摘要
卅亩地选矿厂１＃球磨机传动基础产生了裂缝，拆除爆破中通过试爆调整炸药量与布孔参数，使用药与布孔问题趋于合理，并采取一定的技术措施解决了裂缝爆破漏气问题，同时还对特殊情况下的震害传播问题作了探讨。
The base of transmission of 1~# ball mill at Sanshimudi concentrator come into beingcranny. In the demolition blasting the detonator quantity and disposing orifice parameter was adjusted by blasting test, which made detonator consumption and dispose orifice reasonable, and gasleakage was avoided by taking some technical measures. At the same time, shaking endangermentspread under special condition was discussed.
