摘要
天井掘进是矿山开拓和采切工程最重要、最困难一环,因此利用既能提高作业安全性和效率又能降低施工成本的施工技术是最佳选择.文章以凡口铅锌矿天井掘进为例,详细阐述台车爆破一次成井技术在天井掘进的应用,给出了孔网参数、装药参数以及炮孔施工的工艺,取得了较好的爆破效果,可供类似工程参考.
Raise driving is the most important and difficult link in mine development and cutting engineering. Therefore,using the construction technology that can improve the safety and efficiency of operation and reduce the construction cost isthe best choice. In this paper, the technology of one time trolley raise blasting is described based on the application of raisedriving in Fankou Lead - zinc Mine as an example. The parameters of hole pattern and charge parameters are given. Andthe process of blasthole construction is introduced. The test achieved good blasting effect. It can be a reference for similarprojects.
