针对九杖沟金矿矿床赋存于区域构造带内，矿体走向上表现为中间矿体宽厚，向两端逐渐变窄的透镜状呈脉状产出，沿倾向呈舒缓波状，矿岩稳固性差。依据矿体的赋存条件及开采技术条件，对中厚矿体缓倾斜矿体采用分段充填法进行开采，分段采准，连续回采工艺；分段凿岩，采用上向中深孔落矿，铲运机出矿，嗣后充填，通过现场进行工业试验该方法取得了较好的技术经济效果，为类似矿床开采提供依据。

The ore deposit of Jiuzhanggou Gold Mine occurs in the regional tectonic zone . The ore bodies oc-cur as veins showing a narrowing from the middle to two ends in thickness along the strike and present slightly wavelike shape along the dip . According to the conditions of ore bodies and mining technology , sublevel filling method is adopted in the mining of medium -thick and gently inclined ore bodies . T he min-ing operation includes the sublevel preparatory work and continuous mining , the upward and medium -deep hole blasting , the loading -hauling ore by scrapers and subsequent filling . By the field industrial test , this mining method has achieved good technical and economical results , providing a basis for the simi-lar mines .
