针对短壁刀柱和巷柱开采后上部煤层蹬空开采的问题，结合煤层顶底板、水、火、瓦斯状况，利用比值判别法、“三带”判别理论、围岩平衡法和数理统计法研究了蹬空开采的可行性，并对可能遇到的情况提出了建议。
針對短壁刀柱和巷柱開採後上部煤層蹬空開採的問題，結閤煤層頂底闆、水、火、瓦斯狀況，利用比值判彆法、“三帶”判彆理論、圍巖平衡法和數理統計法研究瞭蹬空開採的可行性，併對可能遇到的情況提齣瞭建議。

For the problems of short wall wedge pillar and upward mining of the upper coal seam after mining roadway pillar, combined with the conditions of the coal seam roof and floor, water, fire and gas, the feasibility of overhead mining is researched by using ratio determination, “three zones” discriminant theory, surrounding rock balance method and mathematical statistics, and the suggestions for may encountering situations are proposed.
