Abstract

The invention provides a manufacturing method of a compound material supporting plate, relating to a supporting plate for mine shafts and solving the problems of complicated technical process, low product strength, short service life and poor safety in the prior art. The manufacturing method comprises the following process steps: fully mixing 40-55% of short glass fiber, 30-45% of resin, 2-3% of mesotherm compound initiator, 1-3% of combined accelerator, 4-8% of defoamer and 5-15% of filling material in mass percentage with a mixer; loading the mixed materials in a die; spotting, and pressurizing and preserving heat; and opening the die, and ejecting out the compound material supporting plate. The compound material supporting plate is suitable for mine shaft and tunnel supporting, is simple to manufacture and has the advantages of high product strength, safe support and the like.

Description

technical field [0001] The invention relates to a support plate for mine shaft lane support, in particular to a support support plate of composite material. Background technique [0002] Mine shaft roadway support pallet is a device used as roadway support when mining underground mineral resources in mines. At present, there are mainly two types of supporting plates for mining: wooden and metal. Although wooden supporting plates are light in weight, they are perishable in the humid environment underground, have a short service life and consume more wood; although metal supporting plates are strong High, but the disadvantages are: (1) It is easy to rust under the wet condition of the roadway, and the strength of the rusted pallet decreases rapidly; (2) It is heavy, and it is difficult for underground workers to carry and construct, and the labor intensity is high; (3) It is not compatible with metal tools Collisions are likely to generate sparks and cause local gas explosion...
