前言我国目前在光面爆破作业中,多采用中威力的不偶合装药。作者通过爆破模型的试验,测出了应力应变随不偶合系数和比例距离增大而衰减的规律,分析了相邻炮孔间裂缝的形成、扩展和起爆时差的影响,以便在模型试验的基础上,弄清光爆机理、寻求合理的光爆参数,提供有效依据。但是,由于 Preface China’s current smooth blasting operations, the use of more power in the non-coupled charge. Through the test of the blasting model, the authors measured the law of stress-strain decay with the increase of the non-coupling coefficient and the proportional distance, and analyzed the influence of the formation, expansion and initiation time difference between the adjacent shots in order to test the basis of the model test On the clear light explosion mechanism, to seek a reasonable light burst parameters, to provide an effective basis. But due to
