地质动力区划预测煤与瓦斯突出

为了确定煤与瓦斯突出矿井的突出危险区域,威胁区域和安全区域,提出基于地质动力区划的多因素模式识别概率预测方法预测煤与瓦斯突出的新思路。以鸡西滴道矿立井为研究对象,利用地质动力区划方法确定不同尺度和级别构造运动的特征,建立板块构造学说与矿井工程实际的联系,将对矿井煤与瓦斯突出产生影响的因素为参数,采用多因素模式识别概率预测方法划分研究区域内的危险区域。研究表明该方法对煤与瓦斯突出区域预测的合理性与有效性,可以在实际工程中应用推广。

Prediction of Coal and Gas Outburst Based on Geo-dynamic Division

In order to determine the danger area,threat area and safety area in coal and gas outburst mines,new idea about the multi-factors pattern recognition and probability prediction method based on geological dynamic division is advanced,which aims to predict coal and gas outburst.Taking Jixi Didao mine as an example,the characteristics of structure movement with different scale and level were decided by using geological dynamic division method,and the relationship between plate structure theory and mining project was established.Then with the factors affecting coal and gas outburst as the parameters,the danger region was divided by the multi-factors pattern recognition and probability prediction method.This research indicates that the method is rational and effective in the prediction of coal and gas outburst region,and can be applied and popularized in the actual project.
