基於分源預測法對礦井瓦斯湧出量預測研究

摘　要:礦井瓦斯湧出量預測為礦井、采區和工作麵通風提供瓦斯湧出方麵的基礎數據,其預測精度的高低直接決定著礦井正常生產時的安全生產。在鄭莊井田地勘瓦斯資料和地質資料分析的基礎上,根據礦井開拓方式、煤層賦存及煤質、煤層瓦斯含量分布規律等條件,運用分源預測法對鄭莊煤礦瓦斯湧出量進行預測,得出該礦為高瓦斯礦井的結論,為下一步礦井設計和安全管理提供了重要依據。

分類號:　TD712.5On the Prediction of Mine Gas Emission Rate Based on Predicted Method by Different Gas SourceHU Zhi-yun (Xianquan Goal Industry Go., Ltd. of Jinoheng Anthracite Mining Group, Changzhi 048007, Shanxi, China)Abstract:The prediction of mine gas emission rate provides basic data of gas emission for the ventilation of pits, mining areaand mining face, and the accuracy level of prediction directly determines the safety in production of mine during normalproduction. Based on the analysis of gas data and geological data of the geological prospecting of Zhengzhuang shaft area,according to the mine development ways, occurrence and coal qualityof coal seam, distribution laws of gas content in coal seamand other conditions, predicted method by different gas source has been used to predict the gas emission rate of mine, from whichit is concluded that Zhengzhuang Coal Mine is highly gassy mine, providing an important basis for further design and safetymanagement of mine.
