成庄矿3^#煤层瓦斯赋存影响因素分析

Analysis on Factors Affected to Gas Deposit of No.3 seam in Chengzhuang Mine

根据成庄矿3#煤层瓦斯含量值与井田地质构造关系,运用地质构造控制理论,分析了成庄井田的瓦斯赋存特征,从瓦斯地质学的角度阐述了3#煤层瓦斯赋存与井田地质构造、煤层埋藏深度、煤层水分含量、煤层基岩厚度及顶板岩石厚度的关系,得出了煤层顶板泥岩厚度是影响3#煤层瓦斯赋存的最主要因素,同时分不同采区对瓦斯赋存的次要因素进行了分析,为今后有效地进行瓦斯预测及防治提供理论依据。

According to the relationship between the gas content value of No. 3 seam in Chengzhuang Mine and the geological structure of the minefield, the geological structure control theory was applied to analyze the gas deposit features of Chengzhuang Minefield. From the gas geology, the paper stated the relationship between No. 3 seam gas deposit and the minefield geological structure, seam deposit depth, seam base rock thickness and seam roof strata thickness. The roof mudstone thickness of seam was the main factor affected to No. 3 seam gas deposit. The secondary factors affected to the gas deposit in different mining blocks were analyzed and could provide the theoretical basis to the effective gas prediction and prevention.
