摘要
锚杆支护是煤矿开采的重点推广项目, 然而锚杆支护在回采巷道推广却比较缓慢,其主要原因就是锚杆的选型、设计( 工艺) 与使用条件不尽合理。今根据不同地质条件与岩性,提出锚杆支护在回采巷道中设计选型的基本原则, 供采矿工作者参考, 以利扩大推广锚杆的使用范围。
Bolt supporting is a key object to spread of coal mining.But it was somewhat slow in making way into wide use,the reasons are the mode selecting,the technical design and the unreasonable operating condition of bolt supporting.Now,based on different geological conditions and the natures of rock,the basic principle of design and selection of bolt supporting in actual mining roadway is offered.This paper would provide a reference to mining workers to extend the limits of its application helpfully.
