徐州王庄煤矿7煤瓦斯赋存时空规律研究

Study on Spatial Occurrence Rule of Gas in No.7 Coal Section in Wangzhuang Coal Mine

摘要:

该文在分析江苏徐州王庄煤矿山西组7煤层瓦斯赋存的控制条件的基础上，通过对煤层瓦斯含量与上覆基岩厚度、顶板20m含泥率及煤厚的相关性进行多元线性回归，研究了煤层瓦斯含量分布规律。又根据瓦斯地质数学模型法计算公式，得到了该煤矿回采工作面的瓦斯涌出量预测结果；并对矿井煤与瓦斯突出危险性区域进行预测。

Abstract:

On the basis of analyzing the controlling conditions of gas occurrence in No.7 coal section in Shanxi formation in Wangzhuang coal mine in Xuzhou city of Jiangsu province, by using multiple lines regression, correlation among gas content, thickness of overlying rock, mud rate at the depth of 20m of the roof, and the thickness of coal strata are introduced, distribution rule of gas content is studied as well. According to formula of geological and mathematical model, the predication result of gas emission in mine working face has been gained; and dangerous coal and gas outburstting regions are predicated.
