Talking about relation between the destruction depth of floor mining at flately inclined seam and actual mining parameters 浅释缓倾斜煤层底板采动破坏深度与回采参数关系
Application of caving mining technology with bottom under condition of flat dipping mid - thick body and unstable rock caused the most of trench and bottom drift , located in abutment , to be destroyed and low recovery in south area , xishimen iron mine 摘要在缓倾斜中厚矿体底板岩性不稳固的条件下，采用有底柱崩落法，由于电耙道大多处于空区边部应力集中的部位，致使堑沟及底部结构巷道破坏严重而使回收率极低，采用无底柱崩落卸压则可有效解决上述难题。
With the mining of no . 1 ore body which is solwly inclined , large and thick at the west flank of xinqiao pyrite mine as the example , analytic comparision is made between flat - back cut and fill stoping and sublevel open stoping with one - time delayed filling . the suggestion on the optimization of the mining and the discussion on appropraite mining method and the technical parameters of mining technology for slowly inclined large and thick ore body are also made 以新桥硫铁矿矿体西翼缓倾斜厚大矿体的开采为实例，对生产中应用的水平分层充填采矿法和分段空场嗣后一次充填采矿法进行分析比较，提出采矿方法的优化建议，探讨缓倾斜厚大矿体合适的采矿方法和采矿工艺技术参数。
