Method for regulating and controlling porosity of coal body similar material and preparation method of coal body similar material
The invention provides a coal body similar material porosity regulation and preparation method, the coal body similar material comprises the following raw materials: pulverized coal, cement, gypsum, water and volatile solid particles, the prepared pulverized coal is used as an aggregate, the prepared volatile solid particles are used as a pore regulation material, and the cement and the gypsum are used as cementing materials; the strength of the similar material is controlled by adjusting the ratio of the aggregate to the cementing material, and the porosity of the similar material is controlled by adjusting the weight ratio of the volatile solid particles. The aggregate, the cementing material, water and the pore regulation and control material are mixed, stirred, pressed, formed, dried and maintained according to requirements, a test piece is prepared, the porosity is measured, and the weight ratio of the pore regulation and control material of the target similar material is calculated based on the weight ratio of different pore regulation and control materials of the test piece and a fitting formula of the porosity of the test piece. The strength property and the pore property of coal can be considered, the similar degree with the characteristics of raw coal is high, the used materials are wide in source, low in price and free of toxicity and harm, and the good application prospect is achieved.
本发明提供了一种煤体相似材料孔隙率调控及制备方法，煤体相似材料的原料包括煤粉、水泥、石膏、水和可挥融固粒，以配制煤粉为骨料，以配制可挥融固粒为孔隙调控材料，以水泥和石膏为胶结材料，通过调整骨料和胶结料配比来控制相似材料的强度，通过调整可挥融固粒的重量比来控制相似材料的孔隙率。将骨料、胶结料、水与孔隙调控材料按要求掺混搅拌、压制成型和干燥养护，制备成试件并测定孔隙率，基于试件不同孔隙调控材料重量比及其孔隙率的拟合公式，推算目标相似材料孔隙调控材料的重量比。本发明可兼顾煤的强度性质和孔隙性质，与原煤特性相似程度高，且所用材料来源广，价格低，无毒害，有较好的应用前景。
