Abstract: Similar materials for coal and gas outburst are the foundation to carry out the simulation experiment of coal and gas outburst. With the research on the similar materials of outburst coal, the outburst phenomenon can be precisely represented in the tests. This paper concludes the research status of the similar materials of outburst coal. The factors that may affect the mechanics, adsorption and desorption and permeability performance of the materials during the manufacturing process are collated and listed, and further research develop directions on the similar materials of outburst coal are listed: measuring the performance of materials on the mechanics, adsorption and desorption and permeability; standardizing the raw materials and manufacture technology; detailing the method of quantitative evaluation for the materials.
