摘要： 为制备原煤的相似材料，选用煤粉和沙子为两种骨料，石膏和水泥为胶结剂，应用单因素分析法，分别就煤粉、石膏、水泥和沙子之间的不同配比对相似材料强度的影响进行了试验研究.结果表明，以煤粉为骨料的相似材料，其试样强度与煤粉用量呈线性负相关，且相关性显著，相似材料性能也易掌控;而以沙子为主料的相似材料，其试样强度与沙子用量呈非线性关系，试样强度波动较大，相似材料性能不易掌控.因此，以煤粉做原煤相似材料的骨料比沙子要合适，研究结果为原煤相似材料的制备提供了借鉴.

Abstract: Coal powder and sand are both used as two kinds of aggregates， and both gypsum and cement are used as cementing agent in the similar material preparation of raw coal. Through the single factor analysis， the influence on the strength of similar material under different composition proportions of coal powder， gypsum， cement and sand was studied during the experiments. The results indicated that the similar material of coal powder as aggregate shows a negative linear correlation between the strength and coal powder consumption dosage， meanwhile， the properties of similar material is easy to be controlled. While the similar material that uses sand as the aggregate shows a non-linear relationship， and the properties of similar material is difficult to be controlled. Therefore， the coal powder is more suitable than sand as the aggregate of similar material of raw coal.The results provide good references for similar material design of raw coal.
