本文针对小官庄铁矿矿体赋存的具体特点,在首层开采中成功地采用了低采准比、高开采强度的深孔、中深孔并段回采技术。并在实际生产中解决了凿岩、装药设备以及高切割等技术难题,推进了无底柱分段崩落采矿方法结构和工艺的变革。对其它类似矿山具有一定的参考价值。
In this paper, according to the specific characteristics of the ore deposit in Xiaoguzhuang Iron Mine, the deep and middle deep-hole section recovery technology with low mining-to-mining ratio and high mining strength has been successfully adopted in the first floor mining. In the actual production, it solved the technical problems of rock drilling, charging equipment and high cutting, and promoted the change of the structure and technology of subsea caving mining. For other similar mine has a certain reference value.
