Discussion of coal and gas outburst mechanism of syncline;

向斜构造煤与瓦斯突出机理探讨

The prospecting area is a NNE axial direction asymmetrical syncline,strata dip angle 26°~30°,deep part has igneous rock intrusive seriously impact coal seam hosting configurations.

勘探区为一轴向北北东向的不对称向斜构造,地层倾角26°～30,°测区深部有岩浆岩侵入体,严重影响煤层赋存形态;地表条件复杂,村庄密集、河流较多,测区东侧塌陷区水塘大面积分布,三维地震勘探野外施工难度大。

Taking the front floor as an example, mainly introduced the hoisting wedge driver installed in active pressing material core and making use of reverse wedge driver to form the up flanging structure.

Through the analyses of structure,coal seam,coal quality and coal lithological characters in the Panguan syncline,studied the CBM content of coalmines in the syncline.

在分析盘关向斜构造、煤层、煤质及煤岩特征基础上,对向斜内各矿井煤层气含量进行了研究,认为该区甲烷含量随煤化程度、深度、碳含量、镜质体含量增加而增加,随壳质体含量增加而下降,随矿物质增加而降低,与地下水活动的影响不明显。

Secondly,it reveals the controlling factors of the coalbed gas pools in the Panguan syncline by analyzing the construction evolution,surrounding .

首先通过对盘关向斜煤层分布、煤岩煤质特征及演化程度、煤储层物性、含气性、煤层气资源分布等的研究,弄清了盘关向斜煤层气成藏地质背景;其次从构造演化、围岩封闭性和煤层吸附性等方面,分析了盘关向斜煤层气成藏控制因素。
