中空注浆锚杆特点

1、将锚杆和注浆管的功能合二为一、注浆时它是注浆管，注完浆后无需拨出即成为一根锚杆。
2、中空设计使锚杆实现了注浆管的功能，避免了传统施工工艺注浆管拨出时造成的砂浆流失。
3、注浆饱满，并可实现压力注浆，提高了工程质量。
4、杆体的居中性好，砂浆可以将锚杆体全长包裹，避免了锈蚀的危险，达到长期支护的目的。
5、安装方便，不需现场加工螺纹，就可方便的安设垫板、螺母。
6、结合配套的锚杆专用注浆泵和注浆工艺，是目前国内唯一彻底解决了传统锚固支护诸多问题的锚固体系。

π型梁支护优点

（1）支护整体性强。对于地质构造影响，造成的破碎顶板，支护效果明显好于铰接顶梁。
（2）开采进度适应范围广。开帮进度可大可小，尤其是当工作面开采过程中煤层顶板发生变化时，它均可以适应。最大进度达1m以上，大大提高煤层生产能力，提高循环产量，从而提高单产。
（3）三铁工作量减少。由于π型梁支护工艺与支护工艺是连续性的，工作面支柱很难丢失，而铰接顶梁支护时先由软帮放完顶以后，才去给硬帮给柱，单体柱从软帮跨过工作面溜子到硬帮时间较长，容易丢失。同时π型梁、单体柱在整个过程中始终处于工作状态，不存在倒地的过程，使三铁管理工作同时增加了主动性。π型梁与铰接顶梁相比，免去了水平销的使用，即减少了投入，又免去了丢失的可能。
