摘　　要：针对弓长岭井下矿现有支护方式与岩体变形不相适应的问题,分析了各种支护形式的优劣,通过调查被破坏巷道的尺寸,得出了不同岩性的沿脉和穿脉巷道的自稳跨度,确定了合理的巷道断面尺寸,根据巷道破坏后的自稳形状,改进了巷道断面形状,并提出了喷锚网支护方式,变被动支护为主动支护,预计能够较好地解决原有支护形式存在的问题,确保矿山的安全生产。The merits of different support forms are analyzed to address unsuitability of the existing support method for deforma- tion of the rock mass in Gongchangling Underground Mine. The self-stability spans of strike drift and transverse drift in different lithology are obtained by surveying the size of failed roadway to determine the rational section size roadway. The cross-section shape of roadway is improved on the basis of the self-stabilized shapes of roadway in failure. The spray anohor supporting system is proposed to introduce the active support system instead of the passive support system, which expects to be able to solve the problem of inadequacy of the existing support form, ensuring safety in production for the mine.
