摘要:
缓倾斜薄矿体作为一种难采矿体，一直是国内外各矿山的研究重点。基于早子沟金矿缓倾斜薄矿体，开展了长壁式连续采矿法试验研究。该方法具有连续采矿、采矿回采率高、安全性好等优点，普遍应用于水平、近水平及缓倾斜矿体。通过与早子沟金矿原有房柱采矿法采矿工艺对比，长壁式连续采矿法在万吨采掘比、回采周期及采矿回采率等方面具有较大的优势，可作为一种高效的采矿工艺在非煤矿山领域进行推广应用。

Abstract:
As a hard-to-mine ore body,moderately thin ore bodies have always been a research focus in both domestic and international mines.Based on the moderately inclined thin ore body of Zaozigou Gold Mine,experimental research on the longwall continuous mining method was conducted.This method has advantages such as continuous mining,high mining recovery rate,and good safety,and is widely applied in horizontal,near-horizontal,and moderately inclined ore bodies.Compared with the original room-and-pillar mining method in Zaozigou Gold Mine,the longwall continuous mining method has significant advantages in terms of mining ratio (per 10 thousand tons),extraction cycle,and mining recovery rate,making it an efficient mining process that can be promoted and applied in the non-coal mining industry.
