The Rock Geomechanical Assessment And Bolting Support Technology Research Of Xqiao6Coal Mine

The roadway bolting technology change passive support to active support, give full play to the carrying capacity of the rock itself, and because of its easy construction, low labor intensity and save resources, and many other advantages, making coal mine preferred way to care for. Bolting technology in China rapid development and promotion efforts, to promote the reform of roadway support, and gradually become the mainstream of roadway support. With the constant innovation and experience in the construction site bolting technology design theory and support the continuous accumulation of roadway support sets of increasingly sophisticated technology, which is suitable for the formation of a series of rock classification coal roadway system and the corresponding technical specifications bolting technology from mere academic research into safe and efficient production of coal mining enterprises services.The summarizes the development process of bolting coal roadway, roadway damage and bolting mechanism is proposed to rock geomechanical assessment based bolting design ideas.611316coal mine in Xieqiao face, for example, from the aspects of physical and mechanical testing of coal and rock analysis, observing rock structure, stress measurement analysis of six coal rock geomechanical assessment, and on this basis to conduct roadway Stability classification. And Coal roadway bolting technical specifications (MT1104-2009) for the design principles for11,316initial face support parameters.11316working face in combining geological conditions and support parameters, based on the use of numerical simulation software supporting the initial calculation parameters and support parameters optimization.11316mining face in tunneling and mining during the arrangement of rock pressure observation stations on the roadway deformation and failure to conduct observation and analysis, from11,316roadway live rock pressure observation point of view, this face has been effectively coal roadway support. So far, the coal roadway bolting design programs have been validated in theory, experiment and field engineering practice, not only makes the coal face, Lane11316completed within the required service life of production safety, while other Xieqiao coal mine6Face roadway support design also provides a good reference.
