煤与瓦斯突出规模与影响因素的定性定量关系

摘要

为提高煤与瓦斯突出规模预测的准确性，以林华煤矿有代表性的21次突出事故资料为基础，采用定性、定量相结合的方法，分析了突出规模与影响煤与瓦斯突出的因素之间的关系，以及各因素与突出规模的密切程度。研究表明，林华煤矿影响和控制突出规模的主要因素依次为埋深＞煤体破坏程度＞作业方式＝突出预兆＞地质构造，为突出规模的预测提供一种新思路。%To improve accuracy of prediction of coal and gas outburst scale , the author based on Linhua Coal Mine representative 21 outburst accident data.Using method of combining qualitative and quantitative to analysis of the relationship between outburst scale and influence factors of coal and gas outburst and the close degree between factors and outburst scale .Studies have shown that Lin Hua -mine the main factor to influence and control the outburst scale followed by buried depth >degree of destruction of coal >mode of opera-tion=prominent forecast >geological structure, provide a new way to forecast the outburst scale .
