摘要
新城金矿为蚀变岩型金矿床,由于受地质构造影响,顶板稳定性较差,局部和较大面积的顶板冒落现象时有发生,为了解决采场顶板安全问题和提高落矿主要技术经济指标而进行了“上向水平分层尾砂胶结充填法采场控制爆破技术”的试验研究工作,试验达到了预期效果。
Xincheng Gold Mine is an altered type gold deposit. Influenced by geological structure, the stability of stope roof was poor and roof collapse often took place locally or in a greet area. For the satety of stope roof and raising technical economic index, a controlling blasting technique for ore caving of the stope was tested in order to conduct upward horizontal slicing and filling with cemented tailing. A desired result was obtained in the test.
