Abstract: With the working face through empty roadways as research background, combining with the actual situation of 5-103
working face through empty roadways of Jinbei Coal Industry Co., Ltd., this paper carried out numerical simulation. The numerical
simulation results show that 4 MPa is the turning point of filling strength. Therefore, through the comprehensive comparison of
different filling materials, the high water material was used for grouting construction. After filling grouting, the stability of roadway
surrounding rock was improved, the working environment was improved, which has provided the safeguard for the safe production.

Key words: working face through empty roadways; numerical simulation; filling grouting; supporting parameters
