摘要
分段凿岩阶段矿房法是金岭铁矿的一种典型回采方法,为了适应不断变化的外界条件,在全矿几代工程技术人员的共同努力下,该采矿法已由最初的低分段发展为后来的高分段,不但为矿山节约了生产成本,还提高了采矿强度、劳动生产率以及作业安全性等矿山技术经济指标。同时也拓宽了阶段矿房法的标准设计方案,具有实践与理论的双重价值。
Sublevel rock drilling and stage room stoping is a typical method adopted in Jinling Iron Mine. To suit continuously changing external conditions, under the common efforts of the engineering and technical personnel of the whole mine, the stoping method has now adopted a high sublevel instead of the original low sublevel, which has not only reduced the production cost but also raised the mine＇s technical and economical indexes such as the mining intensity, labor productivity and operation safety. It has also widened the standard design plan for stage room stoping and therefore, has a doublevalue of both practice and theory.
