摘要
为了判断煤层群中各煤层突出危险性大小,基于对煤与瓦斯突出的预测指标与预测方法的综合分析,结合模糊数学,分级量化了评价指标,提出了煤层突出危险性的预评价方法,通过实例分析其可行性和实用性发现:该方法能反映煤层突出危险性大小且得出的量化评价结果有可比性。
In order to judge the large or small outburst danger in each seam of the seam group, based on the comprehensive analysis with the prediction index and predicted methods of the coal and gas outburst, in combined with the fuzzy mathematics, the paper quantized the evaluation indexes in classes and provided the pre-evaluation method of the seam outburst danger. The feasibility and practicability from the cause analysis showed that the prediction method could reflect the seam outburst danger large or small and could have the quantized evaluation result with the comparability.
