近年来,随着我国煤巷锚杆支护的推广普及,在一些特殊的生产地质条件下使用锚杆支护有一定困难,不足以维护工程的稳定。为扩大锚杆支护使用范围,充分发挥锚杆支护的经济、快速、安全可靠的优点,在大断面、地质构造破坏地段、顶板软弱且较厚、高地应力、综放巷道等困难、复杂的巷道中,需要采用与锚杆支护相配套的支护形式和相关的技术。 In recent years, with the popularization of bolt support in coal roadway in our country, it is difficult to use bolt support under some special production geological conditions, which is not enough to maintain the stability of the project. In order to expand the use range of bolt support, give full play to the advantages of economy, speed, safety and reliability of bolt support. In the areas with large section and geological structure destruction, the roof is weak and thick, the high ground stress, Of the roadway, you need to use and bolt supporting supporting forms and related technologies.
