Abstract: This paper puts forward the basic criterion and methods for bolting according to the geological condition and mechanical properties of rock surrounding coal roadway under various difficult and complex conditions. If necessary, the anchorage cable and grouting can be taken as auxiliary measure to reinforce the surrounding rocks. The obvious technical and economical effects have been obtained in two engineering projects.
