Abstract: In order to reasonably solve the problem of large deformation of the mining roadway in the middle and lower layers of Laogongyingzi Coal Mine, this paper discusses the relationship between the overburden stratum movement and the stability of the surrounding rock based on the actual geological conditions of the 5# coal seam, and brings to light the erratic mechanism of the surrounding rock of roadway. It indicates that the additive effect of mining stress is the key factor causing the instability of the surrounding rock of the first mining face; It is becoming an asymmetric structure caused by the secondary rupture of the overlying rock forms , so notable partial loads is the prominent case affecting the unstable surrounding rock of the continuous working face ,and the narrow coal pillar is repeatedly disturbed by the mining, severe plastic destroy and reduced bearing capacity bring the unstable surrounding rock of the roadway. Based on the above analysis, the surrounding rock control idea of “enclosed and strengthened and differentiated treatment” is proposed,it has developed the self-supporting capacity of the surrounding rock by the surface shotcrete internal grouting , and it is the redouble anchor cable firming the brush-fire support power of the surrounding rock. It’s proved by the Field practice that the narrow coal pillar roadway can meet the requirements during the mining face ,the stability is better,and it is a reference for the improvement of the surrounding rock control of similar roadways.
