The strong-weak coupling outburst prevention technology is an effective method to prevent coal and gas outburst by using hydraulic punching to weaken energy absorption and grouting to strengthen resistance. In order to study the mechanical characteristics of strong-weak coupling structures with different strength combinations, MTS uniaxial mechanical loading experiments were carried out on 9 coal-rock combination samples with different strength combinations, and the loading process was monitored using acoustic emission monitoring system. The results show that the increase of rock mass strength can effectively enhance the overall bearing capacity of coal rock combination, and enhance the ability of strengthening area to resist residual energy; The increase of coal strength can effectively reduce the overall deformation of the sample, shorten the duration of the compaction stage, and reduce the degree of partial coal fragmentation. The research results are of great significance to the optimization design scheme of strong-weak coupling anti outburst technology.
