摘要
从理论上入手分析了无底柱分段崩落法结构参数的演变过程 ,分析了大间距结构下爆破堆积和矿石脊部残留结合体与放出体的吻合关系 ,论证了大间距结构参数的合理性 ,并通过实验和实践进行了验证。也验证了这种能够大量减少采准工程量、降低采矿成本。
The evolutive process of the structural parameters of pillarless sublevel caving and the correspondence relationship between the combined object of explosion accumulation and ridge hangover under large space structure and the ejective object are analyzed theoretically. The rationality of large space structural parameters are expounded and proved in experiments and practice. It is also demonstrated that pillarless sublevel caving with large space structaral parameters which can substantially reduce the development work amount and mining cost and raise the equipment availability and mining strength will be the development orientation of pillarless sublevel caving.
