锚杆支架是澳大利亚煤矿巷道中普遍采用的支护形式,90％以上的开拓巷道和采准巷道都采用锚杆支护。在采准巷道中无论是房柱式采煤法,还是长壁采煤法都采用锚杆支护。实际上为了报废工作面,所有的工作面小顺槽和巷道都用锚杆支护。锚杆支架也是一切类型的巷道(包括通往地面的原煤主运输道皮带上山的开拓巷道)的主要支护。应当强调指出,澳大利亚煤矿井下的顶板条件是很复杂的。有些顶板的地质力学参数很好,也有很难维护的和薄层破碎顶板岩层。 Anchor support is commonly used in Australia coal mine tunnel support form, more than 90% of the development of the roadway and the roadway are adopted bolt support. In the quasi-entry lane, whether it is the house-column mining method, or long-wall mining method are used bolt support. In fact, in order to scrap the work surface, all the facets and tunnels are all supported by bolts. Anchor brackets are also the main support for all types of roadways, including the open pit laneways leading up to the belt of raw coal to the ground. It should be emphasized that roof conditions in coal mines in Australia are complex. Some roofs have very good geomechanical parameters and also have hard-to-maintain and thin-crushed roof strata.
