樊寨井田二1煤层瓦斯含量主控因素研究

    Study on the main control factors of Ⅱ1 coal gas content in Fanzhai mine field

    • 摘要: 为了查明樊寨井田瓦斯含量的主控因素,本文系统收集和统计了地质勘查阶段樊寨井田二1煤层的瓦斯地质资料,详细分析了地质构造、煤层埋深、基岩厚度、煤层厚度、煤层围岩、煤质等地质因素对煤层瓦斯含量的影响,应用回归分析方法建立以基岩厚度、煤层厚度、顶板20 m封闭系数为变量的瓦斯含量预测模型公式,并依据模型方程对井田二1煤层瓦斯含量进行了预测,为煤矿安全生产提供数据。

       

      Abstract: In order to find out the main control factors of gas content in Fanzhai field,this paper systematically collect the gas geological data of Ⅱ1 coal seam in Fanzhai mine field,and analyze the geological structure,burial depth,bedrock thickness,coal thickness,surrounding rock,coal quality and other geological factors on the coal gas content.Make bedrock thickness,coal thickness,roof closure coefficient of 20 meters as variables,use regression analysis method to establish the gas content prediction model.The gas content of Ⅱ1 coal seam is predicted according to the model equation.It is to provide safety data for the mine field.
