The invention discloses a similar material for coal and gas outburst simulation experiments and a preparation method thereof. Pulverized coal is used as aggregate, cement is used as adhesive, sand, water and activated carbon are used as auxiliaries, a mixture of two pulverized coal with different granularities is selected, and the requirement for simulating raw coal in mechanical experiments can be met. The material can take mechanical property and adsorption performance of an outburst material in consideration and has a high similarity level in the physical mechanical property, the similarity of physical mechanical property and gas adsorption performance between the similar material and III-V type destroyed coal can be guaranteed by regulating the proportion of auxiliaries. The material is simple in manufacture process, can be used for manufacturing a large-sized outburst similar material, and can meet the consistency between coal and gas outburst experiment phenomenon and actual coal and gas outburst.
