,according to the characters of large flap top and slow subsidence for limestone roof,the paper established the roof cutting mechanical model of gob-side entry retaining and designed quantitatively the support parameters for untied roof cutting of anchor and single prop.

Research on anti-pulling mechanism in soil-nailing supporting system;

Application of grid and net pouring concrete supporting system in the construction of tunnel;

Generally,its supporting system belongs to temporary support,in many situations,it relies on experience and so it is often ignored.

Design method and technical features of monitoring system with higher performance,developed recently for checking sealing quality of single hydraulic props are stated in this paper.
