:急倾斜煤层放顶煤放煤巷道的支护不仅要维护巷道的稳定 ,还须有助于顶煤的破碎、放出 在总结和分析现场试验的基础上 ,运用模糊数学理论 ,建立了放煤巷道支护选型的综合评判模型 ,对放煤巷道的支护方案进行了优选 ,对推广急倾斜煤层放顶煤法有一定的指导意义 图 2 ,表 2 ,参
The caving roadway's support have to complete two tasks in the steep seam sub level caving.The one is to maintain the caving roadway stability,the another is to help the top coal to be broken.Based on summarizing and analyzing field test,a fuzzy comprehensive judgment model is established for selection on supports used in caving roadway by the fuzzy theory.The support pattern of caving roadway is optimized,which has fixed guiding significant in application and dissemination of the mining method.2figs.,2tabs.,6refs.
