摘要
针对地下开采侧向挤压崩矿中存在待爆炮孔的保护和爆破破坏范围的控制等特定问题,对其影响因素进行了探讨,提出了控制爆破破坏范围的具体技术措施,并进行了一系列试验研究。试验结果表明,爆破破坏范围试验圈定值与定量预测计算值基本一致。
Protection of holes to be blasted and control of blasting damage zone, are the two issues to be addressed in underground lateral tight blasting. Factors affecting these two issues were discussed.Specific technical measures for control of the blasting damage zone were proposed and a series of experiments were completed. The results have shown that the size of blasting damage zone determined through the experiment was basically consistent with that of predited evaluation.
