合成应力爆破模型在长时间内具有具体描述爆破过程的潜力、但目前只应用在研究中
In the long term, a hybrid stress blasting model has the potential to provide a practical description of the blasting process but is currently limited to research applications
因为缺乏成熟的机械破碎模型、爆破行业只好依赖经验方法
The blasting industry has had to rely on empirical approaches in the absence of a proven mechanistic fragmentation model
气体的形成在很大程度上取决于诸多因素、如现场实际爆轰条件、岩石类型、炮孔直径、有没有水以及炸药在炮孔中是否均匀等
The gas composition is strongly dependent on many factors such as actual field detonation conditions, rock type,hole diameter,water presence,product homogeneity in the hole
由于岩石破碎不理想、影响到开采计划的实施、进而影响到开采成本、常用的爆破破碎模型只能对破碎曲线进行粗略分析
Current blast fragmentation models tend to focus on the coarse end of the fragmentation curve because of the impact of poor fragmentation on excavation performance, and hence excavation costs
