摘要
地下工程本身具有未确知性,预对厚煤层进行放顶煤开采,需对其顶煤的冒放性进行准确地分析,传统的平均法和经验法往往不能对客观事物进行准确地评价.通过求解影响顶煤冒放性诸多影响因素的未确知期望,可实现对顶煤冒放性进行合理的评价与分类,为厚煤层进行放顶煤开采提供科学的依据.根据计算结果所得结论与实际相符,方法在处理地下工程等未确知问题中值得进一步研究探讨.
Substructure work has uncertainty itself. Need to accurately analyze the top coal caving and drawing characteristics in order to cave thick coal. Usually the traditional average method and experience method can＇t analyze accurately. In order to solve the impacting factor ＇s unascertained expectation which impact the top coal caving and drawing characteristics, we can evaluate and classify the top coal caving and drawing characteristics in reason and provide scientific foundation for caving of thick coal. The conclusion can match practice by calculating so this method is worth to researching in solving the unascertalned matters of substructure work.
