Abstract No.1 deposit body is the main deposit body of Jinchuan mine. It is also the body of the second exploitation period in the second mining zone. Because of deep embedding，great geopressure，high in-situ stress，many joints in rock and poor stability of wall rock，the geopressure control and maintenance of laneway stability become a key technological issue during the exploitation. In selecting the best control measure of stope and the timbering technology of laneway，the system analysis and parameter optimization，geological engineering research and rock quality evaluation are the basis of underground work. Thorough research and an on-the-spot investigation are carried out in Jinchuan deposit. On this basis，the engineering wall rocks are classified and the quality of the rocks are evaluated.

Key words： geology rock quality exploitation of deposit body stability
