Buried azimuth angle influence on the mechanical properties of the rock

摘要

Aiming at Panji third mine reverse faults F24 around the 1642 (1) transpotation roadway and the total return air shipment of west one coal group B, analysis F24 thrust attachment rocks buried azimuth effect on the rock mechanics properties;Through the core level positioning device and core drill, starting operation of core work around F24 thrust attachment in downhole, and fetching out core marked horizontal direction in advance from drilling core, marked out with the 3d coordinate state;Then using secondary core device fixed Angle and the rock drill in the laboratory, taking out the direction of six sample;Then using the RMT-150B rock mechanics test system, to conduct uniaxial compression test on different direction of rock specimen, listing analysing the obtained experimental results in the form of graphics and tables, finally using RFPA software,returning the evolution of rock triaxial confining pressure test.
