摘要
枣庄峄城石膏矿在原房柱式采矿法的基础上,着重研究了厚大石膏矿体的开采工艺、矿块结构参数及采场地压管理等问题,在保证回采过程安全的前提下,充分回收资源,提高资源利用率。
On the basis of maturely applying room and pillar method,such problems as mining technology,parameters fi xing,and stope pressure management in I thick and big gypsum orebody from Yicheng gypsum mine of Zaozhuang have been studied in this paper,we aim at not only ensuring mining safety,but also suffi ciently mining gypsum and improving utilizing rate of resources.
