摘要
北京首云铁矿薄矿体以前主要采用浅孔留矿法开采,由于该采矿方法在回采过程中安全隐患较大、回采效率较低,已经不能满足矿山生产、安全要求。因此,矿山改变采矿方法,采用中深孔分段空场法进行回采。通过优化采切设计参数,提高了生产效率、降低了生产成本。同时总结了生产过程中存在的问题,可为其它矿山回采类似矿体提供参考。
The shallow hole shrinkage stoping method used for thin ore body iu Beijingshouyun Iron Mine can not meet the production and safety requirements because of the hidden danger and lower extraction efficiency. Therefore, the medium-length hole sublevel stoping method was adopted. Through the optimization of mining and cutting parameters, the production efficiency increased and the production cost reduced. The problems existing in production was summarized, which can provide reference for other similar ore mining.
