| Abstract: | Based on bolt and cable support parameters design about close coal seam in the Ganzhuang coal mine, starting from the aetual distance seam roadway for the mine roadway support the status quo, by MIDAS / GTS numerical sinmlation, analysis distance seam roadway fordisplacement, stress and the extent of damage distribution, supporting the body force status; different factors impact on the surrounding rock deformation and failure of different support parameters supporting effect; through the program, determine reasonable support parameters. Designed to improve the bolt and cable support parameters scientific rationality and practical reliability, and further play to the potential of bolting technology the, close coal seam support care to provide a theoretical basis and technical support. |
