水力充填指的是利用水力通过管道把充填材料送入采空区的充填方法。我国常用的水力充填采煤法主要倾斜分层走向长壁上行充填采煤法及倾斜分层倾斜长壁上行充填V型工作在采煤法。水力充填已成为深部矿山安全高效采矿整体中的一部分,水力输送系统已经从以故障频繁的“自由下落”系统发展到可靠的满管流系统。

介绍了水力旋流器在尾矿充填、分级、预浓缩工艺中的生产应用。
The paper introduces the application of hydraulic cyclones in tailing filling, grading, and prethickening.
在水力压裂期间输送支撑剂的流体，通常为油、水、泡沫或稠化液。在砾石充填期间输送砾石的流体也称为携带液。
The fluid, usually oil, water, foam, or gelled fluid that transports the proppants during hydraulic fracturing. The fluid that transports gravel during gravel packing is also called carrying fluid.
但它们在高温条件下容易导致粘度降低且在裂缝中漏失量很大，上述缺点限制了其在水力压裂和压裂充填措施中的应用。
But they may easily produce low viscosities and high fluid leak off from the fracture at high temperature, which limit their applications to hydraulic fracturing and fracture-packing treatments.
