摘要/Abstract

摘要： 近年来，随着开采技术的发展，急倾斜薄矿脉采用中深孔采矿越来越多。为了降低生产成本，提高经济效益和安全系数。通过在矿房对扇形中深孔和平行中深孔进行现场试验，得到扇形中深孔比平行中深孔工程量少、千吨采切比小的结论。将扇形中深孔采矿方法在急倾斜薄矿脉中进行推广应用，取得了一定经济效益。

关键词: 急倾斜薄矿脉扇形孔平行孔

Abstract: In recent years,with the development of mining technology,medium and deep hole mining has been increasingly adopted in steeply inclined thin veins.In order to reduce production costs,improve economic efficiency and safety factor.By conducting field tests on fanshaped mediumdeep holes and parallel mediumdeep holes in the mining room,it is concluded that the fanshaped mediumdeep holes have less engineering volume than the parallel mediumdeep holes and a small cuttocut ratio of 1,000 tons.The fanshaped mediumdeep hole mining method has been popularized and applied in steeply inclined thin veins,and has achieved certain economic benefits.

Key words: steep,thin ore body,scallop hole,parallel hole
