分析了李嘴孜煤矿A1煤层掘进工作面煤与瓦斯突出预测的主要指标,通过现场实测数据分析得出李嘴孜煤矿主要敏感指标,并利用模糊数学层次法对主要指标进行了重要性排序,为采煤工作面煤与瓦斯突出的预测和防治提供了科学的依据。
The main indexes of coal and gas outburst prediction in the driving face of A1 coal seam in LiZiZi coal mine are analyzed. The main sensitive indexes of LiZiZi coal mine are analyzed through field measurement data, and the main indexes are sorted by the fuzzy mathematics level method, It provides a scientific basis for prediction and prevention of coal and gas outburst in coal mining face.
