生产矿山开采深度的加大和矿山地质条件复杂的新矿床的开发,都对地下矿山巷道的支护提高了要求。支架迅速地达到承载能力,对爆破动载荷的稳定性也具有越来越大的意义。因此,所采用的支护结构和材料的范围在不断扩大,并不断以更加完善的结构取代传统的支护形式。 The increasing exploitation of production mines and the development of new deposits with complex geological conditions in mines have raised requirements for the support of underground mine tunnels. The support quickly reaches the bearing capacity and has more and more significance to the stability of the dynamic load of blasting. As a result, the range of support structures and materials used is constantly expanding and the traditional form of support is constantly being replaced by more sophisticated structures.
