Abstract: In order to quickly determine the type of support for 301 working face of Buertai Coal Mine, the movement law of
overlying strata in the working face was analyzed theoretically. Based on geological parameters and experimental test data, the
support strength, working resistance and initial setting force parameters of the support were analyzed, and the ZF 15000/27.5/42
four pillar shield support was selected. The actual support results showed that the support effectively reduced the deformation of
surrounding rock, the support parameters met the support design requirements, and the support selection was reasonable, which
can provide reference for similar research.

Key words: working face support; overlying strata; working resistance; support strength; initial setting force
