导爆索、导爆管联合起爆技术在采场落矿工艺中的应用

The application of combined detonation technique of detonating fuse and tube in the technology of ore dropping out

针对采场落矿大块产出率高，顶板不平整，冒落事故时有发生这一难题，文中指出了采场落矿管理的关键在于优化爆破参数及起爆网络。经实践证明，在严格的施工质量保证下，应用联合起爆技术，从根本上解决了采场顶板不安全，大块产出率高的问题，取得了较好的经济效果。

Countering the great productivity of chunk of dropping out ores and frequently arised accident of fall in the blasting operation of stopes,the optimization of blasting parameters and detonating network must be made ,so the combined detonation technique of detonating fuse and tube must be taken.Practice showed that the application of the said technique caused the difficult problems of “insecure roof” and “overproduced chunk of dropping out ores”solved in the guarantee of fine construction quality.In this way,a better economic effect was achieved.
