摘要
巷道的变形破坏是多种因素综合作用的结果。影响巷道稳定的原因主要包括构造应力、岩性、支护形式及参数等。合理确定注浆锚杆及支护参数,有效地控制了围岩变形,保证了巷道断面满足生产需要。
The deformation of roadway is the result of various factors.The reasons for affecting the stability of the roadway include tectonic stress,lithology,support forms and parameters and so on.Rationally determine the grouting bolt and support parameters,effectively control deformation of the surrounding rock,and therefore ensure the safety of the roadway section to meet the needs of production.
