实验室开展“固-气”耦合相似模拟实验，是研究卸压瓦斯运移规律的主要方法之一，煤岩瓦斯“固-气”耦合相似模拟材料的开发是“固-气”耦合相似模拟实验的基础。借助正交实验方法，将已选胶结材料石蜡和油作为影响相似材料的主要因素，对试件在改变胶结剂材料含量的条件下开展正交实验，分析石蜡和油对试件弹性模量E及渗流速度v的影响。从抗压强度σc、抗拉强度σt、弹性模量E、脆性参数E/λ及渗透性等方面，对不同配比条件下的相似材料试件开展实验研究。通过对实验数据的拟合，并结合渗透率计算公式，得到了渗透率随石蜡含量变化的方程，表明相似材料渗透率随着石蜡含量的增加，呈负指数函数变化。从而研制出能够应用于“固-气”耦合物理相似模拟实验的相似材料，为“固-气”耦合物理相似模拟实验的开展奠定了基础。

Solid-gas coupling simulation experiment in the lab is one of methods of studying on the law of relief methane migration. Development of similar material of coal-rock and gas solid-gas cou-pling is the basis of the simulation experiment. The cementing material of paraffin and oil have been chosen as affecting factors to carry out the orthogonal test under the condition of changing the content of cementing agents. The influence of paraffin and oil on elastic modulus E and flow rate v of the simi-lar material test-pieces is analyzed. Different proportions of similar material test-pieces have been re-searched in compressive strength σc, tensile strength σt, elastic modulus E, brittle parameter E/λ and permeability. The equation of permeability has been obtained by combining permeability calculation formula and negative exponential fitting formula of experimental data. It is shown that with increase of paraffin content the permeability present negative exponential. The similar materials can be used in physically simulating experiment, which lays a foundation for the solid-gas coupling physically simu-lating experiment.
