摘要
在现场观测和总结工业性试验的基础上 ,应用模糊数学理论建立了急倾斜煤层顶煤可放性的三级综合评判模型 ,模型能对顶煤的可放性作出了准确的判断。
A coal caving method in steep inclined seam is highly concerned due to its good mining benefit and safe conditions. This mining method has fully played the advantages of a good stable roof and coal easy falling in the steep inclined seam. Those advantages can eliminate the coal cutting operation and goaf handling operation which could highly save labor cost and improve the mining efficiency. But in the mining practices, many factors of mine rock pressure, seam characters should be considered.
