    摘要:

    某緩傾斜多層貧礦脈,礦區同時(shí)賦存鉛鋅、磁鐵和硫銅礦種,根據礦體的賦存特征及品位低等特點(diǎn),為了更加安全經(jīng)濟合理的開(kāi)采,提出了偽傾斜條帶進(jìn)路充填采礦法開(kāi)采方案,并利用FLAC3D軟件模擬分析了不同進(jìn)路寬度的頂板位移、礦柱受力情況和塑性區分布情況。研究表明魄缚,偽傾斜條帶進(jìn)路充填采礦法可有效減小礦石的損失貧化,極大的減小采切工程,增大采場(chǎng)的生產(chǎn)能力,并實(shí)現不同礦種的分采分運,可靈活適用于礦體復雜多變的緩傾斜礦體左炭,經(jīng)過(guò)數值模擬分析得到該礦山最佳的進(jìn)路寬度是5 m~6 m蔼于。

    Abstract:

    A certain gently inclined multi-layer poor ore vein is located in the mining area, which simultaneously contains lead zinc, magnet, and sulfur copper minerals. Based on the characteristics of the ore body and its low grade, a pseudo inclined strip entry filling mining method is proposed for safer and more economical mining. FLAC3D software is used to simulate and analyze the roof displacement, pillar stress, and plastic zone distribution of different entry widths. Research shows that the pseudo inclined strip entry filling mining method can effectively reduce the loss and impoverishment of ore, greatly reduce mining and cutting engineering, increase the production capacity of the mining area, and achieve separate mining and transportation of different types of minerals. It can be flexibly applied to complex and variable gently inclined ore bodies. After numerical simulation analysis, the optimal entry width for this mine is 5 m-6 m.
