锚喷支护在我国煤炭系统的井巷支护中应用很多,在冶金、交通、水电、军工等地下工程也大量采用,其中有30米跨度的地下工程,有千米立井的井筒支护,有的工程已经过14年的考验。锚喷支护的理论探讨和科学实验的逐步深入,为这一新技术的应用打下了坚实的基础。与传统支护相比较其主要优点是:
Bolting and shotcrete support is widely used in mine roadway support in China’s coal system. Underground engineering such as metallurgy, transportation, hydropower and military are also widely used. Underground engineering with a span of 30 meters, wellbore support with 1000m vertical shaft, Some projects have passed the 14-year test. The theoretical discussion of anchor and shotcrete support and the gradual deepening of scientific experiments laid a solid foundation for the application of this new technology. Compared with the traditional support its main advantages are:
