摘要
主要介绍急倾斜破碎中厚富锰矿体用脉外采准、金属网木地梁假顶下向分层崩落采矿法回采时的采场结构、采准切割布置、回采工艺、采场地压控制技术、主要技术经济指标、材料消耗、评价及改进意见。
The structure of workings, get-ready slicing arrangement, stoping technology, workings＇ ground pressure control, major technical-economical parameters, material consumption, assessment and improving suggestion of downward slicing and crumbling method for steeply-inclined broken medium-sized rich manganese ore body of Heqing Manganese Co., Ltd are introduced.
