摘　　要：介绍了在大裂缝多裂隙不良地质条件下,采用"封口、填缝、堵洞、隔断"等技术措施,通过缓坡主抛一侧的抛掷爆破,陡坡控制坍塌量一侧的松动爆破,靠近村庄一侧的辅助药包弱松动爆破和联合复式起爆网路的爆破技术,解决了大裂缝、多裂缝不良地质对爆破安全和爆破效果的影响,可为同类地质条件工程提供参考。The technical measures ＂sealing, filling, plugging the hole, partition＂ were used in the adverse geological conditions with large cracks and multiple fractures. The throwing blasting of main cast on one side of gentle slope, the loose blasting of controlling the slump quantity on one side of the steep slope, the auxiliary charge weak loose blasting near the village and combined with the blasting technique of joint compound priming circuit were adopted to solve the adverse effects to blasting safety and blasting effect caused by large cracks and multiple fractures. It could provide a reference for projects under similar geological conditions.
