矿山爆破开采对周围建筑物的影响

Effect of Mine Blasting on Nearby Buildings

通过对矿山爆破开采时爆破震动监测数据的分析和研究 ,总结出爆破震动对周围建筑物产生危害的主要影响因素 ,并根据现场测定数据 ,拟合出地震速度、药量大小与爆源距离之间关系式。现场测定结果与研究表明 ,必须重视爆破开采的地震规律及其对各种建筑物和构筑物影响的研究 。

Through analysis and study of the monitoring data of blast-induced vibration in mine blasting for mining, the main influential factors for the blast vibration-caused damage to nearby buildings are summarized. Based on the on-site measured data, the relationship among the seismic velocity the explosive amount and the distance to the blasting source is drawn. The on-site measurement results and study show that only by paying great attention to the study on the seismic law of blasting in mining and on its effect on various buildings and structures can the economic benefit of blasting technology be fully exploited and the danger caused by blasting vibration be brought to a minimum.
