摘要
针对松桃县西溪堡锰矿缓倾斜薄矿体的采矿方法开展探索实验及研究,结合西溪堡锰矿矿南矿区及北矿区矿体厚度、倾角及顶板稳定性多变的特点,采取调整控制切割巷道断面、采空区跨度及巷道布置形式,配置合适的采矿机具,提高了回采率,降低了贫化率,矿山取得了较好的经济效益。
We have carried out the exploring experiment and research of Xixibao manganese slowly-inclined thin orebody,in combining with the mining ore body thickness in the south and north.Dip Angle and the features of roof stability are raised to adjust the control cutting roadway cross section,including the gob span,roadway layout and configuration suitable mining machinery.It improves the recovery rate in reducing the dilution rate.The mine has achieved good economic benefit.
