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。 In view of the high output rate of mining block, the top plate is not flat and there is such a problem in the accident of falling from the mine, the paper points out that the key to the mining management of the stope lies in optimizing the blasting parameters and detonating network. Practice has proved that under the strict construction quality assurance, the application of joint detonation technology, fundamentally solve the unsafe stope roof, large output rate of the problem, and achieved good economic results.
