| 摘 要： | 利用断裂与损伤力学理论，讨论了炮孔围岩中的应力场、损伤场和主裂纹开裂长度与炮孔内爆生气体膨胀压力的关系，从而可根据对围岩稳定性的要求和尽可能增大炮孔间距，提高施工速度，降低生产成本的原则来设计、优化爆破参数、装药结构和选择合适的炸药，指导生产实践。

| Abstract: | In this paper, the relation between stress and damnification field crazed length of main crack in wall rocks of boreholes and expanding pressure of gas produced by explosion in boreholes is discussed, based on the theories of rupture and dammification mechanics. Accordingly, in line with the request to stability of wall rocks and the principle to accrete the space between boreholes as much as possible, advance construction speed, and reduce production cost, production practices are directed by designing, optimizing blasting parameters, charging structure and choosing proper explosives. |
