以沂南金矿金场矿区101号缓倾斜薄及中厚矿体为工程背景，开展了分步放顶阶段长壁控爆连续采矿新方法的试验及应用。采用连续开采方式，并相应的对采空区采用分步放顶卸压。详细论述了该方案特征及采准、切割、回采工艺。该采矿技术工业试验效果良好，对类似矿山的安全高效开采具有一定的借鉴与指导意义。
以沂南金礦金場礦區101號緩傾斜薄及中厚礦體為工程揹景，開展瞭分步放頂階段長壁控爆連續採礦新方法的試驗及應用。採用連續開採方式，併相應的對採空區採用分步放頂卸壓。詳細論述瞭該方案特徵及採準、切割、迴採工藝。該採礦技術工業試驗效果良好，對類似礦山的安全高效開採具有一定的藉鑒與指導意義。

Based on the inclined thin and thickness orebody at the 101 stope at Yinan Gold Mine , the sub -step caving and long -wall controlling blasting mining method was tested and applied . By applying the sub-step caving and continuous mining method , the underground pressure of stope was transferred to goaf . In this paper , the characteristic of mining method was introduced to mining development , slot and stoping method . T he mining method is suitable to the inclined thin and thickness orebody of the 101 stope , w hich is meaningful to safety and efficient of similar mines .
