基于分源预测法对矿井瓦斯涌出量预测研究

摘　要:矿井瓦斯涌出量预测为矿井、采区和工作面通风提供瓦斯涌出方面的基础数据,其预测精度的高低直接决定着矿井正常生产时的安全生产。在郑庄井田地勘瓦斯资料和地质资料分析的基础上,根据矿井开拓方式、煤层赋存及煤质、煤层瓦斯含量分布规律等条件,运用分源预测法对郑庄煤矿瓦斯涌出量进行预测,得出该矿为高瓦斯矿井的结论,为下一步矿井设计和安全管理提供了重要依据。

分类号:　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.
