| 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。本文简要介绍该方法的原理、方案结构、安全措施及应用效果，供借鉴。

| Abstract: | 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. To resolve the problems the caving mining technology without bottom was tested and principle, parameter, result of using the technology are presented in the paper. |
