| 摘 要： | 针对影响膏体充填材料强度的因素。通过大量的试验，揭示了以河砂为骨料的膏体充填材料强度与各影响因素间的关系。试验结果表明，影响膏体充填材料强度的主要因素有质量分数、粉煤灰掺量种类以及养护龄期等。相同条件下，膏体充填材料强度与料浆质量分数、粉煤灰掺量和养护龄期成正比关系。这些结论将为煤矿膏体充填不迁村采煤技术的实施提供一些参考。

| Abstract: | Aiming at the factors affecting the strength of paste filling material,the relation between affecting factors and strength of paste filling material is revealed on the basis of a lot of experiments in the lab,in which the river sand was used as skeletal material.The tests show that the strength is mainly affected by the slurry density,type and dosage of fly ash and curing age.There are direct proportion relation between the strength and affecting factors.The conclusions can provide some references for the practice of none-village-relocation coal extraction in the mine. |
