摘要
针对f>8硬岩工程地质条件,提出了基于炮掘法的设备选型和配置的经验理论。该理论建立了循环进尺与岩性、炮眼深度之间的数学模型,构建了破、装、运等设备的选型和配置方面的数学模型。鲁班山北矿运输大巷的生产实践表明,该理论创造了硬岩巷道最高月进尺433 m、平均月进尺400 m、平均工效4.17 m/(月·人)的技术水平。
According to engineering geological conditions of hard rock f〉8, experience theories of equipment selection and configuration are proposed based on blasting method. Mathematical models among cyclic-footage, rock types and borehole depth, mathematical models about selection and configuration of equipment for breaking, loading, transportation processes, are established in the theories. The practice in ＋475 in level main transportation roadway of Lubanshanbei mine shows that the theories created the new levels which have the highest monthly footage 433 m, average monthly footage 400m, and an average efficiency 4.17 m/（month.person）.
