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.

Under the low stress and soft-broken state of rocks,the convergence between roof and bottom of tunnel in soft-broken coal seam is taken as the index to evaluate the result of bolt-mesh supporting.

Discernment and optimization on the key parameters of bolt-mesh support in the crushed soft roadway

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.

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.
