Through adpting U-steel bolting with wire mesh in 21 dip of Lugou coal mine,condition of roadway supporting is improved,technological and economic results are gained.

And the concrete tests show that the application of the steel belt and anchor net support obtains good results in NO.

As for the coal mining roadway with bolt support,it's the most dangerous that the roof usually falls because roof bedding separation value is too large.

This article tells us the rationalism of coal drift bolting with wire mesh and achievements in technology spread.

With the continuous development of bolting with wire mesh support theory and the advance of the equipments,tool and materials,the construction craft is more and more perfect,and more appliles in the different tunnel cross section.

Combined with the experiences of developing roads, direct cuts and the cutting roads of comprehensively mining work face, the author made researches on the acting mechanism of metal net by adopting bolt net support test.

The entries in complicated geological conditions are categorized and discribed,whose bolt and mesh support technique is analysed,some reazonable measures are put forward.

It has preasented the technology in the tail and main gate of the face 1106 and bolt and mesh support and some problems involved in the above metioned.
