煤矿小块段精细区域预测的研究与应用

Research and Application of Small Block Prediction in Coal Mine

为探索煤矿开拓后区域突出危险性预测方法,以综合作用假说为理论基础,通过煤与瓦斯突出事故原因统计分析,提出了区域预测的主控因素(瓦斯、地应力)和重要因素(动力现象、煤体性质),建立了小块段精细区域预测方法。该方法适用于采掘工作面开拓后生产前的区域预测防突工序,可有效评判前方煤体突出危险性。

To explore the exploitation of coal mine after the regional outburst prediction method, basis on the hypothesis of comprehensive action, through the analysis of the cause of the accident statistics of coal and gas outburst, put forward the main control factors of regional prediction（gas, crustal stress）and important factors（the nature of dynamic phenomenon,the property of coal seam）, established a prediction method of small region. The method can be used to predict the outburst prevention process before the production of the working face, and it can be used to judge the outburst danger of the coal.
