Preparation material of remolded coal series mudstone sample and batch preparation method thereof
The invention belongs to the field of rock mechanics experiments, and relates to a preparation material of a remolded coal series mudstone sample. The material comprises the following components, by mass: 5-15% of pulverized coal, 10-20% of bentonite, 5-10% of clay, 30%-40% of quartz sand, 5%-15% of the cement, and the balance being water. In a laboratory, the characteristics of calcium bentoniteor sodium bentonite are utilized to simulate the water absorption characteristic and expansion deformation characteristic of mudstone, the characteristics of quartz sand and cement are utilized to simulate the sandy components and strength of mudstone, and a certain amount of on-site coal sample, clay and purified water are added. A remodeling experiment rock sample is obtained by using a specialplastic drying grinding tool according to different proportions to carry out a rock mechanics experiment, and a proportion closest to the mechanical property of an on-site rock sample is selected to prepare carbonaceous mudstone samples in batches to carry out mechanical evaluation.
本发明属于岩石力学实验领域，涉及一种重塑煤系泥岩样的制备材料，包括以下组分：煤粉、膨润土、粘土、石英砂、水泥和水，其中各组分的质量占比为：煤粉占总料比重为5％～15％，膨润土占总料比重为10％～20％，粘土占总料比重为5％～10％，石英砂占总料比重为30％～40％，水泥占总料比重为5％～15％，其余占比为水，在实验室利用钙基膨润土或者钠基膨润土的特性模拟泥岩的吸水特性和膨胀变形特性、利用石英砂和水泥的特性模拟泥岩的砂质成分和强度、再加上一定量的现场煤样、粘土和纯净水，利用专用塑性烘干磨具按照不同配比得到重塑实验岩样进行岩石力学实验，并选取与现场岩样力学性能最接近的配比批量制备炭质泥岩样品进行力学评价。
