王坡矿瓦斯地质规律分析
|
摘要
为研究王坡矿瓦斯地质规律,运用瓦斯赋存构造逐级控制理论,结合搜集王坡矿瓦斯地质资料研究了矿区、矿井地质构造。在分析王坡矿地质构造特征的基础上,定性定量分析井田内地质构造、煤厚、煤层埋深、上覆基岩厚度、陷落柱对瓦斯赋存的影响,结果表明:影响瓦斯赋存的主控因素是上覆基岩厚度。利用上覆基岩厚度和瓦斯含量之间的关系,推出二者之间的线性关系方程,可用于深部瓦斯含量的预测。
For the study of Wangpo mine gas geological law,the use of gas occurrence tectonic gradual control theory,studies the mining area,combined with a large number of gas geological data of mine geological structure.Based on analyzing the characteristics of geological structure Wangpo mine,qualitative and quantitative analysis of ida in geological structure,coal thickness,buried depth of coal seam,overlying bedrock thickness,the influence of gas occurrence of collapse column,the results show that: the influence of main controlling factors of the gas occurrence is overlying bedrock thickness.Using the relationship between the overlying bedrock thickness and gas content,the linear relationship between the launch of the two equations,the prediction can be used for deep gas content.
