    Synergistic Prediction Technology of Coal and Gas Outburst of Far and Near Fields in High-efficiency Mine

    • 摘要: 为缓解高产高效矿井突出防治与生产之间的矛盾,抓住突出防治的首要环节(突出预测),围绕突出危险性的时空演化关系,构建了煤与瓦斯突出远近场协同预测技术体系。技术思路如下:首先,从远场预测角度建立瓦斯场、应力场、地质构造场及防突措施场,宏观把控矿井开采范围内突出危险性大小;然后,从近场预测角度建立基于瓦斯及矿压监测特征的突出预测方法,动态分析工作面突出危险性大小;最后,通过远近场预测的有效融合,实现对矿井突出危险性的远近场协同预测。

       

      Abstract: In order to alleviate the contradiction between outburst control and production in high-yield and high-efficiency mines, this paper focuses on the primary link of outburst control (outburst prediction), and constructs the far field and near field collaborative prediction technology and prediction model of coal and gas outburst around the time-space evolution relationship of outburst risk. The technical ideas of this paper are as follows: firstly, the gas field, stress field, geological structure field and outburst prevention measure field are established from the perspective of far-field prediction to realize the macro control of mine outburst risk; then the outburst prediction method based on the characteristics of gas and mine pressure monitoring are established from the perspective of near-field prediction to realize the dynamic analysis of the outburst risk of the working face; and finally, through the effective fusion of far-field and near-field prediction, the far-field and near-field collaborative prediction of mine outburst risk is realized.
