煤与瓦斯突出敏感地质指标研究

Study of sensitive geology factors of coal and gas outburst

以数量化理论Ⅲ为运算工具,介绍了煤与瓦斯突出敏感地质指标研究的方法原理,实现了瓦斯突出地质指标研究由定性向定量的转化,为煤与瓦斯突出的预测、预报及其防治提供了便利。以焦作中马村矿为例,对瓦斯突出敏感地质指标进行了筛选。结果表明,封闭性李庄断层、煤层分岔、砂岩顶板是该矿瓦斯突出的敏感地质指标。

With the calculation tool of the third theory of quantification, the basic theory of the study of sensitive geology factors of coal and gas outburst was introduced; the transform of the study of geology factors of coal and gas outburst from qualitative to quantitative was realized.The convenience of the forecast, prediction, prevention, and cure of coal and gas outburst was offered. As an example, the sensitive factors of Jiaozuo Zhong-macun coal mine were filtered.The result indicated that close Lizhuang fault,coal fork,and sandstone top board was sensitive geology factor influencing gas outburst of the mine.
