摘要
针对金厂峪金矿采空区附近的缓倾斜薄至中厚矿体的回采 ,开展了采矿方法与回采工艺过程研究 ,提出了逆倾斜和沿倾斜两次回采并配合加固措施的采矿方法 ,确定了合理的采矿结构参数。该方法在试验矿块取得了成功 ,并正在全矿推广 。
Research of the mining method and extraction process were made for the extraction of the gently inclined thin to medium thick ore bodies around the mined area of Jinchangyu Gold Mine.A mining method including both counter inclination extraction and along inclination extraction and reinforcement measures was suggested and rational mining structural parameters were determined .The method has achieved success in test blocks and is popularized in the whole mine,which has achieved good economic results.
