文中论述了从实测巷道围岩变形出发,分析了采动巷道破坏的原因,得到了围岩变形与时间因素的关系。试验推广了简易光面爆破和各种岩性巷道的喷锚支护方法。同时还实践了缩短凿岩机气腿行程,采用双环锚杆等技术措施,提高了喷锚支护的工程质量。 Starting from the deformation of the measured roadway surrounding rock, the reason of the roadway destruction is analyzed, and the relationship between the deformation of the surrounding rock and the time factor is obtained. The experiment popularized the simple smooth blasting and the shotcrete and bolt supporting methods for various lithology roadways. At the same time, it also practiced to shorten the leg stroke of rock drill and adopt double-ring anchor bolt and other technical measures to improve the engineering quality of shotcrete and bolt support.
