Coal chemical gasification slag and coal gangue backfill material and preparation method thereof
The invention discloses a coal chemical gasification slag and coal gangue backfill material. The coal chemical gasification slag and coal gangue backfill material comprises the following raw materials: main raw materials: gasification slag, coal gangue, fly ash, furnace slag and sludge; the auxiliary materials comprise the following raw materials in parts by weight: 30-80 parts of gasified slag, 20-80 parts of coal gangue, and water, a reinforcing agent, a curing agent and cement. According to the coal chemical gasification slag and coal gangue backfill material and the preparation method thereof, the coal gangue and the gasification slag are adopted as main raw materials, the occupied specific gravity is large, the overall cost of the backfill material is reduced, and the overall density of the coal gangue and the gasification slag is small; auxiliary materials such as cement, fly ash and a curing agent are added into the backfill material to improve the overall structural strength of the backfill material, so that the backfill material has the advantages of high strength and low porosity; the preparation process is simple and easy to implement, the main raw materials are easy to obtain, and the backfill material is low in raw material cost, low in cost compared with a traditional backfill material and small in influence on the environment.
本发明公开了一种煤化工气化渣煤矸石回填料，该煤化工气化渣煤矸石回填料原料包括：主要原料：气化渣、煤矸石、粉煤灰、炉渣、污泥；辅料：水、增强剂、固化剂、水泥，其中各原料分量为：气化渣30～80份、煤矸石20～80份。该煤化工气化渣煤矸石回填料及制备方法，采用煤矸石和气化渣作为主要原料，占用较大比重，降低了回填料的整体成本，且煤矸石和气化渣的整体密度较小，并通过向内部添加水泥、粉煤灰、固化剂等辅助材料来提高该回填料的整体结构强度，使得该材质回填料强度高，且孔隙率低的优点；该制备工艺简单，容易实现，且主要原料容易获取，并且该回填料的原料成本较低，相较于传统的回填料成本低，且对环境的影响较小。
