分源预测法在新建矿井3号煤层瓦斯涌出量预测中的应用

Application of Forecast from Different Sources on the No.3 Coal in New Mine Gas Emission Forecast

通过对某新建矿井大量的瓦斯资料和地质资料的整理分析得到各种地质条件、各种开采条件下的实际瓦斯涌出量;结合瓦斯基本理论,根据瓦斯原始含量、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,运用分源法对该新建矿3号煤层瓦斯涌出量进行预测,为该矿的通风设计,瓦斯抽放设计与瓦斯管理提供技术支持。

Through a lot of the new mine gas data and geological data , the present paper obtains actual gas emission on various geological condition, various mining condition after the reorganization analysis . Simulta-neously unifiesl the gas elementary theory, according to the gas primitive content ,the mine pit development way,the coal bed tax saves and the anthrax,condition and coal bed gas content distribution rule. By using the sub-source prediction method to carry on the forecast for the mine No.3 coal, through this picks the area the gas to well up the output to forecast to should pick the ventilate the design ,the gas pull out puts the design and the gas management provides the technical support, It has the certain instruction significance to this ore gas preventing and controlling work.
