Associated with coal side support of thick seam,the authors have such study as structure,recipe and moulding craft of the new FRP bolt and find out the production key technology project of them.

The Infrared radiation experiments on FRP bolt in the process of loading were carried out.

FRP bolt is the ideal supporting material used for coal side.

Also presented is the actual application of this novel glass fiber reinforced plastic bolt in the #88301 coal face of Baode Coal Mine,Shendong Coal Company.

Nanshan mine roadway in accordance with its own characteristics,a district in the West fully mechanized coal mining face all eyes and orbit,transportation Lane had a new type of glass fiber reinforced plastic bolt Lane Lane for coal to help support the test,effectively reducing the cost of roadway support,enhanced safety,the use of effective,is of great technical and economic,security,efficiency.

Using template method to identify flaw signals in fiberglass-reinforced plastic sucker rod.;

Full-face pre-reinforcing method by fiberglass bolts can enhance the equivalent rigidity of the advance core soil and control the deformation of the advance core soil,so that arch effect can play its role naturally and assure the excavation safety.

This paper introduces the coring tools and technique of block six in Sudan,especially the structural features of coring which formation kept technique tool and fiber glass coring tool.
