Abstract: The ground pressure performed significantly as its conditions in island coal face， the phenomenon of coal wall spalling often be encountered in mining，and threats to use the roadway and face safety production，in order to solve this problems，this paper used micro-fine cement to control the coal wall spalling.Studied the relationship between fine cement viscosity and coagulation of the mixed slurry，and obtained the flow ability and coagulation is enhanced with the increase of water- cement ratio；Added some soundless cracking agent into grouting material，and the expansion of grouting material turned the original 1.09 into 1.18；From laboratory compression tests of K8113 coal，we know the compressive strength of coal is 2.234 MPa；The lump of coal samples with fine cement composition according to mass ratio of 7∶3，after 72 h its compressive strength increases to 7.864 MPa.According to the practical application of the K8113，the results showed that： micro-fine cement to control the coal wall spalling in island face is feasible.
