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.
Underground engineering itself is not sure, the pre-thick coal seam for top-caving mining, it is necessary to accurately analyze the caving of its top coal, the traditional method of averaging and experience often can not accurately evaluate the objective things through The unascertained expectation of influencing many influencing factors of the top coal releasing is analyzed and the reasonable evaluation and classification of the top coal releasing can be carried out to provide a scientific basis for the top coal caving in the thick coal seam.According to the conclusion and Actually, the method deserves further study and discussion in the unascertained problems of underground engineering.
