In order to meet the need of long-term stable use of the 9-2001 roadway of Mugua Coal Mine,advanced geophysical prospecting and drilling technology was used to explore the geological structure characteristics of tunneling 9-2001 roadway,and the support scheme was designed through support theory analysis and theoretical calculation.The design adopted the combined support scheme of reinforced ladder beam + anchor cable + steel mesh.The support scheme can meet the long-term stable use needs of 9-2001 roadway,and provide a reliable guarantee for the remining of the 9-200 working face.
