Study on the Analysis of Secondary Anchoring Mechanism and Effective Distance

Abstract:

The paper is intent to open out the mechanism and effective distance of secondary anchoring in coal mine rock laneway support. Though the analysis of elastoplastic deformation, caused by heading face support removing in laneway development, the paper explained that secondary anchoring is necessary and important to rock laneway, and relatively exact data were given by FEM analysis. The paper illustrated a special example, and put it up with meticulous analysis, the results were not only having important reference value to coal mine soft rock laneway support, but also having definite use for reference to other mine soft rock laneway support.
