摘要： 为了提高巷道的支护强度和表面的光滑度，需要在巷道表面喷射混凝土，这种方式与锚杆支护合称为“锚喷
支护”。在喷射混凝土时所采用的喷射技术和设备对支护的效果十分关键。分析了煤矿锚喷支护中喷射混凝土技术和相应
设备的发展，并对其未来的发展趋势进行了展望，可以为锚喷支护技术的改进提供一定的参考。

Abstract: In order to improve the support strength and surface smoothness of the roadway, it is necessary to spray concrete on
the roadway surface, which is called "bolt shotcreting" together with bolt support. The shotcreting technology and equipment used
in shotcreting are very important to the effect of support. This paper analyzed the development of shotcreting technology and
corresponding equipment in bolting and shotcreting support of coal mines, and looked forward to its future development trend,
which can provide some reference for the improvement of bolting and shotcreting support technology.

Key words: bolting and shotcreting support; shotcreting technology; equipment; development trend
