锚索支护在煤矿开采中的应用

Application of Anchor Cable Support in Coal Mine Mining

介绍了锚索支护的发展过程及现状,从自承拱、组合梁和悬吊三方面分析了锚索支护技术的原理,并对锚索支护技术在煤矿巷道中应用时的参数计算和安装工艺流程进行了详细的论述。分析认为,锚索支护易于和锚杆、金属网等支护方式相配合,这对于降低支护成本、增加效益、提高支护可靠性具有重要意义。

This paper introduces the development process and present situation of anchor cable support, and analyzes the principle of anchor cable support technology from three aspects： self-supporting arch, composite beam and suspension. The parameter calculation and installation process of bolting support technology in coal mine roadway are discussed in detail. It is considered that bolting is easy to cooperate with bolting, metal mesh and so on, which is of great significance to reduce the support cost, increase the benefit and improve the reliability of the support.
