Coal aggregate high-calorific-value paste filling material for coal mine
The invention provides a coal aggregate high-calorific-value paste filling material for coal mines, which comprises the following components in percentage by weight: 66-75% of solid material and 25-34% of water, wherein the solid material comprises the following components in percentage by weight: 12-16% of fly ash, 14-28% of auxiliary material, 1-3% of cement and 57-64% of coal aggregate. The invention provides the high-calorific-value paste filling material taking coal as aggregate, the requirements of room-and-column filling and later arrangement of a long wall surface to implement fully mechanized mining on the mechanical properties of a filling body can be met, and a filling body can keep a higher calorific value and has small influence on the coal quality of coal mined together.
本发明提供了一种煤矿用煤骨料高热值膏体充填材料，包括如下按重量百分比的组分：固料66％～75％和水25％～34％，其中，所述固料包括如下按重量百分比的组分：粉煤灰12％～16％、辅料14％～28％、水泥1％～3％和煤骨料57％～64％。本发明提供了一种以煤为骨料的高热值膏体充填材料，可满足房柱式充填及之后布置长壁面实施综采对充填体力学性能的要求，且充填体可保持较高的热值，对一同采出的煤炭的煤质影响小。
