Application and Development of Resin Capsules in Chinese Coal Mines

Abstract

Development and application of resin capsules in Chinese coal mines were introduced in this paper, including the category, feature, applicability and basic parameters. The paper pointed out that unsaturated polyester resin capsules were the most widely used in Chinese coal mines. A kind of newly-developed low-viscosity resin capsule was applied to industrial test in Fengshuigou Colliery, and the results showed that the high pre-stress and intensive bolting system could effectively control the violent displacements of the surrounding rock, and it provided an effective approach for the support of soft rock roadway. Finally the future developments of resin capsules were prospected.

Study on Influence of Rock Strength on Anchorage Performance of Resin Anchored Bolts

“…Meshing was a key step in model. The model was established according to the actual sizes of the bolt, resin capsules and the surrounding rocks [10][11][12][13][14]. The 3d model shape sizes of 450mm*280mm*4mm (length*width*height) were adopted.…”
