基于分源预测法对基建矿井瓦斯涌出量的研究

Study on gas outburst quantity of capital construction mine based on separate source method

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,运用分源预测法对该矿瓦斯涌出量进行预测,得出郑庄煤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。

Forecast of Mine Gas Emission Provide the basis of the Gas emission for ventilation of mine and mining area and working face,The discretion of the prediction precision determines the mine safety production.In this paper,According to the Geological exploration of gas data and Geological data analysis the mine＇s development way and the occurrence of coal seam and coal quality,coal seam gas content distribution etc Use separate source method to predict the mine gas emission.Come to the conclusion that the Zhengzhuang coal mine is high gas mine,For the next step of mine design and safety management provides an important basis.
