摘要
针对袁家村铁矿采空区分布范围广、数量多、空腔形态复杂的特点,通过物探与钻探方式的研究,优化出最佳的钻探网度;采用三维空腔扫描的手段,准确掌握空腔形态;采用综合技术,研究出了顶板最小安全厚度;通过优化爆破参数和起爆网络,采用崩落法有效处理了大型采空区,为采矿安全生产创造了条件。
According to the characteristics of wide distribution, large quantity, complex cavity shape in Yuanjiacun iron mine goaf,through the study of geophysical and drilling mode, the mine optimizes the optimal drilling network and adopts three dimensional cavity scanning method to accurately grasp the cavity shape. The article adopts the comprehensive technology to research the minimum safety thickness of roof. Through optimizing blasting parameters and blasting network, the mine adopts caving method to effectively deal with large goaf, which creates the conditions for mining safe production.
